多Sink无线传感器网络鲁棒路由协议

针对多Sink无线传感器网络中由Sink节点失效引起的局部数据拥塞，进而导致网络鲁棒性减弱的问题，提出基于侦听机制和模糊控制的多Sink无线传感器网络鲁棒路由协议．该协议采用侦听机制．建立并维护多维树状拓扑路由，避免了采用泛洪方式组网而造成的资源浪费；加入以负载、丢包和跳数为目标的模糊控制算法，进行路由选择，均衡了网络负载．仿真结果表明，该路由协议在一定程度上缓解了网络中Sink节点失效造成的大量丢包以及数据拥塞问题．增强了网路的鲁棒性．

Robustness Routing Protocol in Multi-Sink Wireless Sensor Networks

According to Sink node＇s death problem in Multi-Sink wireless sensor networks, the paper proposes a nov- el routing protocol for Multi-Sink wireless sensor networks based on listening mechanism and fuzzy control algorithm. The proposed protocol is as following： Listening mechanism employed to establish and maintain multi-dimensional tree routing topology;with hops, packet losses and load as targets, a fuzzy control algorithm is proposed. The simula- tion results showed that the performance of the proposed protocol is better than the routing protocol of minimum hop numbers for mitigating packet losses and congestion, and enhancing the robustness of the network.
