摘要
LEACH是最早的无线传感器网络路由协议之一,其组网过程中的推选群首的算法存在着群首个数和群首位置分布不稳定的现象,对网络寿命会产生不良影响。本文提出了撤销群首算法和增选群首算法,通过调整群首数目和群首间距离,达到使群首个数和分布位置趋于稳定的目的,仿真结果证明了算法的有效性。
LEACH protocol is one of the earliest hierarchical sensor network protocols. The number and position distribution of cluster heads generated by its cluster head election algorithms are unstable. This will reduce the lifetime of the networks. In this paper, we propose algorithm of dismissing cluster head and algorithm of complementing cluster head. With these algorithms, the number and position distribution of cluster heads are more stable. Simulation shows the efficiency of the algorithm.
