Abstract

IEEE 802.11e standard develops a reference design for a sample scheduler and admission control unit to support the contention-free access. However, the reference design can not effectively utilize the bandwidth. This paper proposes an equal-spacing-based (equal-SP) design to address the problem. In the equal-SP design, which generalizes the reference design, each stream is scheduled with equal-spacing and different streams are scheduled with different equal-spacings. The equal-SP design not only keeps all advantages of the reference design, but it can also utilize the bandwidth effectively.
