A game theoretical approach to evaluate cooperation enforcement mechanisms in mobile ad hoc networks

In this paper we propose two methods to evaluate the effectiveness of the CORE mechanism based on a cooperative game approach and a non-cooperative game approach: the results obtained using the first approach define a lower bound on the number of legitimate nodes in an ad hoc network when the CORE mechanism is adopted while the second approach describe the asymptotical behavior of a selfish node that is controlled by CORE.
