PSRED: A Queue Management Algorithm with Priority Self-adaptive Random Early Detection for Ad Hoc Network

This paper analyzes the status and shortcomings of the existing queue management algorithms of the Ad Hoc networks and puts forward a queue managemen algorithm with priority self-adaptive random early detection (PSRED). The algorithm can not only avoid the network congestion effectively but also resolve the "starving to death" phenomenon of inferior priority queue. Then the algorithm can make router manage queue more accurately. The simulation shows that the PSRED algorithm can reduce queuing delay and the loss probability of the packets effectively, at the same time the jitter of queue length restricted in a relatively slight range.
