Jinbin Hu, Zikai Zhou, Jin Zhang	Lightweight Automatic ECN Tuning Based on Deep Reinforcement Learning With Ultra-Low Overhead in Datacenter Networks	2024	Early Access	Tuning Degradation Throughput	In modern datacenter networks (DCNs), mainstream congestion control (CC) mechanisms essentially rely on Explicit Congestion Notification (ECN) to reflect congestion. The traditional static ECN threshold performs poorly under dynamic scenarios, and setting a proper ECN threshold under various traffic patterns is challenging and time-consuming. The recently proposed reinforcement learning (RL) based ECN Tuning algorithm (ACC) consumes a large number of computational resources, making it difficult to deploy on switches. In this paper, we present a lightweight and hierarchical automated ECN tuning algorithm called LAECN, which can fully exploit the performance benefits of deep reinforcement learning with ultra-low overhead. The simulation results show that LAECN improves performance significantly by reducing latency and increasing throughput in stable network conditions, and also shows consistent high performance in small flows network environments. For example, LAECN effectively improves throughput by up to 47%, 34%, 32% and 24% over DCQCN, TIMELY, HPCC and ACC, respectively.	10.1109/TNSM.2024.3450596
Jin Ye, Tiantian Yu, Zhaoyi Li, Jiawei Huang	SAR: Receiver-driven Transport Protocol with Micro-burst Prediction in Data Center Networks	2024	Early Access	Bandwidth Transport protocols Switches	In recent years, motivated by new datacenter applications and the well-known shortcomings of TCP in data center, many receiver-driven transport protocols have been proposed to provide ultra-low latency and zero packet loss by using the proactive congestion control. However, in the scenario of mixed short and long flows, the short flows with ON/OFF pattern generate micro-burst traffic, which significantly deteriorates the performance of existing receiver-driven transport protocols. Firstly, when the short flows turn into ON mode, the long flows cannot immediately concede bandwidth to the short ones, resulting in queue buildup and even packet loss. Secondly, when the short flows change from ON to OFF mode, the released bandwidth cannot be fully utilized by the long flows, leading to serious bandwidth waste. To address these issues, we propose a new receiver-driven transport protocol, called SAR, which predicts the micro burst generated by short flows and adjusts the sending rate of long flows accordingly. With the aid of micro-burst prediction mechanism, SAR mitigates the bandwidth competition due to the arrival of short flows, and alleviates the bandwidth waste when the short flows leave. The testbed and NS2 simulation experiments demonstrate that SAR reduces the average flow completion time (AFCT) by up to 66% compared to typical receiver-driven transport protocols.	10.1109/TNSM.2024.3450597
Dan Tang, Xiaocai Wang, Keqin Li, Chao Yin, Wei Liang, Jiliang Zhang	FAPM: A Fake Amplification Phenomenon Monitor to Filter DRDoS Attacks With P4 Data Plane	2024	Early Access	Switches Servers IP networks	Distributed Reflection Denial-of-Service (DRDoS) attacks have caused significant destructive effects by virtue of emerging protocol vulnerabilities and amplification advantages, and their intensity is increasing. The emergence of programmable data plane supporting line-rate forwarding provides a new opportunity for fine-grained and efficient attack detection. This paper proposed a light-weight DRDoS attack detection and mitigation system called FAPM, which is deployed at the victim end with the intention of detecting the amplification behavior caused by the attack. It places the work of collecting and calculating reflection features on the data plane operated by ''latter window assisting former window'' mechanism, and arranges complex identification and regulation logic on the control plane. This approach avoids the hardware constraints of the programmable switch while leveraging their per-packet processing capability. Also, it reduces communication traffic significantly through feature compression and state transitions. Experiments show that FAPM has (1) fast response capability within seconds (2) a memory footprint at the KB level and communication overhead of 1 Kbps, and (3) good robustness.	10.1109/TNSM.2024.3449889
