Wireless video multicast enables delivery of popular events to many wireless users in a bandwidth efficient manner. However, providing good and stable video quality to a large number of users with varying channel conditions remains elusive. The authors propose to integrate layered video coding with cooperative communication to enable efficient and robust video multicast in infrastructure-based wireless networks. They determine the user partition and transmission time scheduling that can optimize a multicast performance criterion. In recent years, the demand for video applications over wireless networks rose with the increase in both the bandwidth of wireless channels and the computational power of mobile devices.
