WSN中的路由协议改进技术探究

摘要

To prolong the life of the survival of wireless sensor network (WSN), reduce the consumption of energy use, this paper proposes an improved algorithm based on LEACH agreement (LEACH-DE).It is the first to collect data by cluster head, and then the cluster heads to form multiple hops between way to select the optimal path sends the data to the base station. Selection of cluster head nodes can be considered in terms of the residual energy of cluster nodes.Information transmission between cluster head nodes can also be based on energy surplus into cases between nodes.This solved the LEACH protocol cluster head nodes under the heavy load quickly lead to energy consumption problem and improve the network energy consumption balance problems, thereby prolong the survival time of the network.%为延长无线传感器网络的生存寿命，减少能量的消耗使用，本文提出一种改进基于 LEACH 协议的算法（LEACH--DE）。它是首先通过簇头来收集数据，然后这些簇头之间来形成多跳的方式选取最优路径把数据传送到基站。簇头节点的选取可根据簇头节点能量剩余情况来考虑。簇头节点间的信息传递也可根据节点间的能量剩余情况考虑。这样解决了LEACH协议的簇头节点负载过重导致能量快速消耗得问题以及改善网络能量消耗均衡的问题，从而延长网络的生存时间。
