In this paper, the primary objective is to discuss the details of scalable methods for distributing certificate revocation lists and other large files using vehicle-to-vehicle and vehicle-to-infrastructure communications while taking advantage of the multi-channel operations in IEEE 1609.4. We also discuss the results from a simulation study using the ns-3 network simulator to closely replicate the...
This paper describes a novel idea for distributing certificate revocation lists (CRLs) in a vehicular ad hoc network (VANET) scenario. The idea, Most Pieces Broadcast (MPB), takes advantage of the two distinct channel types in VANETs while reducing contention for the wireless medium. Broadcast methods that reduce wireless medium contention in VANETs are highly desirable to assist in keeping the medium...
