Energy aware handover in LBS interference for 5G Dense Heterogeneous Network

The key performance metrics for the Next generation wireless communication system is the Energy efficiency. We use dense Heterogenous Networks(HetNets) which comprises of Macro cell and Small cell where small cells include femto cell, pico cell, and micro cells. The femto cells are deployed in the macrocell area to improve the indoor coverage and provide better user experience. The mass deployment of femtocell faces a number of challenges among which interference management is very important. In this paper we consider the energy aware handovers between macro and femto base stations where the user equipment changes its services from one base station to another since the target one will offer better quality of performance. Handover decision can either be mobile initiated or network initiated and this decision is truly based on the received signal strength (RSS). The experiment is carried out using Network Simulator NS-3 and the results show that the proposed solution exhibits better performance in terms of quality of service metrics
