Allocation of wireless spectrum and transmission power for video multicast in a two-tier femtocell network is a challenging problem because of network dynamics, variable video bit-rates, and heterogeneous clients who watch various videos as well as are at different locations. Since femtocells provide coverage using typical cellular system air interface, the co-channel interference may significantly...
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...
During recent years, the success of live swarm-based P2P streaming system has been witnessed. Nevertheless, how to design an effective mechanism for mitigating video quality degradation in a lossy network environment is still not thoroughly resolved yet. Unlike conventional client-server paradigm, there is data availability problem in swarm-based P2P streaming system. If we directly conduct the importance-first...
