An association management scheme for seamless IPTV services in a WLAN

Abstract

In this paper, a novel association management scheme is proposed to support quality requirement of IPTV services in a wireless LAN without modifying the IEEE 802.11 standard. A user terminal keeps monitoring a contention level of access points (APs) around it and a quality of an ongoing IPTV service. If the quality deteriorates below a threshold, the terminal reassociates with another AP having the least load so that the ongoing IPTV program is played without disruption.
