基于物联网的无线传感器网络路由协议研究

摘要

针对无线传感器网络中的高效能路由协议问题进行研究，详细分析了传统的分层路由协议 LEACH(低功耗自适应集簇分层)的簇首选取原则和成簇算法，并指出该算法存在的局限性。针对簇首节点的位置不同，提出了簇首间进行多跳中继转发的改进算法，并对此算法进行了仿真实验，结果证明，改进算法的网络生存时间要优于传统的 LEACH 算法。%This paper studies the highly efficient routing protocols in wireless sensor networks and analyzes in detail the rule of cluster head selection for a classical hierarchical routing protocol,i.e.Low Energy Adaptive Clustering Hierarchy (LEACH) protocol and the clustering algorithm and points out the limitation of this algorithm.In view of the different cluster head node positions,it presents an improved algorithm for the multi-hop relay transfers between the cluster heads.Simulation results prove that the network survival time in this improved algorithm is better than that in the LEACH algorithm.
