Abstract

With the explosive growth of the Internet and dramatic increase in wireless access, users expect high quality streaming media service over wireless network. Due to the high bandwidth requirements and the long-lived nature of streaming objects, it is a challenge to provide efficient multimedia streaming service in highly dynamic wireless environment. This paper discusses the ways to improve wireless network streaming media service quality using proxy caching. We present a novel streaming media caching model for cell-based wireless networks. Its architecture is compatible and interoperable with existing wireless network infrastructure. The model utilizes some well known caching techniques such as segmentation, prefix caching, and cooperative caching. We also describe the implementation details and explain how this model works. Our evaluations show that this model is effective in the high quality streaming service for wireless networks. The model not only reduces the initial delay of applications, but also minimizes the application startup delay and wireless network bandwidth utilization.