Hossein Taghizadeh, Bardia Safaei, Amir Mahdi Hosseini Monazzah, Elyas Oustad, Sahar Rezagholi Lalani, Alireza Ejlali	LANTERN:Learning-Based Routing Policy for Reliable Energy-Harvesting IoT Networks	2024	Early Access	Routing Internet of Things Measurement	RPL is introduced to conduct path selection in Lowpower and Lossy Networks (LLN), including IoT. A routing policy in RPL is governed by its objective function, which corresponds to the requirements of the IoT application, e.g., energy-efficiency, and reliability in terms of Packet Delivery Ratio (PDR). In many applications, it is not possible to connect the nodes to the power outlet. Also, since nodes may be geographically inaccessible, replacing the depleted batteries is infeasible. Hence, harvesters are an admirable replacement for traditional batteries to prevent energy hole problem, and consequently to enhance the lifetime and reliability of IoT networks. Nevertheless, the unstable level of energy absorption in harvesters necessitates developing a routing policy, which could consider harvesting aspects. Furthermore, since the rates of absorption, and consumption are incredibly dynamic in different parts of the network, learningbased techniques could be employed in the routing process to provide energy-efficiency. Accordingly, this paper introduces LANTERN; a learning-based routing policy for improving PDR in energy-harvesting IoT networks. In addition to the rate of energy absorption, and consumption, LANTERN utilizes the remaining energy in its routing policy. In this regard, LANTERN introduces a novel routing metric called Energy Exponential Moving Average (EEMA) to perform its path selection. Based on diversified simulations conducted in Cooja, with prolonging the lifetime of the network by 5.7x, and mitigating the probability of energy hole problem, LANTERN improves the PDR by up to 97%, compared to the state-of-the-art. Also, the consumed energy per successfully delivered packet is reduced by 76%.	10.1109/TNSM.2024.3450011
Xiwen Jie, Jiangping Han, Guanglei Chen, Hang Wang, Peilin Hong, Kaiping Xue	CACC: A Congestion-Aware Control Mechanism to Reduce INT Overhead and PFC Pause Delay	2024	Early Access	Delays Throughput Accuracy	Nowadays, Remote Direct Memory Access (RDMA) is gaining popularity in data centers for low CPU overhead, high throughput, and ultra-low latency. As one of the state-ofthe-art RDMA Congestion Control (CC) mechanisms, HPCC leverages the In-band Network Telemetry (INT) features to achieve accurate control and significantly shortens the Flow Completion Time (FCT) for short flows. However, there exists redundant INT information increasing the processing latency at switches and affecting flows throughput. Besides, its end-to-end feedback mechanism is not timely enough to help senders cope well with bursty traffic, and there still exists a high probability of triggering Priority-based Flow Control (PFC) pauses under large-scale incast. In this paper, we propose a Congestion-Aware (CA) control mechanism called CACC, which attempts to push CC to the theoretical low INT overhead and PFC pause delay. CACC introduces two CA algorithms to quantize switch buffer and egress port congestion, separately, along with a fine-grained window size adjustment algorithm at the sender. Specifically, the buffer CA algorithm perceives large-scale congestion that may trigger PFC pauses and provides early feedback, significantly reducing the PFC pause delay. The egress port CA algorithm perceives the link state and selectively inserts useful INT data, achieving lower queue sizes and reducing the average overhead per packet from 42 bytes to 2 bits. In our evaluation, compared with HPCC, PINT, and Bolt, CACC shortens the average and tail FCT by up to 27% and 60.1%, respectively.	10.1109/TNSM.2024.3449699
Hui Wang, Zhenyu Yang, Ming Li, Xiaowei Zhang, Yanlan Hu, Donghui Hu	CoSIS: A Secure, Scalability, Decentralized Blockchain via Complexity Theory	2024	Early Access	Blockchains Protocols Security	As the origin of blockchains, the Nakamoto Consensus protocol is the primary protocol for many public blockchains (e.g., Bitcoin) used in cryptocurrencies. Blockchains need to be decentralized as a core feature, yet it is difficult to strike a balance between scalability and security. Many approaches to improving blockchain scalability often result in diminished security or compromise the decentralized nature of the system. Inspired by network science, especially the epidemic model, we try to solve this problem by mapping the propagation of transactions and blocks as two interacting epidemics, called the CoSIS model. We extend the transaction propagation process to increase the efficiency of block propagation, which reduces the number of unknown transactions. The reduction of the block propagation latency ultimately increases the blockchain throughput. The theory of complex networks is employed to offer an optimal boundary condition. Finally, the node scores are stored in the chain, so that it also provides a new incentive approach. Our experiments show that CoSIS accelerates blocks!/ propagation and TPS is raised by 20% ~ 33% on average. At the same time, the system security can be significantly improved, as an orphaned block rate is close to zero in better cases. CoSIS enhances the scalability and security of the blockchain while ensuring that all changes do not compromise the decentralized nature of the blockchain.	10.1109/TNSM.2024.3449575
