Towards Intelligent Control of Beaconing Power and Beaconing Rate in Vehicular Ad Hoc Networks

Abstract

In this paper, to avoid congestion in the wireless channel of vehicular ad hoc networks (VANETs), a joint beaconing rate and beaconing power based on game theory are proposed in this paper. The game is formulated as a non-cooperative game, a Bayesian game, and a cooperative game. Three distributed and iterative algorithms (Best Response Algorithm, Fictitious Play Algorithm, and Cooperative Bargaining Algorithm) are proposed for computing the beaconing power and beaconing rate of each vehicle. Extensive simulations show the convergence of a proposed algorithm to the equilibrium beaconing power and beaconing rate and give some insights on how the game parameters may vary the game outcome.
