摘要:
无线传感器网络路由协议设计的主要目标就是尽可能高效地利用传感器节点能量来延长无线传感器网络的生存时间。文中分析了经典的分层路由协议-Leach协议,对选择簇头的门限值进行了重新定义,考虑了传感器节点剩余能量和此节点最近未当选为簇头的轮数,并对每个簇内成员的数量进行了限制,为进一步节省能量消耗在簇头到基站之间还使用了多跳通信。 Matlab仿真结果表明,改进的路由协议比Leach协议更有效地利用无线传感器网络传感器节点的能量,延长了网络的生存时间
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
