无线传感器网络中一种改进的Leach协议
An Improved Leach Protocol in Wireless Sensor Networks
摘要
Abstract
Wireless sensor network routing protocol is to prolong the survival time of wireless sensor networks by using the sensor nodes energy efficiently. In this paper analyze the classical hierarchical routing protocol-Leach,redefine the threshold in the cluster head selec-tion,consider the residual energy of the sensor node and the number of rounds the present node not selected as cluster head,limit the num-ber of members for each cluster,and use multi-hop communication between the base station and cluster heads. Matlab simulation results show that the improved routing protocol can make more efficient use of the energy of sensor nodes than Leach protocol,extending the net-work lifetime.关键词
