Cooperative Cognitive Systems
Lorenza Giupponi, Christian Ibars · InTech eBooks · 2009
In this chapter, we have described how cooperation can benefit the different phases of the so called cognitive radio cycle. In particular we have focused on physical layer cooperation, showing that benefits can be obtained for both the primary and the secondary system in terms of spatial diversity, increased range and increased availability. In addition, we have modeled the critical interference management problem in a cooperative and cognitive system through a game theoretical approach, as well as providing design guidelines for games with good convergence characteristics, in both cases of complete and incomplete information.
