Cognitive Radio in Tactical Ad Hoc Networks - First Step Implementation Challenges

Abstract
Cognitive Radio (CR) has been extensively studied the past 10 years in the academia since the idea was coined by Joseph Mitola III. Among the various applications that can be addressed by the CR concept, a lot of work has been dedicated to flexible frequency management mainly due to the huge stake attached to spectrum shortage management. As a result, some new civilian standards are appearing relying on the CR concept.

CR is obviously of great interest for military applications and especially for tactical networks. Flexible management is one of the first key application since the spectrum shortage is even more stronger than in the civilian world. Moreover, CR concept can be used also to improve network performance along with frequency management. However, bringing the CR features in the military products is more complex and has its specific challenges different from the civilian market ones.

Its activities cover radio access design with cross-layer optimization for ad hoc mobile networks, and cognitive radio. He worked as Program and Technical Manager for several national and international programs since 2002. He is currently Technical Manager for a European Defense Agency program on Cognitive Radio and is participating to FP7 projects QoSMOS and FARAMIR. He is also the Technical Team Leader for the current NATO Research and Technology Group (RTG-035) entitled "Cognitive Radio in NATO" since 2008. His current research activities are focused on cross-layer content aware resource allocation for differentiated QoS including Hybrid ARQ with adaptive modulation and coding. He received the Ph.D. degree in "Signal Processing and Communications" from University of Rennes, France, in 1990. He has been elevated to the grade of IEEE Senior Member in November 2006, and was nominated Thales Expert in 2007. In October 2010, he received the national "Habilitation à Diriger des Recherches" degree.
