Ecological Dynamics and Evolution of Cooperation in Vehicular Ad Hoc Networks

In Vehicular Ad Hoc Networks (VANETs), promoting cooperative behavior is a challenging problem for mechanism designers. Cooperative actions, such as disseminating data, can seem at odds with rationality and may benefit other vehicles cost to oneself. Without additional mechanisms, it expected that in the population will decrease eventually disappear. Classical game theoretical models cooperation, public goods game, predict this outcome, but they assume fixed sizes overlook ecological dynamics of interacting vehicles. paper, we propose an evolutionary incorporates VANET offers new insights cooperation. Our model considers free spaces, density, departure rates vehicles, randomly composed groups each data sender. Theoretical analysis simulation results show higher densities rates, due minimum differences between pay-offs promote behavior. This feedback leads interesting results. proposed demonstrates extension varying densities. We possible cooperation VANETs without need any supporting mechanisms. Future research investigate potential using practical settings.
