An Energy Efficient Proposal in Shared Relay-Based LTE Network

Energy is an expensive commodity in Long term Evolution-Advanced (LTEA) networks. In the recent years many researchers have proposed different approaches to minimize energy consumption in LTEA according to mobile users' point of view. In this paper we analyze the energy consumption of the network according to the operators' point of views. Network sharing and the Self Organized Network (SON) technologies are attractive solutions for cost reduction, and minimizing energy utilization in LTEA. The purpose of this paper is to provide a novel framework for minimizing energy cost per bit and assist with Self Organized Load Balancing algorithm (SO-LB) in shared network. Simulation results show that, by employing SOLB in a shared network, it is possible to save 15-20% of the energy normally consumed in the LTEA non shared networks
