Cross-Layer Resource Allocation Based on Interference Management and QoS-Driven for VLC-WiFi Network
Visible Light Communication(VLC)and Wireless Fidelity(WiFi)network are considered one of the key technologies for future 6G mobile communication.So a Cross-layer Resource Allocation Mecha-nism based on Interference Management and QoS-driven(CRAMIMQ)is proposed to improve the proba-bility that allocating resource can meet service's quality of service(QoS)requirement.According to the channel state of the physical layer and the queue state of the media access control layer in VLC-WiFi net-work,an adaptive QoS level evaluation of VLC-WiFi transmission downlink and channel's quality control method are designed in proposed CRAMIMQ.Then a cross layer resource allocation method based on in-terference management and QoS driven is put forward to meet the QoS requirements of service.Compared to the QoS-aware cross-layer dynamic resource allocation(QoS CLDRA)method,The simulation results show that proposed CRAMIMQ can improve the successful probability of service access,and achieve a maximum system throughput increase of 5.64％and a 21.8％reduction in VLC buffer queue length ap-proximately.
