Abstract:
The quick evolution in technologies has allowed IPTV video stream delivery over IP networks. For that reason consumers have anticipated predictions in which the evolution of IP-based next-generation networks may be eventually driven by video service delivery requirements. An IEEE 802.16j mobile WiMAX relay network is a next-generation mobile wireless broadband network. Compared to IEEE 802.16e which also supports mobility, IEEE 802.16j introduces relay stations to the network to offer improved coverage and capacity over multihop radio systems. However, to supply different IPTV services (HD-TV, SD-TV, Web-TV and Mobile-TV) to consumers, providers must have a video server for each IPTV service type, which increases network resource consumption. In this paper, we present a new mechanism for Multicast Broadcast Service (MBS). In particular, the proposed solution allows a provider to offer different IPTV services to varied users requests via WiMAX multihop relay access network. Results show that the proposed scheme ensures network load optimization and reduces bandwidth consumption.
