Effective Bandwidth Control Policies for QoS- enabled Wireless Networks

Abstract- In this paper, an admission control policy is introduced, suitable for efficiently controlling traffic admissions under the Enhanced Distributed Channel Access (EDCA) method, which is employed as the basic access scheme in the latest IEEE802.11e draft specification. Moreover, based on a novel traffic renegotiation strategy, an adaptive bandwidth allocation scheme is presented, which monitors the admitted traffic bandwidth resources and provides constant QoS guarantees under unpredictable wireless environment conditions, such as channel degradation and data bursting
