Abstract:

Vehicular Ad hoc Network(VANET) is a highly mobile self-organizing network,and it has three architectures:Vehicle-to-Vehicle (V2V),Vehicle-to-Infrastructure (V2I),and hybrid architecture.Due to the fast-moving and dynamic change in the topology of the VANET nodes,the collection of reliability,secure,and real-time data is a research hotspot.This paper discusses the data collection based on the on-board devices/sensor,the routing protocol,and extraction;analyses the characteristic of those methods and their future development;and finally compares the applications and performance the methods.

Key words: ITS;Ad Hoc network;data collection
