Utility Optimization in Heterogeneous Networks Via CSMA-Based Algorithms

We consider utility optimization in a wireless data system, where transmission can happen from multiple transmitters on multiple carriers at multiple rates. We build upon the CSMA-based (carrier sense multi access) framework in cite{LiuYPCP10}, which considers a similar but simpler setting of single carrier and single rate. We show that the CSMA-based algorithm also optimally solves utility optimization under this generalization.
