ABSTRACT
This chapter introduces network-adaptive streaming that aims to improve the quality of video playout at the mobile nodes while utilizing given limited resources in the WiFi wireless network. The WiFi Alliance is also trying to make the WiFi hotspot program that provides seamless WiFi connections to mobile devices in urban areas. The error control–based adaptation addresses the reliable video transmission over the fading WiFi channels, which relies heavily on the coordinated protection effort in response to time-varying channel and source variations. Wireless video streaming over the WiFi network is inherently vulnerable to burst packet losses caused by dynamic wireless channel variations with time-varying fading and interference. The network-adaptive selective error control improves the video playout quality by selectively protecting against the packet losses of error-prone WiFi wireless network. In real practice, the aforementioned network adaptation for wireless channel is facing severe difficulty in the monitoring aspect.