Ehsan Nowroozi, Nada Jadalla, Samaneh Ghelichkhani, Alireza Jolfaei	Mitigating Label Flipping Attacks in Malicious URL Detectors Using Ensemble Trees	2024	Early Access	Training Accuracy Classification tree analysis	Malicious URLs present significant threats to businesses, such as transportation and banking, causing disruptions in business operations. It is essential to identify these URLs; however, existing Machine Learning models are vulnerable to backdoor attacks. These attacks involve manipulating a small portion of the training data labels, such as Label Flipping, which can lead to misclassification. Therefore, it is crucial to incorporate defense mechanisms into machine-learning models to protect against such attacks. The focus of this study is on backdoor attacks in the context of URL detection using ensemble trees. By illuminating the motivations behind such attacks, highlighting the roles of attackers, and emphasizing the critical importance of effective defense strategies, this paper contributes to the ongoing efforts to fortify machine-learning models against adversarial threats within the machine-learning domain in network security. We propose an innovative alarm system that detects the presence of poisoned labels and a defense mechanism designed to uncover the original class labels with the aim of mitigating backdoor attacks on ensemble tree classifiers. We conducted a case study using the Alexa and Phishing Site URL datasets and showed that label-flipping attacks can be addressed using our proposed defense mechanism. Our experimental results prove that the Label Flipping attack achieved an Attack Success Rate between 50-65% within 2-5%, and the innovative defense method successfully detected poisoned labels with an accuracy of up to 100%.	10.1109/TNSM.2024.3447411
Sushmit Bhattacharjee, Konstantinos Alexandris, Thomas Bauschert	Multi-Domain TSN Orchestration & Management for Large-Scale Industrial Networks	2024	Early Access	Bridges Streams Protocols	The increasing demand for determinism in modern industrial communication, driven by Industry 4.0, has led to the development of IEEE Time-Sensitive Networking (TSN) standards. However, integrating and configuring interconnected heterogeneous industrial networks remains a significant challenge. This paper extends the novel hierarchical Software-Defined Networking (SDN) based architectural design and control plane framework introduced in the context of orchestration and management of a multi-domain TSN network. We present relevant data models and a signaling schema essential for establishing end-to-end inter-domain time-sensitive streams within the proposed architecture. A proof-of-concept implementation validates the feasibility of the framework and demonstrates its performance advantages over the peer-to-peer model. The scalability of the framework for large-scale industrial networks is verified, and it ensures secure information encapsulation among domains, enabling seamless integration of multi-vendor heterogeneous applications. Furthermore, we investigate the use of CORECONF as a lightweight alternative to NETCONF for network management of multi-domain TSN network, providing experimental results.	10.1109/TNSM.2024.3447789
Amar Rasheed, Mohamed Baza, Gautam Srivastava, Narashimha Karpoor, Cihan Varol	IoTDL2AIDS: Towards IoT-Based System Architecture Supporting Distributed LSTM Learning for Adaptive IDS on UAS	2024	Early Access	Training Computational modeling Adaptation models	The rapid proliferation of Unmanned Aircraft Systems (UAS) introduces new threats to national security. UAS technologies have dramatically revolutionized legitimate business operations while providing powerful weaponizing systems to malicious actors and criminals. Due to their inherited wireless capabilities, they are an easy target for cyber threats. In response to this challenge, the implementation of many Intrusion Detection Systems (IDS), which support anomaly detection on UAS, have been proposed in the past. However, such systems often require offline training with heavy processing, making them unsuitable for UAS deployment. This is pertinent for drone systems that support dynamic changes in mission operational tasks. This paper presents a novel system architecture that utilizes sensing systems capabilities available on existing IoT infrastructure for supporting rapid infield adaptive models training and parameters estimation services for UAS. We have devised a cluster-oriented distributed training algorithm based on LSTM with mini-batch gradient descent, with hundreds of IoT platforms per cluster collaboratively performing model parameters estimation tasks. The proposed architecture is based on deploying a multilayer system that facilitates secure dissemination of power consumption behavioral patterns for the flight sensing system between the UAS layer and the IoT layer. The model was implemented and deployed on a real IoT-enabled platform based on NXP-Kinetis K64 ̶ 120 MHz. Furthermore, model training and validation were performed by applying various datasets contaminated with different percentages of malicious data. Our anomaly detection model achieved high prediction accuracy with an ROC-AUC score of 0.9332. The model maintains minimal power consumption overheads and low training time during the processing of a data batch.	10.1109/TNSM.2024.3448312
