摘　　要：针对移动自组网网络生存时间较短、传统按需路由协议开销大且易断裂的问题,文中提出一种移动自组网基于地理位置信息的能量辅助路由协议LEAODV(Location-Energy-AODV)。传统按需距离矢量协议以广播方式进行路由发现,路由开销大且未考虑节点能量耗尽而造成路由断裂问题。LEAODV路由协议考虑通信节点地理位置信息与节点自身能量剩余百分比,引入节点稳定二维前程值和节点能量分级的计算方法。在按需距离矢量协议的基础上,增加稳定二维前程值和能量分级辅助路由,减少路由请求负载,限制低能量节点参与路由,从而提高路由稳定性。在OPNET仿真平台进行仿真,验证LEAODV,TSRAL和AODV的性能。理论分析与仿真实验结果表明,LEAODV协议在保证网络可靠性的基础上比传统按需距离矢量协议算法延长了网络生存时间,降低了网络路由开销,在节点数目较多的网络更具优势。In allusion to the problems that the mobile Ad Hoc network has short lifetimes and the traditional on⁃demand routing protocol has large expense and is easy to break,an energy⁃assisted routing protocol LEAODV(Location⁃Energy⁃AODV)based on geographical location information is proposed for the mobile Ad Hoc network.The traditional on⁃demand distance vector protocol uses broadcast mode for route findingdoesn′t consider the high routing overhead and the node energy depletion that may cause the route fracture.In consideration of both the geographical location information of the communication nodes and the remaining percentage of the energy of the node itself,the LEAODV routing protocol introduces the computing method of the stable two⁃dimensional potential value and node energy classification.On the basis of the on⁃demand distance vector protocol,the assisted routing of the stable two⁃dimensional potential value and energy classification are added to reduce the request load of routing,and restrict low⁃energy nodes to participate in the routing,so as to improve routing stability.The simulation on the OPNET simulation platform is performed,which verifies that the performance of the LEAODV,TSRAL and AODV.The theoretical analysis and simulation experiments show that,in comparison with the traditional on⁃demand distance vector protocol algorithm,the LEAODV protocol extends the network lifetime and reduces the network routing overhead on the basis of ensuring network reliability,and has more advantages in networks with a large number of nodes.
