In this paper, we study the problem of jointly solving the contention and congestion distributed control problem in a bounded queue wireless ad-hoc network. The resulting flow rates satisfy fairness criteria according to a given Network Utility Maximization (NUM) function. In recent years a number of papers have presented solutions to this problem that are based on network utility maximization algorithms. However, this work typically necessitates either complex computations, heavy signaling/control overhead, and/or approximated sub-optimal results. In this paper, we combine a specific network utility maximization problem with a simple and efficient queue management mechanism that we believe is appropriate for wireless ad-hoc networks. We employ and adapt the IEEE 802.11 protocol to work with the utility maximization algorithm for contention optimization. Finally, we show via NS-3 simulations that the proposed Cross-Layer Design (CLD) significantly outperforms standard protocols such as TFRC.
