基于LEACH协议的簇头优化协议研究

Optimized cluster head protocol of research based on LEACH

针对无线传感器网络的特点,在研究LEACH协议的基础上,提出了一种新的优化的分簇多跳算法。该算法使用能量因子修正了LEACH协议中的的阈值,产生簇头。再将选好的簇头以距离最短为原则生成一条基站到各簇头的链,采集的数据在簇头融合后按生成的链以多跳的方式提交给基站。MATLAB仿真结果显示,该协议能有效地延长网络的稳定期。

According to the characteristics of the wireless sensor network, on the basis of the research of LEACH, this paper puts forward a new protocol multi-hop clustering algorithm. The algorithm uses energy factor to fix the threshold value of LEACH, and produce the cluster head. Then the shortest distance principle is used to make a chain from base station to cluster head, the mixing data in cluster head is submitted to base station in the way of muhi-hop by chain. MATLAB simulation shows that the improved protocol can effectively prolong the stable time of network.
