Abstract: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… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
