Observing that simplicity implies efficiency and scalability, this paper proposes a position-based deployment and routing strategy, and then gives a concrete approach under this strategy, for the emerging wireless mesh networks with multiple radios and directional antennas. The main idea of this strategy is to deploy the mesh network in certain kind of geometric graph and then design a position-based routing protocol by exploiting the routing properties of this graph. The proposed concrete approach comprises two parts: (1) a topology generation algorithm based on Delaunay triangulations and (2) a routing protocol based on the greedy forwarding algorithm. Both parts have appealing properties for deployment or routing, with formal proofs provided when applicable. Our simulation results strongly support this proposed approach.
