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...
In this paper, an overview of recent achievements in the design and decoding of non-binary low-density parity-check (LDPC) codes is provided. Non-binary constructions based on ultra-sparse matrices are compared with binary low-density parity-check codes and turbo codes from satellite communication standards, to show that larger coding gains (outperforming the binary competitors by at least 0.3 dB)...
This paper aims at forecasting the role of Satellite Communications (SatCom) in the context of Future Internet and particularly of the future Internet-enabled smart infrastructures in support of some European Societal Grand Challenges. It also aims at identifying the necessary technological enablers which need to be developed by the European SatCom industry for the emerging SatCom solutions.
On-Board Processing (OBP) technology has been already in the satellite scene for almost two decades. It has been a difficult path and for a long time considered an added but expensive value brought to the satellite payload. Today, it is a commercial and competitive reality. In the case of Thales Alenia Space (TAS), a new generation of OBP solutions are available to satisfy the always more demanding...
This paper presents the work that is currently performed in the E-SPONDER (FP7-242411) project. E-SPONDER is a project co-funded by the European Commission under its Security Program. E-SPONDER is a suite of real-time data-centric technologies that will provide information and communication support to first responders which act during normal and abnormal events (crises). It will investigate the use...
