摘　　要：无线传感器网络在实时应用中存在节点能量有限、数据传播延时大等问题。为此,提出一种改进的SPIN路由协议。通过比较最小跳数的数目控制数据的传播方向,选择一条到达Sink节点实时性能最优的路径。仿真结果显示,改进协议可以减少传输过程中数据包的数量,降低网络能耗,延长网络生命周期。There are some problems such as limited node energy and propagation delay of data when Wireless Sensor Network（WSN） is used in real-time applications.This paper proposes an improved routing protocol based on SPIN protocol.By comparing minimum number of hops,it controls propagation direction of data,and chooses a path with the best real-time performance to Sink.Simulation results show that the improved protocol can reduce the network energy consumption by reducing data packets in transmission,so that the network life cycle is extended.
