Abstract

In recent years, cluster-based routing protocols have emerged as a core technology for Wireless Sensor Networks (WSNs), attracting significant attention from researchers. This paper introduces a novel semi-fixed clustering algorithm, SFC-QL-IACO, designed to maintain energy balance in WSNs. The algorithm employs semi-fixed clustering to redistribute cluster nodes for initial load balancing and utilizes Q-Learning and enhanced ant colony optimization to construct data transmission paths. Clusters are dynamically adjusted when the energy difference exceeds a specified threshold to ensure energy balance. A dynamic energy threshold is implemented to prevent network disruptions caused by the depletion of cluster head energy, with cluster head rotation occurring as needed. Simulation results show that SFC-QL-IACO outperforms existing algorithms in terms of energy consumption, load balancing, and network lifetime.

基于q学习的wsn半固定聚类路由算法

近年来，基于集群的路由协议作为无线传感器网络（WSNs）的核心技术，受到了研究人员的广泛关注。本文介绍了一种新的半固定聚类算法SFC-QL-IACO，用于维持无线传感器网络的能量平衡。该算法采用半固定聚类对集群节点进行重新分配，实现初始负载均衡，并利用Q-Learning和增强蚁群优化构建数据传输路径。当能量差超过阈值时，系统会对集群进行动态调整，以保证能量均衡。实现动态能量阈值，防止簇头能量耗尽导致网络中断，簇头根据需要进行旋转。仿真结果表明，SFC-QL-IACO算法在能耗、负载均衡和网络生存时间等方面都优于现有算法。
