Abstract

This work presents the design and preliminary performance evaluation of a new congestion control mechanism for multimedia applications over wireless networks: the Wireless Proportional and Derivative Algorithm (W-PRDR). W-PRDR is based on the exchange of RTCP reports to feed the sources with the supported rate so that they can adapt their transmission rate according to the loss state and the allowed fair share bandwidth in the network. In order to fit to a wireless environment, we enhanced the original PRDR algorithm with a loss discrimination scheme to distinguish between congestion losses and random errors due to wireless transmission. We show through simulation the capacity of the W-PRDR mechanism to improve the transmission rate under different simulated network topologies.
