高丢包率和有限带宽是无线传输系统的主要特点，同时也是决定无线多媒体网络设计成败的关键因素.提出一种适用于无线网络的可扩展拥塞控制算法(scalable congestion control algorithm for wireless networks,SCCW)，该算法可以在无线网络中使用多个业务流,且在拥塞丢包和随机丢包共存的情况下，具有很好的可扩展性.仿真结果表明，该算法比非可扩展性拥塞控制算法，如加法增加乘法减少（additive increase multiplicative decrease,AIMD)、平方根计算（square root calculations,SQRT）、倒数增减加性减小(inverse increase additive decrease, IIAD)等，具有更低的数据丢包率.

 High packet loss rate and limited bandwidth are two features that present the biggest challenges in successful design of multimedia wireless networks. A scalable congestion control algorithm for wireless networks (SCCW) is proposed in this paper. The technique has excellent scalability when a large number of flows are used, and when random and congestion losses coexist in a wireless network. Simulation results show that SCCW has better performance than additive increase multiplicative decrease (AIMD) algorithm, square root calculations (SQRT) algorithm, and inverse increase additive decrease (IIAD) algorithm.
