QoS-Driven Load Balancing in Hybrid LiFi and WiFi Networks

This work studies the quality of service (QoS) performance wireless networks that integrate light fidelity (LiFi) and (WiFi). While hybrid network is potential for improving capacity, load balancing becomes essential challenging due to nature heterogeneous access points (APs). A number have been conducted address this issue, focusing on maximising capacity with user fairness constraints. However, in practice, QoS metrics including packet loss ratio latency are important services. In paper, QoS-driven studied LiFi WiFi (HLWNets) two scenarios: single-AP association (SA) multi-AP (MA). each case, an optimisation problem formulated minimise latency, a low-complexity iterative algorithm proposed solve problem. Results show novel methods, especially MA, can effectively balance traffic loads among APs improve performance. addition, more subflows better MA provides. Targeting same level QoS, achieve system throughput up 160% higher than signal strength strategy 130% proportional balancing.
