基于OMNET＋＋leach协议的仿真与改进

摘要

由于无线传感网络是一种能量和资源都有限的网络，为了更好的延长无线传感网络的生命周期，本文对无线传感网络路由协议中的leach协议进行了深入的分析，探讨和仿真。并在这个协议的基础上，对簇头的选择提出了改进。在OMENT＋＋平台上进行了多次的仿真测试，对不同的基站位置这个参数进行了仿真且对比。通过仿真对比发现，新改进的LEACH协议能够很好降低功耗，延长网络寿命，达到了设计的要求。%Because of wireless sensor network is a kind of energy and resources are limited network, In order to prolong the network life cycle .in this paper, According to one of the wireless sensor network-leach protocol do further analysis, probe into and simulation. And in this agreement, on the basis of the choice of cluster head improvement were put forward. The simulation test has carried on OMENT++ platform many times, do the simulation and comparison to the different parameters , for example, the different base station position. Through the simulation contrast found that new and improved LEACH agreement can be very good reduce power consumption, prolong the network life ,and can achieve the design requirement.
