Abstract :
The UDP transport protocol has been fore selected for the most of multimedia traffic transport on mobile wireless networks. Nevertheless, it exhibits some problems related to bandwidth sharing between several traffic sources, as well as TCP friendliness with established TCP connections on the network. In this paper, we propose a combined mechanism, the PRDR: proportional and derivative algorithm for UDP traffic congestion control relying on the buffer occupancy to compute the supported rate by a router on the connection path. The information is carried back to the traffic source to adapt its actual transmission rate to the network conditions. The PRDR algorithm can be implemented at the transport layer in the base station in order to insure a fair share of the 802.11 bandwidth between the different UDP-based flows.
