Energy Efficient Non-Cooperative Methods for Resource Allocation in Cognitive Radio Networks

In a cognitive radio network wherein primary and secondary users coexist, an efficient power allocation method repre-sents one of the most important key aspects. This paper provides a novel approach based on a game theory framework to solve this problem in a distributed and fair way. Formulated as an optimization problem, the resource allocation prob-lem between secondary users and primary users can be modeled and investigated with the Game Theory, and in par-ticular S-Modular Games, since they provide useful tools for the definition of multi objective distributed algorithms in the context of radio communications. This paper provides also a performance comparison among the proposed game and two other algorithms, frequently used in this context: Simulated Annealing and Water Filling
