A CoMP based LTE-A simulator for green communications

Abstract

In order to assess the performance of new energy efficient network technologies for green communication, network power consumption and system level simulations are crucial in LTE-Advanced (LTE-A). In this paper, we present a MATLAB based simulator to measure the network performance in terms of throughput, energy efficiency (EE), and on-grid energy savings etc. considering tempo-spatial dynamics of traffic demand. The simulator is built on renewable energy powered cellular network and is capable of evaluating the downlink performances under different coordinated multipoint (CoMP) schemes such as dynamic point selection (DPS) and joint transmission (JT). In JT transmission technique, the number of base stations (BSs) is not limited to two but can be extended to multiple numbers of BSs to serve a single user equipment (UE) for attaining a better quality of services (QoS). The proposed cellular network deploys individual energy storage device, renewable energy source, and resistive power lines among BSs for energy cooperation. The aim of this simulator is optimizing the green energy utilization and thereby reducing the on-grid power consumption. The simulator is offered for free under an academic, non-commercial use license, a first to the authors knowledge.
