摘　　要：针对航空自组网频繁的拓扑变化、网络断开的问题,提出一种考虑优先级的逐跳路由(priority concern hop-by-hop routing,PCHHR)协议。PCHHR依据运动方向优先、距离次之的原则选择下一跳路由节点,优先选择向目的节点运动的邻居作为下一跳节点,次优选择距离目的节点最近的邻居作为下一跳节点;区分数据报文的时延需求,优先转发时延约束小的数据。仿真结果表明,PCHHR在较低的控制开销和端到端时延下,总体数据分组投递率高于航空路由协议(aeronautical routing protocol,Aero RP)、贪婪转发路由和传统的端到端路由协议,提高了高实时性数据分组的投递率。Considering the problem of frequent topology change and intermittent connection between nodes in aeronautical Ad hoc networks,this paper proposed a PCHHR. According to the principle of motion direction first and distance second,PCHHR preferentially selected the neighbor node moving to the destination and suboptimally selected the neighbor closest to the destination as the next hop node. Differentiating the delay requirement of data packets,packets with small delay constraints were preferentially forwarded. The simulation results illustrate that PCHHR obtains a higher overall packet delivery ratio than AeroRP,greedy forwarding routing protocol and traditional end-to-end routing protocol under lower control overhead and endto-end delay. Besides,PCHHR achieves an even higher delivery ratio for high-real-time data packets.
