摘　　要：本文分析了Ad Hoc网络中队列管理算法的研究现状,讨论了不同算法采取的策略在拥塞控制、丢弃数据包、队列长度抖动、公平性等方面的优点和不足。本文基于队列优先级自适应的思想提出了PSRED算法,实验仿真结果表明该算法在排队延迟、丢包率、队列长度抖动等性能评估优于其它算法。We analyze the research status of the queue management algorithms in the Ad Hoc network and discuss advantages and shortcomings of different algorithms in network congestion, the loss of the packets, the jitter of queue length and fairness. Based on the idea of priority self-adaptive, we propose a priority self-adaptive random early detection （PSRED） queue management algorithm. The results of the simulation show that the performance of the algorithm is superior to other algorithms in queuing delay, the loss probability of the packets, the jitter of queue length, etc.
