Self organized energy efficient position aided relays in LTEA

Abstract Energy is an expensive commodity in Long term Evolution-Advanced networks (LTEA). In recent years many researchers have proposed different approaches to minimize energy consumption in LTEA. Relays and the Self Organized Network (SON) technologies are an attractive solution to cost reduction, and to minimize energy utilization in LTEA. SON has the potential for self-configuring, self-optimizing, self-healing and minimizing the energy consumption in the network and by deploying Relay Nodes (RNs) it enhances the capacity, the diversity and fairness in the network. In this paper we consider the self-optimizing and self-healing properties of SON and propose a novel energy efficient SON based position aided relay algorithm. The proposed algorithm is capable of reducing the energy consumption by 50% in the best case scenario. A System Level Simulator (SLS) is used to evaluate the performance of the proposed algorithm through numerical results.
