Gateway Selection Optimization in Hybrid MANET-Satellite Network

In this paper, we study the problem of gateway placement in an hybrid mobile ad hoc – satellite network. We propose a genetic algorithm based approach to solve this multi-criteria optimization problem. The analysis of the proposed algorithm is made by means of simulations. Topology dynamics are also taken into account since the node mobility will impact the gateway placement decisions. Our solution shows promising results and displays unmatched flexibility with respect to the optimization criteria.
