Power consumption model using green policies in Heterogeneous Networks

Abstract

Although the LTE systems provides high data-rate, low latency and spectrum flexibility, the coverage holes due to the cell edge and high interference areas are still an open issue. The Heterogeneous Networks (HetNets) can be a possible solution to this problems. The HetNet paradigms overlaps low power base stations (BSs) with different transmitted powers within a macro cellular coverage. However, the dense deployment of BSs increases the power consumption of the network and, as a consequence, decreases the system performance due to the high inter-cell interference. In this paper, we propose a power control scheme based on green policies in order to enhance the power saving over Heterogeneous Networks (HetNets) in Long Term Evolution (LTE) systems. In particular, the aim of the proposed framework is to increase the energy efficiency of the system, without decreasing the network throughput. An extensive simulation campaign has been conducted through the usage of the Network Simulator 3 (NS-3). The obtained results show that the proposed green power control reduces the power consumption and enhances the energy efficiency of the system without decreases the throughput of both the BSs and users (UEs).

Small‐cell planning in LTE HetNet to improve energy efficiency

“…In particular, the energy efficiency is defined by the ratio of the HetNet's throughput to the amount of energy consumed by the whole BSs (including the newly deployed ones). 14,15 To solve the problem, our idea is to first identify those user devices whose traffic demands cannot be satisfied by the original (macrocell) BSs. Afterwards, we develop different clustering strategies to find out the suitable locations to place microcell and picocell BSs and check whether they have sufficient resource to serve their user devices.…”

Energy and spectrum efficiency trade-off for Green Small Cell Networks

“…A joint BS association and power control scheme which intent to satisfy the user's target signal-to-interference-plus-noise ratio (SINR) for the uplink of a large-scale HetNets is proposed in [7]. An efficient power allocation scheme to investigate the power consumption and EE without degrading the network throughput in Long Term Evolution (LTE) HetNets is proposed in [8]. In [9], a distributed non-cooperative game is proposed to improve the system EE in the downlink transmission of HetNets.…”
