Executive Summary

To support rate allocation schemes for wireless ad hoc networks at the MAC layer, a cross-layer MAC protocol is proposed in this paper to coordinate transmissions among flows and guarantee their allocated rates. Two different algorithms are implemented in this protocol: the first one is able to support an arbitrary bandwidth allocation scheme but has a longer convergence time, while the second one is specifically designed for a category of rate allocation schemes and thus have a much better convergence performance.
