摘　　要：由于Ad Hoc网络中的节点可以随处移动,因此网络的拓扑结构也随时变化。目前的路由协议很难满足它的通信需求。设计一种适用于动态环境的实时预测路由方案,用于提高数据传输的效率。综合考虑节点的通信半径与路由的可靠性,判断路由重建时机。在预测到通信路由不可靠时,发出路由更新消息,融合各种指标作为选择新路由的依据,从而提高通信连通的有效率。实验结果表明,对通信链路质量的实时预测既能减小通信时延,也能确保新路由的有效性,采用该协议比其他协议数据传输比率平均提高约5%,最高可达约10%。Since the nodes in the Ad Hoc network can move anywhere,the topology of the network changes at any time.Current routing protocols are difficult to meet its communication needs.We design a real-time predictive routing scheme for dynamic environments to improve the efficiency of data transmission.Comprehensively considering the communication radius and stability of the nodes,the time of route reconstruction was judged.When the communication route was predicted to be unreliable,a routing update message was issued,and various indicators were combined as the basis for selecting a new route,thereby improving the efficiency of communication connectivity.The experimental results show that the real-time prediction of the communication link quality can reduce the communication delay and ensure the validity of the new route.The ratio of data transmission by this protocol is increased by about 5%on average and the maximum increase is about 10%.
