摘　　要：针对无人机自组网多优先级业务并行传输,以及高优先级业务低时延、高可靠服务质量(QoS)需求的问题,提出基于队列优化的多优先级媒体接入控制(MAC)协议。该协议通过多优先级队列优化算法自适应调整不同优先级业务的发送概率和选择发送信道,实现多优先级业务区分服务。仿真结果表明,该协议在重负载情况下可以保证最高优先级业务低时延(小于2 ms)、高可靠性(大于99%)的QoS需求以及系统较高的吞吐量,并且其他优先级业务性能均能保持在一个较高的水平。A multi-priority media access control(MAC)protocol based on queue optimization was proposed to solve the problem of multi-priority services parallel transmission and low latency,high reliability of the high priority service in UAV ad hoc network.In this protocol,the multi-priority queue optimization algorithm was used to adaptively adjust the transmission probability of different priority services and select the transmission channel to achieve multi-priority differentiated services.The simulation results showed that the protocol could effectively guarantee the QoS requirements of the highest priority service with low latency(<2 ms),high reliability(>99%)and high system throughput under heavy load,and the performance of other priority services could be maintained at a high level.
