无线传感器网络节能路由协议研究

Research on Energy Saving Routing Protocol in Wireless Sensor Networks

目前,在环境监测、农业、军事领域广泛使用无线传感器网络(WSN)。对于网络性能来说,存在限制的就是节点能量的限制,所以,加强WSN路由协议节能特征,是延长网络运行周期的关键,完善WSN性能也成为当今主要研究问题。使用NS2仿真软件,演示改进前后的LEACH协议和多种路由协议,探讨改进后的LEACH协议特性,满足网络负载需求,延长第一个死亡节点时间。

At present,the wireless sensor network（WSN）is widely used in environmental monitoring,agriculture and military.The disadvantage of the WNS is the limitation of the energy of nodes.Therefore,strengthening the energy saving characteristics of WSN routing protocol is the key to prolong the network operation cycle,and improving the performance of WSN has become the main research problem.This paper uses NS2 simulation software to demonstrate the LEACH protocol and various routing protocols before and after improvement.The improved LEACH protocol is mainly discussed to meet the network load demand and prolong the first death node time.
