Abstract (EN)
Recently, the directional antenna has received intensive research due to its variety of potential benefits for wireless communication systems, especially in the context of ad hoc networks. Nodes equipped with this type of antennas can communicate simultaneously without interference, and potentially establish links between them with less routing hops. This interference reduction provide a higher channel reuse leading to better resource exploitation and potentially better performance. In this study we want to take the advantage of directional antennas by proposing a sectorial coverage in a deployment of a WMN backbone based on mesh mode. Mainly, we propose a new architecture based on this type of antennas and OLSR protocol is used as routing protocol. We show by simulations under NS3 that the proposed architecture improve the overall QoS. We propose also an implementation of this type of antennas and we show with numerical results that the use of directional coverage outperform the omnidirectional coverage.
