Cooperation Behavior of Vehicles in an Evolutionary Game for Information Dissemination
Résumé
In this paper, we study the cooperation behavior of
vehicles in a VANET (vehicle ad hoc network) for information
dissemination. Any vehicle is only allowed to adopt one of two
strategies at the same time: cooperation (forwarding) or defection
(dropping), and may change its strategy periodically.We consider
the scenario that the incentive for cooperation of any vehicle is
controlled according to evolutionary game theory, so that any
node only learns its new strategy from its neighbors. Through
simulations, we illustrate that, how different parameters, such
as node degree, information dissemination amount, information
dissemination scheme, channel accessing probability, affect the
incentive to be a cooperator for each vehicle in the network.
