Resource allocation algorithm driven by QoS-QoE for VLC/RF heterogeneous networks
To efficiently ensure the quality of service(QoS) and quality of experience(QoE) of visible light communication/radio frequency (VLC/RF) heterogeneous networks, a QoS-QoE driven resource allocation algorithm for VLC/RF heterogeneous networks is proposed. First, the success access probability of users is analyzed based on their locations and the blocking situation of VLC links, and a switching service model is established to solve the effective capacity of the service process. The interruption uniform process (IUP) is used to describe the arrival of traffic, and the effective bandwidth of the IUP arrival is calculated. Then, the RF service rate that satisfies the delay QoS requirement is derived, and the QoE evaluation system is established based on the mapping relationship between QoS and QoE. Finally, the influence of different parameters on the resource allocation algorithm is analyzed through simulation. The simulation results show that the algorithm can ensure QoS and QoE at the same time.
