Abstract

Wireless local area networks are a viable technology to support multimedia traffic. One of the prominent wireless local area network standards is the IEEE 802.11 standard. In wireless multimedia networks, mobile stations will be capable of generating a heterogeneous traffic mix with varying bandwidth requirements. In this paper, we investigate in detail, a distributed fair queueing scheduler for 802.11 wireless network to schedule both uplink and downlink traffic flows. This scheme is a combination of the distributed deficit round robin scheme together with its centralized counterpart. The performance of the proposed scheduler is evaluated by computer simulation, showing that the fair queueing scheduler outperforms the scheduler based on round robin service discipline from a capacity viewpoint.
