TL;DRAbstract

A new approach, named TCP-I 2 NC, is proposed to improve the interaction between network coding and TCP and maximize the network utility in interference-free multi-radio multi-channel wireless mesh networks. It is grounded on a NUM formulation, and this NUM problem is decomposed into a rate control problem and a packet scheduling problem. The solutions to these two problems perform resource allocation among different flows. Simulations demonstrate that TCP-I 2 NC derives a significant throughput gain and a small delay jitter Network resource is fairly allocated via the solution to the NUM problem and the whole system also runs stably. Moreover, TCP-I 2 NC is compatible with traditional TCP variants.
