Network support for mobile multimedia using a self-adaptive distributed proxy

Recent advancements in video and audio codec technologies (e.g., RealVideo [18]) make multimedia streaming possible across a wide range of network conditions. With an increasing trend of ubiquitous connectivity, more and more areas have overlapping coverage of multiple wired and wireless networks. Because the best network service changes as the user moves, to provide good multimedia application performance, the service needs to adapt to user movement as well as network and computational resource variations. For wireless multimedia applications, one must ensure smooth transitions when network connectivity changes. We argue that network adaptations for multimedia applications should be provided at the application layer with help from proxies in the network. The reasons are ease of programming, ease of deployment, better faulttolerance, and greater scalability. We propose a self-adaptive distributed proxy system that provides streaming multimedia service to mobile wireless clients. Our s...
