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...
The energy consumption of wireless access networks is rapidly increasing and in some countries it amounts for more than 55% of the whole communication sector and for a non negligible part of the operational costs of mobile operators. The new wireless technologies with a growth of data rates by a factor of roughly 10 every 5years and the increase in the number of users result in a doubling of the power...
