摘　　要：针对飞行自组网(FANETs)中因节点高速移动导致链路频繁断开的问题,提出一种具备链路生存时间预测与路由自主修复能力的高动态FANETs组播路由协议。根据相邻节点间距离的变化情况预测邻居节点间剩余链路生存时间,同时基于预测结果并结合路由跳数、剩余能量等因素对链路质量作出综合评价,选出最佳中继节点以提高路由的可靠性。此外,通过局部路由修复与全局路由刷新相结合的策略对所建立路由进行动态维护,缓解节点高速移动引起的链路频繁断开问题,提高数据递交率。实验结果表明,在不同场景下,该协议在数据递交率、网络吞吐量、路由开销等方面均优于经典组播路由协议ODMRP。In order to solve the problem of frequent link disconnections caused by high-speed movement of nodes in Flying Ad-hoc Networks(FANETs),a multicast routing protocol that supports link lifetime prediction and autonomous routing repair is proposed for highly dynamic FANETs.The protocol can predict the lifetime of residual links between neighboring nodes according to the changes of the distance between the nodes.Based on the prediction result,the number of routing hops and the residual energy,the link quality is evaluated comprehensively.On this basis,the best relay node is selected to ensure the reliability of the established route.Then the established route is dynamically maintained by using local route repair and global route refreshing,so the frequent link disconnections caused by high-speed movement of nodes can be relieved,improving the delivery rate of data.The experimental results show that the proposed protocol is superior to the classical multicast routing protocol ODMRP in terms of data delivery rate,network throughput and routing overhead in various scenarios.
