Cross-layer design for multihop manets utility optimization with AQM

We study the problem of jointly solving the contention and congestion distributed control problem in a bounded queue multihop mobile ad-hoc networks. Unlike the majority of the published work in this area, we focus on the feasibility of the proposed solution in case of random static and dynamic networks considering the signaling and overheads. 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 suboptimal results. In this paper, we combine a specific network utility maximization problem with a simple and efficient Active Queue Management (AQM) mechanism that we believe is appropriate for mobile ad-hoc networks. Using IEEE 802.11 protocol as MAC layer protocol, we show via NS-3 simulations that the proposed Cross-Layer Design (CLD) significantly outperforms standard protocols such as TFRC in static and dynamic networks
