Secure connectivity in platoon-based vehicular networks

Abstract： Platoon-based driving has been proved to effectively improve road capacity and energy efficiency. On this basis, this paper investigates wireless connectivity of platoon-based vehicular networks with the presence of eavesdroppers. Three types of secure connectivity probability, intra-platoon secure connectivity probability, extro-platoon secure connectivity probability and network secure connectivity probability, are defined and derived to respectively characterize the network constituted by a single platoon, a double platoon and multiple platoons. Simulation results show that system parameters affecting connectivity performance include transmission range, number of eavesdroppers and vehicle density. Particularly, secure connectivity probabilities are maximized by an optimal vehicle density.
