高效节能的无线传感器网络路由算法

摘要

The position information of wireless sensor network node is very important.However,the general existing location algorithm is not suitable in the bad environment,and the routing algorithm design can directly affect energy consumption of the system.This article proposes one kind of node positioning scheme,and constructs a routing algorithm based on sleep mechanism and minimum cost path.The theoretical analysis and simulation results show that this algorithm has higher energy conservation and can improve the performance of the network.%无线传感器网络中节点的位置信息非常重要,目前通用的定位算法不适合恶劣环境;路由算法的设计直接影响到系统的能量消耗。在此提出一种基于测距的节点定位方案,并构建基于睡眠机制、最小成本路径的节能路由算法,通过理论分析和仿真实验,证明该算法具有较高的节能性,能提高网络的整体性能。
