Delay bound capacity analysis of dense WLANs
(English)Manuscript (preprint) (Other academic)
Indoor WLAN deployments are becoming denser such that it is fairly common to observe several WLANs operating on the same channel. Increasing density creates more congestion and interference on these WLANs, which potentially has a significant impact on the delay and throughput performance of these WLANs. Therefore, we investigate the behavior of MAC layer delay and aggregate throughput in densely deployed WLANs in connection with different traffic arrival rates, propagation environments and deployment choices. The novelty of this work is that such a comprehensive study has not been performed before. We perform an extensive simulation study using OPNET by incorporating in our analysis a realistic MAC model and the impact of indoor propagation environment causing hidden nodes. We identify the relationship between delay and aggregate throughput in a system of densely deployed WLANs and propose guidelines for determining suitable WLAN deployment densities in different propagation environments.
