The combination of video streaming services and wireless networks plays an important role in many fields. In this paper, we present an NS-3-based simulation platform for evaluating and optimizing the performance of the video streaming application over wireless networks. The simulation is designed to provide real-time measurements, and thus it saves the high costs for real equipment. The developed platform consists of the video streaming server, video streaming client, and wireless network environment, where the video streaming operation is implemented under UDP protocol and is equipped with an application-level adaptive rate controller. We use the platform to simulate different use cases of sharing a wireless multi-access channel among multiple video streams.
