Abstract:

 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.

Key words: wireless transmission system; congestion control algorithm; scalable congestion control algorithm for wireless networks（SCCW）
