摘要

A rate-variance-envelop-based admission control (RVAC) has previously been proposed for IEEE 802.11e wireless networks. By leveraging the multiplexing gain of variable bit rate traffic, RVAC enjoys high network utilization. However, it may suffer from capacity loss due to large polling overheads, and its conservative approach to ensure the quality of service. To overcome these issues, we propose a per-flow polling scheme and derive the capacity by utilizing a stochastic ON–OFF model together with a D/G/1 model. The advantages of our method over RVAC are demonstrated through both analytical and simulation results in respect to the system capacity.
