摘　　要：Ad hoc网络是一种对等式网络，使用无线通信技术，节点可移动。Ad hoc网络拓扑的频繁变化导致了分组的大量丢失，会被TCP认为是网络发生拥塞，不正确的引发拥塞控制，从而引起吞吐量的急剧下降。使用基于反馈的体系结构与显式的报文通知机制可以有效地克服这一问题。对已有的方法进行比较研究。Ad hoc networks are completely wireless networks of mobile hosts, in which the topology rapidly changes due to the movement of mobile hosts. TCP may misinterpret the packet loss resulting from the topology changes as congestion and invoke congestion control, leading to loss of throughput. A feedback scheme and explicit notification can overcome efficiently this problem. Study and comparisons of several proposed schemes are conducted.
