Bandwidth Allocation for Multimedia VBR Traffic
Multimedia applications are becoming more and more popular. Recently, there has been increased interest in transmitting multimedia files with VBR (Variable Bit Rate) without jitter in order to provide a high QoS. Research at the LIST lab has enabled development of a scheme which uses the transmitter buffer size to allocate the efficient TDMA slot time. It maintains the average transmitter buffer size and average allocated TDMA bandwidth. According to these values, it can increase or decrease the bandwidth allocation to adapt the optimal bandwidth allocation for every time interval. Extensive simulation results show that our reservation scheme outperforms the best previously known schemes.
Traffic Synthesis

This paper focuses on MPEG coded video traffic models, which can capture the statistical properties of MPEG video data. The basic ideas behind these models are to decompose an MPEG compressed video sequence into three parts according to the frame types (I, P, and B frame). Each type is described by a gamma distribution. MPEG traffic modeling is accomplished by combining the I, P, and B frames. The MPEG traffic model presented in this paper is used to model MPEG traffic for network simulation.
