无线网中面向TCP友好的拥塞控制算法

在LDA协议的基础上，提出一种改进的端到端无线网TCP友好拥塞控制算法（WIAD＋）。WLDA＋根据无线中的拥塞用一种类似于处于丢包和延迟状态的TCP连接的方式来调节发送者的传输行为。考虑到无线网的特殊性，WLDA＋加进了错误区分模式来监测无线网中丢包。通过模拟实验评价了WLDA＋模式的性能。实验结果表明应用错误区分模式能有效地达到无线网的拥塞控制。

TCP-friendly Congestion Control over Wireless Networks

An end-to-end adaptation scheme, called the wireless loss-delay based adaptation algorithm (WLDA+is presented). WLDA+ adapts the transmission behavior of multimedia senders in accordance with the network congestion state in wireless environments. WLDA+ is based on the loss-delay based adaptation scheme which adjusts the transmission behavior of the senders in a manner similar to TCP connections suffering from equal losses and delays. To take the specific characteristics of wireless links into account, WLDA+ incorporates error differentiation schemes to detect the loss nature in the wireless channel. The performance of WLDA+ is then investigated by simulating the behavior of this algorithm under different network to pologies.
