Abstract

This paper discusses the maximization of user-perceived quality of layered media in wireless networks. We present a system model and an optimization framework for such networks assuming: (i) the data rates are nested, (ii) the media is multicast, (iii) layered and (iv) the media layer information is available in lower network layers based on cross-layer information. In order to show the general applicability of the proposal, different maximization targets and algorithmic solutions are presented.
