Distributed Cross-layer Optimization in Stochastic Multi-hop Wireless Networks with Cooperative Communications

<04> This is the first work that combines Wornell (MIT)'s work on Cooperative wireless networks with Neely (USC)'s stochastic optimisation to provide cross-layer optimization for multi-hop wireless cooperative networks. It outperforms Yi and Chiang (Princeton)'s seminal utility maximization approach, by jointly optimising: flow control, cooperative scheduling and routing. Simulation results verify our theoretical analysis and reveal significant gains, in terms of throughput, flexibility, and scalability. Cooperative communication is still very much in its infancy but will fundamentally change wireless networking, our work is the first distributed approach to optimising such systems thus providing a practical and salable solution.
