Title
Latency-Aware Fair Scheduling for Spatial Reuse in WLANs: A Lyapunov Optimization Approach
Abstract
The IEEE 802.11ax has introduced the concurrent transmissions among neighboring wireless local area networks (WLANs) to facilitate spatial reuse. As a side effect, the scheduling problem has become more challenging due to the appearance of unmanaged co-channel interference. This paper proposes a latency-aware fair resource scheduling scheme in dense WLANs with Lyapunov optimization. In the scheduling scheme, we formulate a scheduling problem for WLANs with the stabilization of the transmission queue, which is one of the quality of service (QoS) issues and the fairness of the instantaneous data rate as a stochastic optimization problem. This problem is solved by using Lyapunov optimization, which eliminates the time average constraints of the problem. We performed numerical simulations in dense WLANs, and the results confirm that the proposed scheme guarantees an allowable queue size. the results also show that the proposed scheme achieves a higher fairness index and a smaller queue size than compared methods.
