The 802.16e standard for broadband wireless access mandates the presence of QoS classes, but does not specify guidelines for the scheduler implementation or mechanisms to ensure air time fairness. The authors' study demonstrates the feasibility of controlling downlink airtime fairness for slices while running above a proprietary WiMAX BaseStation (BS) scheduler. They design and implement a virtualized infrastructure that allows users to obtain at least an allocated percentage of BS resources in the presence of saturation and link degradation.
