Energy Efficient Fair Content Distribution over LTE Networks using Bluetooth Piconets

Abstract

Energy efficient content distribution with mobileto-mobile cooperation is considered. The distribution method is based on long range transmission from a base station and on short range cooperation between mobile terminals. Long range communication is assumed over an LTE network whereas Bluetooth is considered on the short range. A low complexity energy-efficient content distribution approach is presented and compared to the optimal solution. Results show that the proposed approach leads to more fairness than the optimal solution, at the expense of a slight performance degradation in terms of energy savings. However, significant energy savings are obtained compared to the scenario without mobile-to-mobile cooperation. Thus, the use of Bluetooth in cooperative short range communications can lead to increased energy efficiency for mobile terminals.
