摘　　要：针对水声移动传感器网络中存在水声通信环境恶劣、通信环境复杂多变以及节点能量受限造成的水声移动传感器网络能量不均和路由链路断裂问题,提出一种基于能量与链路度量路由的改进按需平面距离向量路由(AODV)协议.引入了以能量阈值为基准描述网络节点能量状态的能量指标以及以邻居节点间距离为基准描述链路状态的链路指标,并以综合考虑网络路由链路中节点的能量指标、路由链路指标以及路由链路跳数的路由度量作为协议选择路径的优先条件,并以此进行路由修复.仿真实验表明,本文所设计的改进AODV协议可提升网络整体数据量、均衡网络节点能量、延长网络的生存周期.Aiming at the problem of energy imbalance and routing link fracture caused by the poor underwater acoustic communication environment, complex and changeable communication environment and the limited node energy in underwater acoustic mobile sensor network, an improved ad hoc on-demand distance vector routing(AODV) protocol based on the energy and link metric routing is proposed. Introducing an energy index based on the energy threshold describing energy state of network nodes and a link index based on the distance between neighbor nodes describing link state are introduced,and the routing metric taking the energy of network nodes, link index of routing and link hop count into consideration as the priority condition of protocol path selection, and then the route repair is carried out. The simulation results show that the improved AODV protocol designed in this paper can improve the total amount of network data, balance the energy of network nodes and prolong the life cycle of network.
