Aircrafts in commercial routes have been proposed in some previous work as a novel DTN bundle carriers. Satellites can be one of the hops in this application. DTN suffers from intermittent disconnections, long delays and has scarce resources. It is a challenge to control the admission to these resources to provide better QoS and ensure optimum resource utilisation. Furthermore, providing fairness...
We propose and analyze two strategies to provide different levels of quality of service (QoS) to the DVB-SH standard. An extension of the interleaving scheme is investigated to support low latency service requirements for interactive services based on short messages. The first approach is a straightforward extension of the DVB-SH interleaver scheme based on an early-uniform interleaver profile, and...
Sirius XM Radio, through its Sirius and XM Satellite Radio systems, broadcasts continuous high quality audio, video and data content to over nineteen million subscribers throughout the Continental United States (CONUS) and Canada. The original Sirius system utilizes three satellites in highly inclined orbits. The original XM system utilizes two satellites in geostationary orbits. Both systems achieve...
Designing new satellite access protocols or validating innovative satellite network concepts, evaluating their performances and demonstrating them require powerful test tools to check their compliance with satellite system requirements. Obviously, such tools have to be as representative as possible of typical satellite telecom systems, but also adaptable to specific research and engineering needs...
Delay-/Disruption-Tolerant Networking represents an innovative way to cope with satellite communications impairments. In this view, the paper presents an in-depth analysis of implications of a DTN approach to satellite communications, focusing on these fundamental aspects: network architecture, security, and Quality of Service (QoS). For each topic, commonalities and differences between DTN and Performance...
The convergence of satellite DVB-S2/RCS broadcasting/multicasting systems side by side with terrestrial mobile satellite and broadband wireless 4G WiMAX becomes the most perspective networking technology for BRIC and other countries with many remote, rural, and difficult for access (RRD) territories. The RRD regions differ also by the poor terrestrial core infrastructures and sparsely populated areas...
