In this paper, a novel algorithm is presented, suitable for deriving effective service scheduling schemes under the Hybrid Controlled Channel Access (HCCA) method employed as the centralized polling mechanism for parameterized channel access in the IEEE802.11e specification. Compared to existing service schedulers, the proposed novel algorithm demonstrates a significant bandwidth management improvement and optimal QoS performance, especially for high-quality audio/video streaming applications. The IEEE 802.11 Wireless Local Area Networks (WLANs) standard represents a rapidly emerging technology for a wide range of applications, such as broadband wireless access and digital media distribution within home environments.
