Resumen

The mobility and ubiquity for any type of device to access the IPTV network must be supplied by the service provider. The minimum bandwidth required in the access network to provide IPTV services jointly with the necessity to guarantee the Quality of Experience (QoE) to the user makes the need of algorithms to combine different wireless standards and technologies in the access network. In this paper, we propose a system that decides which type of wireless access network to connect with (for dual-band and tri-band devices) depending on the requirements of the IPTV client, the available networks, and some network parameters, such as the number of loss packets and packet delay, to provide the maximum QoE to the customer. The measurements taken in a real environment from the wireless networks allow us to know the weight of the parameters in the proposed algorithm.
