Maximizing service availability for secure satellite broadcasting

Cryptography is the most suitable technique to protect the access to subscribed value-added services for mobile applications provided through satellite broadcasting (e.g. localization and mobile TV). However, if a temporary loss of signal is experienced by receivers, not only the data streaming is compromised, but also the key management-related messages. Hence, when the signal is received agai...

Pyramid Broadcasting for Video on Demand Service

The proposed scheme of pyramid broadcasting is a new way of rendering Video On Demand service at metropolitan scale. In pyramid broadcasting, the most frequently requested movies are multiplexed on the broadcast network, resulting in radical improvement of access time and e cient bandwidth utilization. We provide analytical and experimental evaluations of pyramid broadcasting based on its imple...

High Performance Data Broadcasting Systems

Data broadcasting as a means of efficient data dissemination is a key technology facilitating ubiquitous computing. For this reason, broadcast scheduling algorithms have received a lot of attention. However, all existing algorithms make the core assumption that the data items to be broadcast are immediately available in the transmitter’s queue, ignoring the key role that the disk subsystem and ...
