RCM-BR: An efficient rate control protocol for multimedia delivery in Wireless Internet

Next Generation Wireless Internet (NGWI) is expected to provide real-time multimedia services like voice and video delivery. It is important to develop an efficient rate control protocol for the transmission of multimedia data over theWireless Internet. Moreover, it is desirable to develop an energy efficient protocol since wireless devices are energy constrained. In this paper an effective rate control protocol for delivering multimedia data over the wireless networks is presented. Simulation results indicate that the proposed rate control mechanism achieves a good throughput performance, smooth rate variation, minimum delay jitter and better energy efficiency. The performance test results obtained over a miniature NGWI test bed validate our proposed rate control mechanism in terms of throughput performance, rate variations, low latency and jitter.
