The appearance of several IEEE 802.11 variants made possible the availability of many wireless local area network access options for end users in the same location. Network requirements for IPTV service become higher when the quality of the delivered video is higher. Moreover, in wireless networks the network performance is highly degraded when there is high number of users. In this paper, the authors propose a protocol and algorithm that makes to handover IPTV users to the best available WLAN when the QoS parameters received by the end user reaches a threshold. It guarantees anytime the highest QoS for the user.
