A Comparative Survey on Information Dissemination in Heterogeneous Vehicular Communication Networks

The integration of affordable wireless communication devices to vehicles have been a key component to enhance road safety. The connected vehicles aim to provide intelligent communication amongst vehicles as well as vehicles and roadside units to enhance safety. A self-organizing network of connected vehicles is termed as Vehicular Ad-Hoc NETworks (VANETs). VANETs can significantly improve road safety by sharing critical information amongst vehicles. Information dissemination plays a critical role in vehicular communication for sharing time critical safety information. In this paper, we have provided a comparative analysis of information dissemination approaches for vehicular communication. Also, we have presented the issues related to the heterogeneous vehicular communication environment.
