Optimal User Selection using BWM Tool

The technology has known a great development in the last years, which leads to the apparition of several devices. This diversity permits users to connect freely to the network. However, the mobile system’s energy consumption is maximized. Therefore, reducing the energy consumption of the mobile user is a key issue for Heterogeneous Networks(HetNet). The main aim of this paper is the minimization of energy consumption by the use of a wise user association strategy. The novel approach consists of associating the users taking into account their optimal cost of association to the available network.This selection is realized by the Best Worst Method(BWM). Simulation results prove that the proposed approach has significantly improved network performances
