Minimizing Battery Consumption in Mobile Device To Device and Spectrum Sharing Network: An Approach

Power optimization in Device to Device networks has been studied using different approaches in literature which include allocation of resources (bandwidth and power) as well as Interference mitigation. However, in this paper, we propose a first exact modelling of several network parameters and their interaction in order to minimize the energy consumption in a Device to Device and Spectrum Sharing network. An optimization algorithm to also satisfy users with adequate quality of service while minimizing the Transmit power and achieving overall system Energy Efficiency is being proposed. With the proposed algorithm in this work, power level requirement for communication would be minimized without compromising the quality of service, therefore making the entire system energy efficient which is a metric for green communication.
