摘　　要：网络拥塞在分组无线网(PRNET)中是一个潜在的问题,为减轻或避免拥塞的摧毁效应,在PRNET中,有必要对拥塞进行控制。本文首先分析了以往的拥塞控制中存在的问题,然后介绍了两种新的相互合作的拥塞控制技术——建立长期最大—最小端到端流率的端到端拥塞控制算法以及链路层拥塞避免算法,最后对这两种机制的性能进行了相应的分析与评价。Network congestion is a potential problem for packet radio network (PRNET). To eliminate or avoid the desastrous effects of congestion, there is a need to put it under central in PRNET. This paper first analyses the problems existing in the previous congestion control technology, then it introdues two new kinds of cooperating congestion control technology——the end-to-end rated based algorithm which establishs max-min fair resource allocation and the link-layer congestion avoidance algorithm, finally, the paper gives some corresponding performance analysis and evalution for the new technology.
