Finding repeater placement for P2P wireless links with NLOS in extremely mountainous regions


A backhaul network consisting of p2p microwave links is the most cost-effective solution for rural Internet access, however, it can be a challenging design because the extreme mountainous geographical conditions make the links have Non- line out sight (NLOS) and be necessary the use of repeaters. Many relays can be implemented to overcome this difficulty. To the best of my knowledge, it does not exist an approach to finding the suboptimal repeaters placement in a computational way. This paper proposes the form to construct a cost function that represents the problem described before, and a genetic algorithm is implemented to find its local minimum at different scenarios.