Shigen Shen, Xuanbin Hao, Zhengjun Gao, Guowen Wu, Yizhou Shen, Hong Zhang, Qiying Cao, Shui Yu	SAC-PP: Jointly Optimizing Privacy Protection and Computation Offloading for Mobile Edge Computing	2024	Early Access	Privacy Task analysis Entropy	The emergence of mobile edge computing (MEC) imposes an unprecedented pressure on privacy protection, although it helps the improvement of computation performance including energy consumption and computation delay by computation offloading. To this end, we concern about the privacy protection in the MEC system with a curious edge server. We present a deep reinforcement learning (DRL)-driven computation offloading strategy designed to concurrently optimize privacy protection and computation cost. We investigate the potential privacy breaches resulting from offloading patterns, propose an attack model of privacy theft, and correspondingly define an analytical measure to assess privacy protection levels. In pursuit of an ideal computation offloading approach, we propose an algorithm, SAC-PP, which integrates actor-critic, off-policy, and maximum entropy to improve the efficiency of learning processes. We explore the sensitivity of SAC-PP to hyperparameters and the results demonstrate its stability, which facilitates application and deployment in real environments. The relationship between privacy protection and computation cost is analyzed with different reward factors. Compared with benchmarks, the empirical results from simulations illustrate that the proposed computation offloading approach exhibits enhanced learning speed and overall performance.	10.1109/TNSM.2024.3447753
Tailai Song, Gianluca Perna, Paolo Garza, Michela Meo, Maurizio Matteo Munafò	Packet Loss in Real-Time Communications: Can ML Tame its Unpredictable Nature?	2024	Early Access	Packet loss Quality of experience Task analysis	Due to the flourishing development of networks, and abetted by the Covid-19 pandemic, we have witnessed an exponential surge in the global proliferation of Real-Time Communications (RTC) applications in recent years. In light of this, the necessity for robust, scalable, and intelligent network infrastructures and technologies has become increasingly apparent. Among the principal challenges encountered in RTC lies the issue of packet loss. Indeed, the occurrence of losses leads to communication degradation and reallocation that adversely affect the Quality of Experience (QoE). In this paper, we investigate the feasibility of predicting packet loss phenomena through the utilization of machine learning techniques, solely based on statistics derived directly from packets. We provide different definitions of packet loss, subsequently focusing on the most critical scenario, which is defined as the first loss of a series. By delineating the concept of loss, we propose different problem formulations to determine whether there exists a mathematically advantageous scenario over others. To substantiate our analysis, we demonstrate that these phenomena can be correctly identified with a recall up to 66%, leveraging three ample datasets of RTC traffic, which were collected under distinct conditions at different times, further solidifying the validity of our findings.	10.1109/TNSM.2024.3442616
Mahsa Raeiszadeh, Amin Ebrahimzadeh, Roch H. Glitho, Johan Eker, Raquel A. F. Mini	Real-Time Adaptive Anomaly Detection in Industrial IoT Environments	2024	Early Access	Anomaly detection Industrial Internet of Things Real-time systems	To ensure reliability and service availability, nextgeneration networks are expected to rely on automated anomaly detection systems powered by advanced machine learning methods with the capability of handling multi-dimensional data. Such multi-dimensional, heterogeneous data occurs mostly in todays Industrial Internet of Things (IIoT), where real-time detection of anomalies is critical to prevent impending failures and resolve them in a timely manner. However, existing anomaly detection methods often fall short of effectively coping with the complexity and dynamism of multi-dimensional data streams in IIoT. In this paper, we propose an adaptive method for detecting anomalies in IIoT streaming data utilizing a multi-source prediction model and concept drift adaptation. The proposed anomaly detection algorithm merges a prediction model into a novel drift adaptation method resulting in accurate and efficient anomaly detection that exhibits improved scalability. Our trace-driven evaluations indicate that the proposed method outperforms the state-of-theart anomaly detection methods by achieving up to an 89.71 accuracy (in terms of Area under the Curve (AUC)) while meeting the given efficiency and scalability requirements.	10.1109/TNSM.2024.3447532
