Throughput analysis in high density WLANs

Abstract

This letter proposes a simple but accurate approximation to analytically model both the inter-wireless local area networks (WLANs) interactions and the negative effect of collisions in the performance of high density WLAN scenarios. Inter-WLANs interactions are characterized using a continuous time Markov chain (CTMC) model, where states represent the set of active WLANs at a given time. Then, the effect of collisions is considered by analyzing the local dynamics between contending WLANs at every state of the CTMC. Simulation results confirm the accuracy of the presented approach.
