Network Centric Systems


Due to the massive introduction of networking digital systems and devices, information capabilities are constantly expanding. However, requirement capture, quality and guarantee of services are difficult to formalise at a same pace. Concept Development and Experimentation (CD&E) lifecycle (such as Phoenix in the defense area) explores new network centric capabilities using rapid system prototyping.

Ad Hoc Networking


In ad hoc networking, an efficient management needs to take in account various constraints: quality of services, topology, traffics, reliability. This management becomes more difficult when collaborative services must be supported (sensor analysis, decision making, distributed agreement, data analysis). The research approach combines constraint solving techniques with optimised link state protocols to provide new service admission schemes.

Real-time, Parallel and Distributed Systems


In modern architectures, the increasing number of processing units associated to various levels of resources (memory levels, bus) have made system design both difficult and costly. Mapping statically the set of tasks onto a multi-processor system is one of the most crucial issues, since the designer must guarantee system both feasibility and performances. These papers show how to use constraint solving and optimisation techniques to efficiently map high performance and real-time applications on parallel and distributed architectures.

Autonomous Systems


UAVs, UUVs, UGVs, planetary rovers and space probes operate with limited human intervention in changing and partially known environment. These autonomous systems navigate and manage internal behavior while responding to mission updates, threats, failures and situation awareness. Therefore, their operational performances strongly depend on the ability of the system to anticipate, adapt and react. In particular, mission planning appears to be system centric and critical for the success of challenging missions. Various theoretical and practical aspects of planning are presented, but a broad range of problems are still open.

Planning and Scheduling


Mission planning is critical phase in preparing challenging missions, in particular for first responders, space and defence operations. Mission constraints deeply impacts both plan elaboration and task scheduling processes performed by the different entities. A serie of constraint-based methods for automating mission planning and scheduling is presented in the context of Network based Operations for space and defence areas. The proposed approach can tackle complex constraint formulations, including coordinations and synchronisations.
