摘　　要：具有移动sink的无线传感器网络(WSN)比静态sink具有更长的网络寿命和更好的数据传输性能,但是因为其移动性导致能耗开销巨大,针对这个问题,提出一种基于移动sink的无线传感器网络海星路由协议,灵感来自海星的水脉系统.该路由协议构建了一个带有中心环通道的路由骨干网,并且网络上的径向通道很少.给定网络能动态确定径向通道的数量和环通道的半径,以便减少从源到sink的通信等待时间.实验结果表明,该文海星路由协议能够有效地均衡节点的能量消耗,在数据传输延迟和网络生命周期方面,性能评估的结果优于现有其他协议.Wireless sensor networks with mobile sink have longer network life and better data transmission performance than static sink, but their mobility leads to huge energy consumption. In order to solve this problem, a starfish routing protocol based on mobile sink has been proposed in this paper, which is inspired by starfish water pulse system. The routing protocol constructs a routing backbone network with a central ring channel, and there are few radial channels on the network. The number of radial channels and the radius of the ring channel can be dynamically determined for a given network to reduce the communication waiting time from the source to the sink. The experimental results show that the starfish protocol can effectively balance the energy consumption of nodes, and the performance evaluation results are better than other existing protocols in terms of data transmission delay and network life cycle.
