基于能量感知的无线传感器网络机会路由方法技术

本发明专利技术揭示了一种基于能量感知的无线传感器网络机会路由方法，属于无线网络协议技术领域。具体方法是在无线传感器网络中，当有数据传输需要时，首先建立一条源到目的的最短路径。之后，节点会将其自身的邻节点集与其在最短路径上的下两跳节点的邻节点集的交集中的节点作为本次数据发送的备选转发节点。然后以备选集中各节点的能量情况来确定节点转发数据包的优先级，继而通过MAC层基于RTS-CTS的控制包应答方式对备选节点进行协调，完成数据传输。本发明专利技术主要用于在数据传输过程中使能量较充沛的节点成为下一跳节点，从而达到均衡全网能量消耗的目的。

Energy aware opportunistic routing in Wireless Sensor Networks

The invention discloses a wireless sensor network opportunistic routing method based on energy perception, belonging to the wireless network protocol technology field. The specific method is that in wireless sensor networks, when data transmission is needed, a shortest path from source to destination is first established. After that, the node will be its own neighbor node set, and its nodes in the intersection of the next two hop nodes on the shortest path will be the alternate forwarding node for the data transmission. Then, the priority of node forwarding packets is determined by the energy situation of each node in the alternative cluster, and then the candidate nodes are coordinated by the MAC layer based on the RTS-CTS control packet response mode to complete the data transmission. The invention is mainly used to make the nodes with more abundant energy become the next hop node in the data transmission process, so as to achieve the purpose of balancing the energy consumption of the whole network.
