Abstract
Video services are expected to account for a large portion of the
traffic in future wireless networks. Therefore, realistic traffic
sources are needed to investigate the network performance of future
communication protocols. Previously, we provided a publicly available
library of frame size traces of long MPEG-4 and H.263 encoded videos
in the QCIF format resulting in low bandwidth video streams. These
traces can be used in 3G network simulations. Some future communication
systems, such as WLAN systems, offer high data rates and therefore
high quality video can be transmitted over such higher speed networks.
We now present an addition to our existing trace library. For this
addition we collected over 100 pre-encoded video sequences from the
Web, generated the trace files, and conducted a thorough statistical
evaluation. Because the pre-encoded video sequences are encoded by
different users, their video settings differ in terms of codec, quality,
format, and length. The advantage of user diversity for encoding
is that it reflects very well the traffic situation in upcoming WLANs.
Thus, the new traces are very suitable for the network performance
evaluation of future WLANs.
