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.
