摘要
无线传感器网络分簇路由协议,通过簇头节点协调簇内节点之间的工作,可以有效的减少能量消耗,提高网络的性能。而LEACH协议是经典的分簇算法,是目前重点研究的路由技术。本文对LEACH协议工作原理进行了分析。在此基础上,详细介绍了使用NS2软件仿真无线传感器网络路由协议LEACH的方法,并以能量消耗和网络生命周期为衡量网络性能的指标,将仿真结果与MTE路由协议进行了对比分析,得出了LEACH协议能有效的降低能耗,延长网络的生命周期。
Through cluster head coordination within the cluster members, clustering router protocol in wireless sensor network can reduce energy dissipation effectively and prolong the network life. LEACH protocol is the classic Clustering Algorithms, which has been the most crucial topics recently. The principle of LEACH is briefly analyzed, the method of simulation LEACH protocol based on NS2 are detailed introduced. At last taking energy consumption and network life cycle as measuring the network performances, the simulation results is presented and analyzed comparing with MTE router protocol, concluded the virtue of cluster protocol LEACH not only reduce energy consumption but also prolong network life.
