Stretchable Architectures for Next Generation Cellular Networks
نویسنده
چکیده
This paper examines the technique of conserving energy in 3G cellular systems by allowing calls between a mobile and the base station to be forwarded by some other mobile in the cell. This stretched call has the benefit of reducing overall energy cost for the call in cases where the calling mobile is NLOS (Non Line of Sight) to the base station but is LOS to the intermediary and the intermediary is LOS to the base station. The main contributions of the paper are twofold: first, we show how this stretched call model can be implemented in UMTS and CDMA2000; second, we show that this stretched call model results in overall energy savings in a cell of between 2x and 7x.
