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。

Abstract: 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.
