摘　　要：网络拥塞现象在计算机网络中普遍存在,如何改进无线TCP的拥塞性能成为研究热点。利用新的端到端检测作为无线TCP改进方案。在实验中发现IDD值的增长是网络发生拥塞的充要条件。XCP协议通过显式地通告发送端应该增加或降低多大的发送窗口来使各用户流公平共享网络资源,XCP-B来源于XCP,是无线网络中一个很成功的应用。Network congestion can be found everywhere in computer networks. Wireless TCP research,which uses the new end-to-end testing as TCP improvement plan,and it has become important Internet hot research field. The growth of IDD value is the necessary and sufficient condition of network collided, but the congestion control protocol based on explicit feedback will join the network congestion control inside routers. XCP protocol explicitly tells the sending end how large it should increase or reduce the sending window to make the users have their fair share of the cyber source. XCP-B, which came from XCP, is a very successful application of wireless network.
