Abstract
802.16j is one of the most popular extensions among IEEE 802.16 family. It aims to lower deployment cost and to enhance network coverage by using wireless relay stations. On the other hand, Wireless multicast for IPTV is also getting more and more popular. In this thesis, we discuss how to allocate resources to different layer-encoded TV programs using multicast services, especially in multi-hop relay networks. We first provide a brief introduction to IEEE 802.16 and 802.16j MAC. Then we prove that our problem is NP-hard and propose a heuristic algorithm called U-LEM-M to solve this problem efficiently. We show our algorithm outperforms other algorithms via simulation.
