改进的网络路由协议低功耗自适应分簇算法

LEACH(low energy adaptive clustering hierarchy低功耗自适应算法)是无线传感器网络层次型路由协议中最重要和最具代表性的算法之一。通过对经典分簇路由算法LEACH的分析,针对LEACH算法中簇首分布不均匀、簇首与基站之间只能采用单跳路径的缺点,在簇首选择方式、簇首与基站的通信方式两方面进行了改进,并对LEACH算法及改进后的算法进行了仿真试验。仿真结果表明:该算法能有效地降低无线传感器网络节点的能量消耗,延长了网络存活时间,提高了传统LEACH算法的性能。

Improved Low-power Adaptive Clustering Algorithm

LEACH(low energy adaptive clustering hierarchy)is one of the most important and most representative algorithms among hierarchical routing protocols of wireless sensor networks.Aiming at the disadvantages that the cluster head distributed not evenly,and only single-hop path could be used in the LEACH protocol,the selection of cluster heads and the communication between cluster heads and base stations were improved.Simulation results showed that the improved algorithm could efficiently reduce energy consumption of wireless sensor network nodes,and made survival time of network much longer than traditional LEACH algorithm.
