Directional antennas provide many advantages such as higher gain, increased capacity, longer range, and reduced interference by concentrating radio signal energy in one direction. This paper addresses concurrent transmission scheduling in wireless personal or local area networks deployed with directional antennas. In typical network deployment scenarios, it is quite likely to have non-uniform node densities and traffic demands in various parts of the network. In such situations, to provide load-based service to various parts of the network while aiming to maximize the spatial reuse, this paper proposes a zone-based concurrent data transmission scheduling method. Simulation results show that the proposed method can support a larger number of flows while satisfying a greater fraction of the traffic demands from highly loaded regions, compared to existing methods. |
