Optimized Energy-Aware Multicasting Over Wireless Cellular Networks With Multihop Cooperation

Multicasting provides a scalable solution to deliver a common content to a set of requesting mobile terminals in wireless broadband networks. However, the multicasting rate is limited by the worst channel conditions of the mobile terminals which increases the content download time, and consequently, increases the energy consumed from the mobile terminals' batteries. In this paper, the authors address the problem of cooperative multicasting where a base station multicasts the content over a cellular network to an optimally selected set of mobile terminals, that in turn multicast the content over multihop connections to other mobile terminals in their vicinity which leads to the formation of cooperative groups.
