Big data management in the IDS system presents several important issues, such as delayed reaction times, imbalanced datasets, reduced detection rates, and false alarm rates. To overcome those drawbacks, this work introduces a novel Intrusion Detection System from the perspective of big data handling. Here, input data is handled with the Apache Spark. In the first phase (preprocessing), improved min–max normalization is performed. Subsequently, improved correlation and flow features are extracted since the information extraction from the data is more important to determine the appropriate class differences during attack detection. Subsequently, intrusion detection is done by a hybrid model, which fuses the long short term memory and optimized convolutional neural network (CNN). Then, the optimization-assisted training algorithm called elephant adapted cat swarm optimization (EA-CSO) is proposed that tunes the optimal weights of CNN to enhance the performance of detection. Finally, the performance of the adopted model is validated over the traditional models in terms of positive, negative and other metrics, and the proposed work shows its better performance over the other models. The accuracy of detecting the intrusions using the HC + EA-CSO model at 90th LP is high around 95.029 while other conventional models obtain minimal accuracy.</p>","PeriodicalId":23750,"journal":{"name":"Wireless Networks","volume":"33 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141772782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, we address the challenge of sum-rate maximization in D2D networks by formulating it as a reinforcement learning problem. In our approach, STGNNs act as agents, generating optimal power allocations to maximize the reward function, which is the overall sum-rate of the network. Our study operates under the realistic assumption of delayed, local channel state information (CSI). Various user mobility patterns, including constant positions, velocities, and accelerations are simulated. The robustness of our proposed method is evaluated against delayed and noisy CSI, which are crucial factors in real-world scenarios. Furthermore, the fairness of our approach is compared to the well-established load-spillage algorithm, which is guaranteed to converge to the globally optimal solution of the alpha-fair utility maximization problem. Finally, the convergence behavior of our method is analyzed in comparison to the policy gradient approach. Our empirical results demonstrate that the proposed STGNN significantly outperforms both the WMMSE benchmark and memoryless graph neural networks (GNNs) across all simulated scenarios, and converges to the globally optimal solution of the load-spillage algorithm, with lower computational complexity. Specifically, it achieves a remarkable performance gap of over 400% compared to the WMMSE algorithm and approximately 10% improvement over the memoryless GNN.

Further, these features may lead to the self-managed networking model, in which it faces numerous confronts in the network lifetime, fault tolerance, and energy consumption depending upon the non-renewable energy resources. The major advantages of the WSNs are regarded as the monitoring process as well as the nodes used in this network model are positioned commonly in harsh environments. Network management and its efficiency are considered as the most significant factor in network operation. Then, the faults in the WSN have been categorized in terms of persistence, behavior, and underlying causes according to the observation time. Due to its underlying causes in the WSN, the faults are categorized as incorrect computation fault, timing, omission, crash, and fail and stop. Consequently, due to the persistence, the faults are then categorized as a transient fault, intermittent, and permanent, and due to the behaviors, the fault is categorized as a soft and hard fault. As the recent conventional fault detection models failed to provide significant applications in WSN, this work suggests a new way of performing fault tolerance in WSN. In this research, a newly derived technique is implemented by using two functions like energy level checker and a routing manager for fault tolerance to detect malicious nodes in WSN. Here, the Energy level checker checks the residual energy for each communication. If the energy dissipation for a particular communication is less or higher than the threshold it does not send the packet, instead, it forwards the warning messages of the transmitted node that is further sent to the energy level checker. Next, the routing manager sends the path verification packets to the path, if acknowledgment is received, then, the packet is transmitted, and also Certificate Authority is issued to the trusted node based upon the amount of data packets transmitted and the amount of data packets that are successfully obtained. Finally, the prevention of fault nodes is done by selecting the trusted node using a new optimization algorithm known as the Modified Sandpiper Optimization Algorithm derived from the Sandpiper Optimization Algorithm. Another contribution of this WSN network for routing is the Cluster Head selection, which is carried out by solving the multi-objective function regarding constraints like trust, residual energy, distance, and delay. Moreover, the simulations have shown comparatively more success over others.</p>","PeriodicalId":23750,"journal":{"name":"Wireless Networks","volume":"3 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141574557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, considering the existence of the eavesdropping user, an SS-DBS model, consisting of a baseband processing subsystem, an energy subsystem, and a radio frequency subsystem, is established for downlink secure transmission at the physical layer. Among the model, the remote radio frequency units are divided into secure remote radio frequency units that transmit secure information to the legitimate user and friendly cooperative remote radio frequency units that transmit artificial noise to interfere with the eavesdropping user. On this basis, a joint optimization problem of energy sharing, power allocation, and RRFU selection with the objective of maximizing the secure information rate of system is formulated. To solve this optimization problem, the problem is decomposed into an energy scheduling optimization subproblem and a RRFU selection optimization subproblem to solve separately.
