Abstract : A substitution network is a rapidly deployable wireless network that provides a backup solution to quickly react to failures on an existing network. We consider a substitution network scenario where wireless routers are equipped with several Wi-Fi cards. The problem addressed in this paper deals with the channel assignment of these wireless interfaces. In this particular context, it is possible to derive an objective function that estimates precisely the overall throughput that can be achieved. This problem is formulated through a linear optimization problem for which we propose a heuristics. Solutions give the channel assignments but also the optimal traffic load sharing between the different paths of the substitution network. Simulation results, performed with ns-3, compare our heuristics to the optimum and to classical approaches.
