Quality-of-experience-oriented network selection for indoor VLC heterogeneous networks

In this paper, we propose a novel network selection method oriented to users’ quality-of-experience (QoE) for indoor visible light communication (VLC) heterogeneous networks. The proposed method considers the difference between user requirements for different parameters and the actual performance of each candidate network in these reference indicators. To improve QoE, a new indicator named “benefit-cost-ratio (BCR)” is defined to represent the user demand under different businesses and assist in sorting alternatives to select the optimal network for access. Simulation results show that through the proposed network selection scheme, the candidate networks could be effectively ranked and adjusted according to user requirements.
