Abstract
Congestion control of a variable bit-rate video stream over the wireless link is critical issue to assure the quality of the received video. If congestion occurs it leads to the buffer overflows which in turn results in packet loss in the networks. In order to overcome this issue, an Optimized Multimedia Streaming and Congestion Control technique for WLAN-3G Network is proposed. In this study, a two-tier integrated heterogeneous wireless network including WLAN and 3G cellular are considered. The streaming rate is estimated by using Fuzzy Logic congestion (FLC) controller. The Congestion level determination unit determines the congestion level and the rate of change of congestion level based on the inter packet gaps which are taken as input to the FLC. Based on the output of FLC, new streaming rate is estimated. The application adjusts to the new streaming rate in order to maintain the buffer level. Also, the threshold value for buffer level is optimized by using the Greedy Streaming to Threshold and Stop (GSTS) algorithm in order to reduce the streaming monetary cost.
