Abstract :
Relying on a design-space oriented cross-layer optimization approach, we develop joint TCP congestion control and CSMA scheduling schemes for mobile applications over Internet with distributed multi-hop wireless links. Different from the existing solutions, the proposed schemes can be asynchronously implemented without message passing among network nodes. Confined to the design space of TCP and CSMA, they are readily deployed with current Internet infrastructure. Moreover, global convergence/stability of the proposed schemes to optimal equilibrium is established by using the Lyapunov method in an idealized network fluid model. Simulation results are provided to evaluate the proposed schemes in practical networks.
