Application of Throughput Drop Estimation Model under Partially Overlapping Channels to Channel Assignment in IEEE 802.11n WLAN

Abstract

Currently, the IEEE 802.11n wireless local-area network (WLAN) has been extensively deployed world-wide. For the efficient chan nel assignment to access-points (APs) from the limited number of par tially overlapping channels (POCs) at 2.4GHz band, we have studied the throughput drop estimation model under POCs for concurrently commu nicating links. However, the effectiveness of the model in the channel as signment in WLAN has not been examined. In this paper, we study the application of the model to the channel assignment of the APs in 802.11n WLAN. Through simulations and experiments in various topologies, we verify the effectiveness of the proposal.
