摘　　要：TCP在无线自组织网络中受到信道竞争和队列拥塞的双重影响,因而不能准确地调节数据发送速率从而降低了传输性能。本文针对该问题提出一种基于对信道竞争和排队拥塞联合检测的TCP速率调制策略。实验结果显示,本策略在吞吐量和端到端时延上均明显提高了TCP的性能。TCP encounters double effects of channel contention and queue congestion when working in the wireless ad hoc network, and thus cannot accurately adjust the data transmission rate, leading to poor transmission performance. Aiming at this problem, this paper propose a TCP rate adaption scheme based on jointing detection of channel contention and queuing congestion. Experimental results show that this scheme significantly improves TCP performance both in throughput and end-to-end delay.
