Securing vehicular ad-hoc networks connectivity with roadside units support

This paper evaluates three inter-vehicle spacing models based on exponential, Generalized Extreme Value, and Exponential with robustness factor statistical distributions [1], [2], [3]. Vehicles adjust transmission range as a function of its spatial density on a road segment to increase its network connectivity with other vehicles. This connectivity can be secured by deploying this scheme [4] which secures communications among vehicles through trusted road-side units that distribute secret keys to vehicles under their coverage.
