A Signaling Architecture for Multimedia MBS Over WiMAX
In this paper, the authors design and demonstrate a signaling architecture for multicast and broadcast services over a laboratory emulated Worldwide interoperability for Microwave Access (WiMAX) network. WiMAX is a broadband wireless access technology which includes different quality of service levels. Currently, a significant research effort focuses on data transmission optimization and mobility support for multicast and broadcast services. Their proposal is fully IP-based, and the relevant signaling architecture is modular in all its entities and extensible to other, non-WiMAX, IP access networks. They specifically address the non-trivial support of multicast services, which has been demonstrated through a prototype implementation of their proposal for an Internet Protocol TeleVision (IPTV) service.
