Abstract:
The Intelligent transportation system (ITS) aims to
improve the performance of the transportation systems.
Vehicular ad hoc networks (VANETs) are the potential
mechanism by which ITS can realize its goal. VANET supports
the idea of communication among moving vehicles. The next
generation Vehicles is equipped with many embedded sensors,
high processing power and wireless communication capabilities.
These communication and computing capabilities has potential
to enhance transportation safety, efficiency and provide
infotainment while on the road. In VANET moving vehicles form
ad-hoc networks through wireless connection for exchanging
critical information. Safety related information dissemination is
one to many communication, so multicasting or broadcasting
schemes are utilized for information dissemination. Delivery of
safety related messages must be fast and reliable. This criterion
draws the researchers' focus to develop efficient dissemination
schemes. This review paper discusses safety related data
dissemination strategies, along with comprehensive
classification, challenges and future research direction.
