ABSTRACT
Vehicular ad hoc networks are a special type of mobile ad hoc networks in which vehicles have processing and wireless communication capabilities. The idea is that vehicles are able to establish communication under different environments, such as urban centers and highways, in order to cooperatively increase road safety and efficiency and provide entertainment to passengers. The study to look at computer networks as social networks has been increased, because these are networks that link people, organizations, and knowledge. The use of social metrics to improve the performance of protocols and services in ad hoc networks has received much attention by the research community. Under dense road traffic conditions, when a vehicle receives a data message, it must carefully decide whether to rebroadcast it, and when to rebroadcast it in order to avoid redundant retransmissions and, consequently, the broadcast storm problem.