Cong Zhou, Baokang Zhao, Fengxiao Tang, Biao Han, Baosheng Wang	Dynamic Multi-objective Service Function Chain Placement Based on Deep Reinforcement Learning	2024	Early Access	Optimization Heuristic algorithms Vectors	Service function chain placement is crucial to support services flexibility and diversity for different users and vendors. Specifically, this problem is proved to be NP-hard. Existing deep reinforcement learning based methods either can only handle a limited number of objectives, or their training time are too long. Concomitantly, they are unable to satisfy when the number of objectives is dynamic. It is necessary to model service function chain placement as a multi-objective problem. The multi-objective problem can decomposed into multiple subproblems by the weight vectors. In this paper, we first reveal the relationship between weight vectors and solution position, which can reduce the training time to gain a better placement model. Then, we design a novel algorithm for the service function chain placement problem, called rzMODRL. The weight vectors are divided into zones for training in parallel, and the order is defined for the final models located at the end of a training process, which can save time and improve the quality of the model. Dynamic objective placement method is based on the high-dimensional model to avoid retraining for a low-dimensional placement. Evaluation results show that the proposed algorithms improve the service acceptance ratio up to 32% and the hyper-volume values with 14% in the multi-objective service function chain placement, where hyper-volume has been widely applied to evaluate the convergence and diversity simultaneously in multi-objective optimization. And it is also effective in solving the dynamic objective service function chain placement problem that the difference of average hyper-volume values is 10.44%	10.1109/TNSM.2024.3446248
Kumar Prateek, Soumyadev Maity, Neetesh Saxena	QSKA: A Quantum Secured Privacy-Preserving Mutual Authentication Scheme for Energy Internet-Based Vehicle-to-Grid Communication	2024	Early Access	Privacy-Preserving Authentication Security Threats Vehicle-to-Grid	Energy Internet is well-known nowadays for enabling bidirectional V2G communication; however, with communication and computation abilities, V2G systems become vulnerable to cyber-attacks and unauthorised access. An authentication protocol verifies the identity of an entity, establishes trust, and allows access to authorized resources while preventing unauthorized access. Research challenges for vehicle-to-grid authentication protocols include quantum security, privacy, resilience to attacks, and interoperability. The majority of authentication protocols in V2G systems are based on public-key cryptography and depend on some hard problems like integer factorization and discrete logs to guarantee security, which can be easily broken by a quantum adversary. Besides, ensuring both information security and entity privacy is equally crucial in V2G scenarios. Consequently, this work proposes a quantum-secured privacy-preserving key authentication and communication (QSKA) protocol using superdense coding and a hash function for unconditionally secure V2G communication and privacy. QSKA uses a password-based authentication mechanism, enabling V2G entities to securely transfer passwords using superdense coding. The QSKA security verification is performed in proof-assistant Coq. The security analysis and performance evaluation of the QSKA show its resiliency against well-known security attacks and reveal its enhanced reliability and efficiency with respect to state-of-the-art protocols in terms of computation, communication, and energy overhead.	10.1109/TNSM.2024.3445972
Ankur Mudgal, Abhishek Verma, Munesh Singh, Kshira Sagar Sahoo, Erik Elmroth, Monowar Bhuyan	FloRa: Flow Table Low-Rate Overflow Reconnaissance and Detection in SDN	2024	Early Access	Flora Denial-of-service attack Protocols	SDN has evolved to revolutionize next-generation networks, offering programmability for on-the-fly service provisioning, primarily supported by the OpenFlow (OF) protocol. The limited storage capacity of Ternary Content Addressable Memory (TCAM) for storing flow tables in OF switches introduces vulnerabilities, notably the Low-Rate Flow Table Overflow (LOFT) attacks. LOFT exploits the flow table’s storage capacity by occupying a substantial amount of space with malicious flow, leading to a gradual degradation in the flow-forwarding performance of OF switches. To mitigate this threat, we propose FloRa, a machine learning-based solution designed for monitoring and detecting LOFT attacks in SDN. FloRa continuously examines and determines the status of the flow table by closely examining