Here, 5G networks offer high data rates with ultra-low latency and robust reliability, which is essential for managing the substantial data volumes generated by IoT devices in 5G WSNs. IoT needs an optimal communication network to transmit data among different devices. The whole network is categorized as heterogeneous clusters in clustering. The cluster head (CH) selection achieves proficient data communication to the sink node through the chosen CH. In this manuscript, an energy-efficient communication using auto-associative polynomial convolutional neural network in 5G WSN (EEC-HAPCNN) is proposed for improved data transmission through the selected route. Initially, clustering is done by parallel adaptive canopy k-means clustering (PaC-k-M) algorithm. Then, Tasmanian devil optimization algorithm (TDOA) selects the CH required for facilitating the high capacity and low latency features of 5G. The data are given to sink node through the selected CH utilizing hierarchical auto-associative polynomial convolutional neural network (HAPCNN) for efficient routing in 5G wireless communication network. The proposed EEC-HAPCNN method is implemented in NS-3 (network simulator 3). The proposed approach is examined using performance metrics like throughput, energy consumption, network lifetime, and number of nodes alive. The proposed EEC-HAPCNN method provides 17.45%, 17.63%, and 18.43% lesser energy consumption and 17.64%, 17.64%, 18.54%, and 19.33% greater network life time compared with existing DBN-MRFO-5G-WSN, IDCNN-t-DSBO, DACP-WSN-ANN, EEO-IWSN-ML, and EECA-ML-WSN techniques.</p>\u0000 </div>","PeriodicalId":13946,"journal":{"name":"International Journal of Communication Systems","volume":"38 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116625","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}

However, WSNs face significant challenges related to limited battery life and the need for efficient energy management, which can impact their performance and longevity. Traditional routing protocols often fail to adapt to dynamically changing conditions and energy constraints inherent in WSNs, necessitating innovative approaches to enhance energy efficiency and network longevity. This paper introduces a federated learning–based adaptive routing (FLAR) model designed to address these issues by integrating federated learning with adaptive routing protocols. The primary aim of this research is to optimize energy utilization across the network and extend the operational lifespan of WSNs. The novelty of the proposed FLAR model lies in its unique combination of energy-aware participant selection (EaPS), adaptive model compression (AMC), and dynamic data sampling (DDS), which collectively enhance energy efficiency and adapt dynamically to changing network environments. The FLAR model was simulated and analyzed using Network Simulator 2 (NS2) under various network conditions and node densities. The results demonstrate that the FLAR model significantly outperforms traditional protocols by reducing energy consumption by up to 30% and enhancing network longevity by approximately 25%. Additionally, the proposed methodology improves packet delivery ratio and reduces latency, making it a robust solution for sustainable WSN deployment. Overall, the FLAR model offers a significant advancement in WSN technology by effectively managing energy resources and dynamically adapting to network changes.</p>\u0000 </div>","PeriodicalId":13946,"journal":{"name":"International Journal of Communication Systems","volume":"38 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115200","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}

IoT devices in IoT networks collect data from their surroundings and send it in bursts to a server in a remote location. The quantity of applications using computer networks causes resource competition, which in turn causes congestion. The most difficult task in enhancing network quality of service (QoS) is IoT congestion control. For IoT items with modest resource requirements, various protocols have arisen. Different shortages and issues affect basic congestion control, which increases bandwidth use, data loss, and delay. Thus, to solve this issue, in this paper, we propose a bio-inspired fuzzy inference system (FIS)–based constrained application protocol (BIFIS-CoAP) for avoiding congestion over network. In order to determine the level of congestion, we use the bottleneck bandwidth gradient (BG-gradient) and round-trip time gradient (RT-gradient) as inputs for BIFIS-CoAP. By using this indication, BIFIS-CoAP may anticipate impending congestion and alter the sending rate to prevent it. In order to achieve high performance for burst data transfer, BIFIS-CoAP constantly checks for bandwidth that is available and uses the congestion degree for updating the variable retransmission time out (RTO) for retransmissions. Using the adaptive Tasmanian devil optimization method (ATDO), input parameters like the RT-gradient and BG-gradient are modified to enhance the performance of the FIS. Numerous simulation studies have shown that BIFIS-CoAP is feasible, and the simulation results show that it performs better than basic CoAP and fuzzy CoAP in terms of delay, throughput, delivery ratio, and retransmissions.</p>\u0000 </div>","PeriodicalId":13946,"journal":{"name":"International Journal of Communication Systems","volume":"38 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115724","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}

Among the main challenges in V2X network slicing is proposing an appropriate resource management approach that allows resources to be used efficiently while protecting the isolation between slices. One of the benchmarking resource management approaches is the static allocation that provides a full isolation between the slices. This static allocation has serious limitations when dealing with dynamic scenarios, particularly when some slices are overloaded. This paper proposes a deep Q-learning approach to readjust static resource allocation by enabling an opportunistic sharing mechanism in case there is an overloaded slice in the system. More specifically, the main idea of our proposal is to extract an appropriate amount of resources from each available slice within the same infrastructure when receiving rejected connection requests from overloaded slices, while taking into account the isolation aspect of the slicing environment. Simulation results showed better performance in terms of maximizing the use of resources, reducing the probability of new calls being blocked and the probability of handover dropping in the system, while maintaining high isolation compared with other solutions.</p>\u0000 </div>","PeriodicalId":13946,"journal":{"name":"International Journal of Communication Systems","volume":"38 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115726","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}

In a DC bias switching circuit with a combination of eight SMD PIN diodes and two parasitic elements, the antenna's radiation patterns can be shaped to concentrate energy in an omnidirectional radiation pattern. The introduction of switches using an SMD PIN diode at the arms of the driver element produces two switchable frequencies at 915 MHz and 2.45 GHz.
