基于LEACH与蚁群算法的WSN路由机制及性能分析

Performance Analysis of WSN Routing Scheme Based on LEACH and Ant Algorithm

无线传感器网络是实现远程监测的方法之一,由于能量和网络生存时间的限制,其路由协议必须维持较小的路由信息并尽可能的减少能量消耗。在分析经典的分层路由算法LEACH算法特点的基础上,针对较大规模的网络环境将LEACH算法与组合优化蚁群算法相结合,并在NS2环境下验证其性能。仿真结果表明:运用修改后的新路由优化算法,增加了网络中的数据包发送量,分散了网络中传感器节点的能量消耗,延长了网络的生存时间。

Wireless sensor network （WSN） is one of the tools to monitor long distance. Because of the limitations of energy and life-time of network, the routing protocol must maintain smaller routing information, and reduce the energy consuming as much as possible. After analyzing the features of LEACH routing algorithm, we run a new algorithm combined with LEACH algorithm and ant algorithm in a comparatively large network scale, and test the new algorithm＇s performance in NS2. The result of simulation shows that after the application of the new algorithm, the traffic of network has increased, the consuming energy of sensor nodes has been distrib, and the life of the network has been prolonged.
