Abstract
Improved distribution of video information in an infrastructure-based wireless network is provided. A wireless channel condition between the video server node and each of the plurality of receiver nodes is determined. Receiver nodes are assigned into one of a first group and a second group using the measured wireless channel conditions, wherein receiver nodes assigned to the first group have, on average, a better measured wireless channel condition than that of receiver nodes assigned to the second group. At least some of the receiver nodes of the first group of nodes are selected to serve as relay nodes. Video information is then transmitted wirelessly from the video server node to the receiver nodes assigned to the first group. Each of the selected relay nodes then transmits at least a part of the video information to the receiver nodes of the second group.
