Computing Nash Equilibrium in Wireless Ad Hoc Networks: A Simulation-Based Approach [PDF]
Electronic Proceedings in Theoretical Computer Science, 2012 This paper studies the problem of computing Nash equilibrium in wireless networks modeled by Weighted Timed Automata. Such formalism comes together with a logic that can be used to describe complex features such as timed energy constraints.
