This paper presents new distributed power and admission control algorithms for ad-hoc wireless networks in random channel environments. Previous work in this area has focused on distributed control for ad-hoc networks with fixed channels. We show that the algorithms resulting from such formulations do not accurately capture the dynamics of a time-varying channel. Hence, algorithms designed for fixed channels may perform quite poorly in random channels. In order to address these issues, this work proposes new algorithms, based on stochastic approximation, for optimal distributed power and admission control in random channels.
