This paper presents MobiStream - a video streaming system that exploits the perceptual value in video content and the characteristics of the link layer and physical layer channels to enable error-resilient video streaming over Wireless Wide-Area Networks (WWANs). The key building block in MobiStream is the use of link-layer based, but application-controlled, Virtual Channels (ViCs) abstraction. Each virtual channel offers a level of reliability and statistical loss gaurantees using 'Awareness' of the characteristics of link-layer and physical layer channels.
