In this paper,wepresent a scheduling algorithm that enhances the performance of the standard IEEE802.11e scheduler for the HybridCoordination FunctionControlledChannelAccessmode. Themain contribution in designing the proposed scheduler is the ability to accommodate multiple streams with different levels of Quality of Service requirements concurrently(More)
The IEEE S02.lle standard defines a reference scheduler that allocates transmission opportunities (TXOP) to traffic streams based on mean data rate and minimum physical rate. However, the reference scheduler is only efficient for streams with strict constant bit rate (CBR) characteristics. This paper presents a scheduling scheme named as the Selectivity(More)
