As mobile devices, such as smart phones and tablet PCs, become more and more ubiquitous, it is increasingly popular for users to watch online video streaming on their mobile devices. Because of the nature of wireless broadcast, a wireless router (e.g., an access point or cellular tower) can retrieve video streams from the video server and then efficiently multicast them via wireless medium to multiple clients who are interested in those videos.
