Fair QoS multi-resource allocation for wireless LAN

摘要

We consider the problem of allocating two network resources (wireless bandwidth and backhaul router buffer) to support fair QoS in WLAN. We transform the QoS requirements to multi-resource demands and apply the DRF scheme to achieve fair allocation of the two different types of resources. We define a QoS utility function which measures the user QoS satisfaction. We briefly prove the property of resource-based strategy proofness of DRF, the corresponding mathematical expression is used to prove QoS-based strategy-proofness in terms of both resource share and user QoS. Finally our simulation results confirm the properties of DRF and demonstrate that our DRF-based approach performs better than several multi-resource allocation schemes with respect to both fairness and utility.
