Wireless NUM: Rate and Reliability Tradeoffs in Random Environment

Abstract

We describe Wireless Network Utility Maximization, WNUM, and compare its performance to NUM for wireless networks of interfering links under random time varying channel conditions. WNUM is shown to simultaneously offer greater rate and reliability performance in simulations operating under Rayleigh fading. A general method for finding adaptive network control policies is presented that is sample- based and converges to the optimal control policies for the network.
