一种用于无线传感器网络的改进SPIN路由协议

由于无线传感器网络（WSN）节点的能量有限,因此尽量减少各节点的能量消耗,延长整个网络的生命周期,是无线传感器网络路由协议设计中考虑的主要问题。文章提出了一种改进的SPIN路由协议,取名为SPIN-Z,与现有的SPIN协议比较,其主要特点是通过减少整个网络冗余数据的传输来减少能量消耗。在NS2环境下进行仿真,结果表明SPIN-Z协议比SPIN协议更加节省能量。

An Improved SPIN Routing Protocol for Wireless Sensor Networks

Because of the limited energy of wireless sensor network(WSN)nodes,the major consideration of designing routing protocol is to reduce the energy consumption of each node and extend the lifetime of the network.This paper presents an improved SPIN routing protocol,which is named for SPIN-Z.Comparing with the existing SPIN protocol,the SPIN-Z protocol has an advantage which is reducing the transmission of redundant data to save the entire network’s energy.In NS2 simulation,results show that the SPIN-Z protocol consume less energy than SPIN protocol.
