The resource allocation problem to support scalable-video multicast for wireless relay networks is complex due to the existence of the relay station. In this paper, the authors consider the resource allocation for SVC multicast over two-hop wireless relay networks to maximize the total system utility of all users where the system utility can be a general non-negative, non-decreasing function. They model the problem in three-layer structure (choice elements, action elements, and user elements) to cope with the joint dependency and overlapping phenomena.
