Spatial reuse in IEEE 802.16 based wireless mesh networks

Abstract

The IEEE Standard 802.16 supports for creating wireless mesh networks. The primary advantage of mesh networks is an improvement of capacity by concurrent transmission in the wireless environment. Therefore, the degree of spatial reuse is very crucial to realize the full potential of such wireless mesh networks. In this paper, we investigate the spatial reuse in IEEE 802.16 mesh networks. We propose a scheduling mechanism and a routing algorithm taking into account the interference in wireless environment to achieve maximum spatial reuse hence to increase the overall network throughput. The simulation results show that the proposed schemes achieve significant improvement and are more effective.
