摘要

摘要: 针对航空自组织网络的高动态特性和对高优先级业务的服务质量(QoS)要求,提出了一种无反馈介质访问控制(MAC)协议建模方法及相应的阈值设置方法,以保证高优先级数据分组的时效性及可靠性。首先,对数据分组在接收端碰撞建立时间约束模型,得到信道统计结果与分组成功概率的映射关系;然后,根据不同业务的QoS要求设置接入阈值;最后,实现对不同优先级业务的接入控制。仿真结果表明,在典型空域网络场景下,基于该建模方法的无反馈MAC协议可以为高优先级业务提供QoS保证,即分组成功概率大于99%,端到端延时小于1 ms。

Abstract: In aeronautical Ad Hoc networks,in order to meet the strict quality of service (QoS) requirements of high priority traffic with high dynamics,a modeling method and a corresponding threshold setting method for priority feedback-free media access control (MAC) protocols were proposed to guarante etimeliness and reliability of high priority packets.First,a time constraint model was built at receiving end,with a mapping relation between channel statistics and packet success probability being deduced.Accordingly,the access threshold basedon QoS requirements of different traffic was obtained,while access control of different traffic was accomplished.Simulation results indicate that,in typical aeronautical networks,the QoS requirements of high priority traffic can be guaranteed as the feedback-free MAC based on the proposed method is employed.In particular,packet success probability of high priority traffic is higher than 99%,and end-to-end delay is less than 1 ms.
