摘要
无线传感器网络(WSN)路由协议中的LEACH协议作为最早提出的层次型协议,得到了广泛的应用与关注。为了达到对比分析低功耗自适应集簇分层型LEACH协议、平面型MTE协议和改进后的LEACH-C协议的目的,利用NS 2网络仿真平台做了仿真实验,分析研究了仿真数据。结果表明以LEACH协议为基础改进后的LEACH-C协议在给定能量条件下,经过一段时间的运行,剩余节点数最多、能耗最小、数据收发量最大,能有效延长网络使用寿命,具备广泛的实际应用价值。
LEACH protocol in wireless sensor networks(WSN) is the first hierarchical routing protocol which is widely used and concerned.In order to reach the goal of analyzing the low energy adaptive clustering hierarchy LEACH,the plane routing protocol MTE and the improved routing protocol LEACH-C protocals,a simulation experiment is conducted by using NS 2 and the simulation data is analyzed.The result of experiment indicates that the improved LEACH-C protocol based on LEACH have the maximum number of residue nodes,the least energy consumption and the maximum quantities of received datas at the original energy after a period of running.It can also prolong the network life and has a practical application value.
