Overall Performance Assessment of Energy-Aware Cooperative Techniques Exploiting Multiple Description and Scalable Video Coding Schemes

In this paper, the authors develop and analyze energy-efficient cooperative techniques for multimedia applications over wireless networks. The composite cellular-short-range network architecture is explored by using multiple description coding and scalable video coding schemes. In order to provide an overall and fair assessment of the schemes, different approaches are evaluated and discussed. The techniques are compared not only in terms of their energy gain with respect to non-cooperative (autonomous) operation but also considering the quality of the delivered video signal.
