Abstract

In order to fairly access a shared wireless channel and allocate network resources, resource management mechanisms are required for controlling link-sharing in wireless local area networks (WLANs), which are expected to support real-time and multimedia applications. We then propose an extended Class-Based Queueing (CBQ) service in this paper based on controlled hierarchical link-sharing model with QoS-aware MAC protocol of IEEE 802.11e to support sharing of the link bandwidth among different users in a distributed manner. Dynamically adjusting parameters in IEEE 802.11e, e.g., AIFS, CW min, and CWmax, which are used to control the probability to access the channel, our scheme is able to achieve fair channel sharing. Using a simulation approach, we demonstrate the fairness improvement of our scheme is good.
