Fast Distributed Rate Control Algorithm with QoS Support in Ad Hoc Networks

Ad Hoc networks are characterized as fast time-varying. Thus, fast distributed algorithm to implement self-management is indispensable, especially for QoS support. In this paper, we propose rate control with QoS support in Ad Hoc networks based on primal-dual interior-point method. We apply Gaussian belief propagation algorithm to compute the Newton step. For implementing distributed computation in practical network, we design the mapping rules between GaBP-mapping network and the practical networks. Finally, the simulation results show that the proposed algorithm has favorable performance, including fast convergence, robustness and scalability.