the features of the flow table entries. When suspicious activity is identified, FloRa promptly activates the machine-learning based detection module. The module monitors flow properties, identifies malicious flows, and blacklists them, facilitating their eviction from the flow table. Incorporating novel features such as Packet Arrival Frequency, Content Relevance Score, and Possible Spoofed IP along with Cat Boost employed as the attack detection method. The proposed method reduces CPU overhead, memory overhead, and classification latency significantly and achieves a detection accuracy of 99.49% which is more than the state-of-the-art methods to the best of our knowledge. This approach not only protects the integrity of the flow tables but also guarantees the uninterrupted flow of legitimate traffic. Experimental results indicate the effectiveness of FloRa in LOFT attack detection, ensuring uninterrupted data forwarding and continuous availability of flow table resources in SDN.	10.1109/TNSM.2024.3446178
Xiaohuan Li, Bitao Chen, Junchuan Fan, Jiawen Kang, Jin Ye, Xun Wang, Dusit Niyato	Cloud-Edge-End Collaborative Intelligent Service Computation Offloading: A Digital Twin Driven Edge Coalition Approach for Industrial IoT	2024	Early Access	Cloud computing Industrial Internet of Things Task analysis	By using the intelligent edge computing technologies, a large number of computing tasks of end devices in Industrial Internet of Things (IIoT) can be offloaded to edge servers, which can effectively alleviate the burden and enhance the performance of IIoT. However, in large-scale multi-service-oriented IIoT scenarios, offloading service resources are heterogeneous and offloading requirements are mutually exclusive and time-varying, which reduce the offloading efficiency. In this paper, we propose a cloud-edge-end collaboration intelligent service computation offloading scheme based on Digital Twin (DT) driven Edge Coalition Formation (DECF) approach to improve the offloading efficiency and the total utility of edge servers, respectively. Firstly, we establish a DT model to obtain accurate digital representations of heterogeneous end devices and network state parameters in dynamic and complex IIoT scenarios. The DT model can capture time-varying requirements in a low latency manner. Secondly, we formulate two optimization problems to maximize the offloading throughput and total system utility. Finally, we convert the multiobjective optimization problems to a Stackelberg coalition game model and develop a distributed coalition formation approach to balance the two optimizing objectives. Simulation results indicate that, compared with the nearest coalition scheme and non-coalition scheme, the proposed approach achieves offloading throughput improvements of 11.5% and 148%, and enhances the overall utility by 12% and 170%, respectively.	10.1109/TNSM.2024.3441231
Menglan Hu, Hao Wang, Xiaohui Xu, Jianwen He, Yi Hu, Tianping Deng, Kai Peng	Joint Optimization of Microservice Deployment and Routing in Edge via Multi-Objective Deep Reinforcement Learning	2024	Early Access	Microservice architectures Routing Heuristic algorithms	Edge computing technologies with container-based microservice architectures promise to provide stable and low-latency services for large-scale and complex edge applications. However, due to the limited CPU and storage resources in edge computing scenarios, the coarse-grained service deployment on edge nodes causes performance bottlenecks. In addition, the effective deployment of microservices is tightly correlated with request routing, but the current research ignores the joint optimization of multi-instance deployment and routing. In this paper, we first model the problem of jointly optimizing service deployment and routing in a dynamically changing environment with multi-edge network collaboration based on a queuing network analysis. Secondly, we design heuristic algorithms to scale microservice instances horizontally in dynamic user request states. In addition, we propose a reinforcement learning algorithm based on reward shaping (RSPPO) to minimize user waiting delay and edge network resource consumption. We also solve the microservice deployment and request routing problem for multi-edge collaboration to achieve load balancing among edge nodes. Finally, extensive experiments verify the significant and extensive effectiveness of our algorithm.	10.1109/TNSM.2024.3443872
