— As the use of sensor networks increases, security in this domain becomes a very real concern. One fundamental aspect of providing confidentiality and authentication is key dis...
—We present 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 en...
We propose a framework for error robust real-time video transmission over wireless networks. In our approach, we cope with packet loss on the downlink by retransmitting lost packe...
We combine multiple description (MD) quantization, entropy coding, and data partitioning to improve the error resiliency of images over varying packet loss channels. Our proposed ...
— Overlay-based multicast has been proposed as a key alternative for large-scale group communication. There is ample motivation for such an approach, as it delivers the scalabili...
