Strong coordination and strategic communication in the finite-length regime
Since the new generation of wireless networks comprehends a unified network of connected objects, it is vital to ensure the cooperation and coordination of the constituent devices. While communication networks have traditionally been designed with the purpose of reliably conveying information, the devices can be viewed as autonomous decision makers which exploit communication as a way to enforce a prescribed behavior. In this scenario, the information transmission is affected by at least two kind of constraints. First, the encoder and the decoder of a given signal may have nonaligned incentives, in which case the encoder might be unwilling to transmit truthful information. Second, communication between agents is often imperfect, the encoder signal is degraded by ambient noise.
By building on recent advances on strong coordination in , on finite-length regime , on security  and on strategic communication in [4, 5], we will develop a general framework for the strong coordination of the actions of strategic agents in the finite-lenght regime. New asymptotical bounds will be drawn using techniques similar to the ones employed in , the fixed-length regime will be tackled following the approach of [7, 8, 9].
This PhD will take place at IRISA UMR 6074 in ERMINE team, Campus de Beaulieu, 263 Boulevard du General Leclerc, 35000 Rennes, France, with regular scientific visits at IMT Nord-Europe, via Guglielmo Marconi, 59650 Villeneuve-d’Ascq (Lille), France. The starting date will be September / October 2023 (negotiable if necessary).
Applicants should have a strong background in mathematics, either in the theoretical aspects of telecommunications, or in game theory. Moreover, applicants must have an Msc degree (M2, engineer degree or equivalent in France). A good and working knowledge of the English Language is required.
