The International Civil Aviation Organization (ICAO) has defined a mobile IPv6-based Aeronautical Telecommunications Network (ATN/IPS) as a next generation communication network for future Air Traffic Management (ATM). The ATN/IPS will be used with different terrestrial and satellite link technologies for supporting future ATM. In parallel, non-operational(More)
It is widely recognized that emergency management and disaster recovery systems are an issue of paramount importance in communities through the world. The definition of a public safety communications infrastructure is a high-priority task due to the lack of interoperability between emergency response departments, the reduced mobility during coordinated(More)
Within the next 10-15 years, air-traffic management (ATM) will be primarily based on data communications and voice communication will be mostly used as fallback solution. Furthermore, it is foreseen that IP-based networking solutions for A/G communication will be deployed for cost savings, high reliability and an optimal alignment with the evolution of(More)
Digital video broadcast return channel via satellite system (RCS) is a key European standard that specifies a broadband satellite system using dynamic capacity assignment and multi-frequency time-division multiple access. This study introduces new architectural components for an RCS system to support advanced Internet protocol (IP)-oriented multimedia. This(More)
OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract—The Low Extra Delay Background Transport (LED-BAT) protocol is a recently standardized protocol that aims to offer a scavenger service (i.e. the goal is to exploit the remaining and unused capacity of a link).(More)
A DTN routing scheme for quasi-deterministic networks with application to LEO satellites topology. OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. Abstract—We propose a novel DTN routing algorithm, called DQN, specifically designed for quasi-deterministic networks(More)
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(More)
Emergency Management is an important topic for research community worldwide, especially after recent major disasters. The problem of supporting mobility at the disaster site to rescue teams equipped with different heterogeneous access technologies and providing interoperability between different agencies and jurisdictions is still under investigation. In(More)
Emulation is a cost effective and efficient tool to perform performances evaluation and innovative access and network techniques validation. Its ability to interconnect real equipments with real applications provides excellent demonstrations means. The main problem is to overcome the emulation weakness which is the accuracy of the model reproducing the(More)
