摘要
简要回顾了传统的LEACH(Low Energy Adaptive Clustering Hierarchy)协议思想,本文提出改进措施:主要是使用新的策略,即利用路由选择转发函数来确定多跳路径中下一跳-Multi-top LEACH协议.通过NS2模拟证明使用该算法系统的生命周期增长,可延长网络的使用寿命.
Starting from the basic idea of classical LEACH ( Low Energy Adaptive Clustering Hierarch) protocol, this paper introduces some innovations : mainly use a new strategy, get the next top of multi-top routes by virtue of transmit function in the routing algorithm-Muhi-top LEACH protocol. The simulation results show that Multi-top LEACH protocol can gain improvement in system's lifecycle, prolong network's lifetime through NS2 simulator.
