Performance Evaluation of Joint Transmission Coordinated-MultiPoint in Dense Very High Throughput WLANs Scenario

Abstract : In this paper, we propose to use the Joint Transmission approach of Coordination Multipoint (JT-CoMP) of cellular networks, in order to reduce the interference impact in dense Very High Throughput (VHT) WLANs. VHT WLANs are based on wider channel bandwidth, efficient modulation techniques and support for spatial streams using MIMO schemes. However, the interference problem persists despite these approaches, and thereby prevents mobile stations to fully reaping the capacity improvement of such networks. We consider the stadium dense scenario, where the AP locations are carefully planned to optimize coverage and minimize cell overlap. To study the performance in such deployments, we develop a geometric stochastic model and investigate the benefit of JT-CoMP. Using simulation, we characterize the performance in terms of coverage and throughput for different sizes of coordinated set and carrier sensing domain of access points. Our results show that JT-COMP is an interesting technique for dense networks.
