Towards Fault-Tolerant Co-operative ATM


As a distributed application, air traffic management control includes the possibility of partial failures, as this is an inherent characteristic of distributed applications. The fault tolerance research community has developed solutions, notably based on the concept of replication, as applied for example,to databases. However, these techniques are almost always applied explicitly and statically.

Newer, co-operative applications, such as air traffic management, are, on the contrary, very dynamic. It is nearly impossible to identify in advance the most critical agents of the application. This is because the roles and relative importance of the agents can vary greatly during the course of computation, interaction, and co-operation. As a consequence of this, our approach is to fix the capability to the multi-agent system itself to dynamically identify the most critical agents and to decide which fiabilisation strategies to apply. This approach is analogous to load balancing but applied to reliability.

Start date and duration

This project started in December, 2006, and was stopped at the end of the first year, the feasibility phase.


Our partners/contractors were:
  • the Laboratoire d'Informatique de Paris 6 (France), the main contractor; and
  • the Laboratoire d'Informatique, de Robotique et de Microelectronique de Montpellier (France), a sub-contractor.
