Abstract: Energy efficient routing is an important issue for extending the wireless sensor network lifetime.This work begins with thorough analyses and investigation of existing LEACH protocol.On this basis,an autonomous zone-based multi-hop routing protocol,i.e.AZM-LEACH,is proposed,in which the total energy consumption is optimized,and the energy balance is considered as well.The main idea is to avoid direct(single hop) communication between sink and cluster heads which are far away.Simulation experiments demonstrate that,compared to the LEACH,the proposed AZM-LEACH routing mechanism achieves better performance in terms of node energy consumption and network lifetime.

摘要: 能量高效的多跳路由算法对延长无线传感器网络生命周期具有重要意义。在深入研究LEACH协议的基础上,提出一种均衡节点能耗的分区自治多跳路由改进协议AZM-LEACH。其核心思想是避免离汇聚节点较远的节点与汇聚节点直接通信,从而延长网络生存时间。通过仿真的方法对AZM-LEACH算法进行性能分析与评价。结果表明,AZM-LEACH算法在延长网络生命周期和减少能量消耗方面比LEACH算法有了明显的改善。
