Presenting an advanced simulation tool-set for video transmission performance evaluation is the objective of this paper. This tool-set integrates NS-2 with Evalvid plus a new coding mechanism: Multiple Description Coding (MDC). Using the integrated NS-2 simulator, researchers can easily evaluate specific transmission performance of a variety of videos varying in codec or coding mechanisms. Researchers can analyze their own design, such as their own improved network protocols or QoS control schemes, in a realistic simulation environment without delving into the simulator itself. Besides, by using the tool-set, researchers can acquire video transmission quality not only with former evaluation metrics, but also with real recombined video, which can be played out and observed. In conclusion, researchers who utilize our evolved simulation tool-set will benefit from speedily verifying their video transmission over wireless network designs.
