In this thesis, we address the joint routing and slot assignment problem between the routers and the gateways in a radio mesh access networks. We model the problem as a RoundWeighting Problem (RWP) in which the objective is to minimize the overall period of slot activations providing enough capacity to satisfy the bandwidth requirements of the routers. Solving the full problem means generating ...
