Robust transmission of video is a dominant requirement of future applications over wireless networks. MPEG4 is an object based video encoding technique which is suitable for wireless applications due to its high compression performance, scalable video coding techniques, error-resilient capability and object-based coding functionalities. In this paper, we first model traces of MPEG4 traffic. Based on these models, we develop tools for MPEG4 traffic generation. These tools have an adaptive rate control function that is capable of simulating MPEG4's scalable video coding. These tools can be used as source traffic generator in network simulators. This enables the study of MPEG4 transmission performance over wireless networks by using simulation. We model and generate the traffic based on the Transform Expand Sample (TES) methodology. In our experiment, we generate MPEG4 traffic and show the performance in terms of good matching of the characteristics of the modeled traffic.
