Title
An on-line measurement-based admission control for VBR video traffic in wireless multimedia home networks
Abstract
Variable bit rate (VBR) video traffic with high data rate is expected to be the largest proportion of traffic carried by future wireless home networks. In order to guarantee quality-of-service (QoS) requirements of such type of VBR video traffic and improve channel utilization, this paper proposes an on-line measurement-based admission control scheme. The proposed scheme is designed based on the property of the aggregate VBR video traffic is lognormal distributed and consists of two main components which are measurement process and admission decision respectively. The measurement process applies a linear Kalman filter to estimate statistical parameters of aggregate VBR video traffic. Then, the estimated statistical parameters are used to calculate the effective bandwidth for admission decision. The proposed scheme is computational efficiently and accurate without much prior information of traffic. Simulation results confirm its accuracy and also show that the proposed scheme performs well for small number of connections as well as large number of connections.