Xin Wang, Jianhui Lv, Adam Slowik, B.D. Parameshachari, Keqin Li, Chien-Ming Chen, Saru Kumari	DLLF-2EN: Energy-Efficient Next Generation Mobile Network With Deep Learning-Based Load Forecasting	2024	Early Access	Energy efficiency Base stations Next generation networking	The exponential growth of mobile data traffic in next generation networks has led to a significant increase in energy consumption, posing critical challenges for network operators. We propose DLLF-2EN, a novel energy-efficient framework that integrates deep learning-based load forecasting, an advanced power consumption model, and a comprehensive energy-saving strategy to address this issue. The load forecasting technique utilizes deep convolutional neural network and long short-term memory model, which is based on deep learning. This model is capable of capturing the spatiotemporal dependencies present in network traffic data. The power consumption model accurately characterizes the base stations’ static and dynamic power consumption components, facilitating the assessment of energy efficiency under various network scenarios. The energy-saving strategy combines base station sleep mode with discontinuous transmission and reception, as well as lightweight transmission of common signals, dynamically adapting the network operation based on the predicted traffic load. Furthermore, DLLF-2EN incorporates an intelligent power management system that leverages machine learning algorithms to continuously monitor the network, analyze collected data, and make optimal energy-saving decisions in real-time. Simulation demonstrate that the superior performance of DLLF-2EN in terms of load forecasting accuracy and energy efficiency compared to state-of-the-art baseline methods. The proposed framework represents a comprehensive solution for energy-efficient and sustainable next generation mobile networks, addressing the critical challenges of minimizing energy consumption while meeting the growing demands for high-quality mobile services.	10.1109/TNSM.2024.3445369
Yong Xiao, Jianxun Liu, Guosheng Kang, Buqing Cao	Group Feature Aggregation for Web Service Recommendations	2024	Early Access	Task analysis Web services Interviews	Increasingly low barriers to Internet applications allow a large number of ordinary users to become developers or users of Web services. However, confronted with massive services and complex application scenarios, users often struggle to filter out satisfactory services, in fact, even professional users find it difficult to describe their requirements specifically and accurately in many cases. In order to aggregate more feature information and mitigate the negative impact of low-quality user requirement description, we propose a novel group feature aggregation service recommendation framework (GFASR). Concretely, we first calculate the semantic similarity between users, and create a group for each user according to the similarity ranking. Furthermore, on the basis of learning neural embeddings of users, candidate services, and groups, we employ a dual-attention mechanism to capture effective feature (such as requirement description, service history invoked information, etc.) and preference information of group members for each user, thereby supplementing or enhancing the user’s feature representation. Finally, we aggregate and propagate the information of all embeddings, and a neural and attentional factorization machine model is used to recommend services for users. Comparative experiments on a real dataset demonstrate that our method significantly outperforms the state-of-the-art service recommendation models.	10.1109/TNSM.2024.3444275
Xu Yu, Yan Lu, Feng Jiang, Qiang Hu, Junwei Du, Dunwei Gong	A Cross-Domain Intrusion Detection Method Based on Nonlinear Augmented Explicit Features	2024	Early Access	Feature extraction Intrusion detection Internet of Things	The purpose of Intrusion Detection Systems (IDS) is to identify security issues in data transmitted by various devices and communication protocols. For domains with sparse data, such as the Internet of Things (IoT), cross-domain models are applied to solve the sparse problem by transfer knowledge from the source domain with rich data to the target domain. However, most of the cross-domain intrusion detection methods map different explicit features in the source and target domains to implicit features in a common implicit space, which weakens the interpretability of these methods. To enhance the interpretability of cross-domain models, we propose a Cross-Domain Intrusion Detection Method Based on Nonlinear Augmented Explicit Features (NAEF). Specifically, we augment the feature space of the source and target domains as the combination of shared features, source domain specific features and target domain specific features. Moreover, we model the nonlinear mapping relationship from shared features to special features in the source and target domains separately. Then, the original features in the source and target domains are mapped to uniform explicit features in the augmented space by migration of the nonlinear mapping relationship. Additionally, a classifier based on ensemble learning and attention mechanism balances the data distribution and selects important features to enhance detection performance. Our experimental results demonstrate the effectiveness of the proposed NAEF method on four public datasets.	10.1109/TNSM.2024.3444909
