An energy based multipath routing method for wireless networks, involving wireless networks. The path discovery method is: the source node to flood the RREQ signaling initiated routing process; intermediate nodes according to the received quality of the link of RREQ signaling and its residual energy information set forward time lag; hysteresis process, if you receive a better path, then update the path information and the lag time of each intermediate node; forwarded only once RREQ signaling; host node to obtain multiple energy path according to RREQ message received. The invention can through on-demand routing path discovery process, a number of energy efficient path, so as to improve the efficiency and reduce the node energy route discovery frequency, reduce protocol overhead and prolong the network lifetime, and is easy to be realized on the basis of the existing wireless node platform.

1.无线网络的基于能量的多路径路由方法,所述的无线网络,具备以下条件:节点采用电池供电;节点是全向天线;节点可以自由移动也可以静止;其特征是:包括路径发现方法、路径维护方法、数据发送和流量分配方法三部分;路径发现方法是:源节点以洪泛RREQ信令方式发起寻径过程;中间节点根据接收到该RREQ信令的链路的质量状况和自身剩余能量信息设置迟滞转发时间;迟滞过程中,如果收到更好的路径,则更新路径信息和迟滞时间;每个中间节点仅转发一次RREQ信令;宿节点根据所收到的RREQ消息获得多条节能路径;路径维护方法和数据发送方法是惯用方法,即在链路中断时,源节点从本地路由表中删除路径,重新寻径;数据发送过程中,每个数据分组携带该分组走过路径的节点列表信息。
