Survey of Vehicle Ad-Hoc Network
In car network enable the direct communication in ad-hoc network among the car and between the car and road side communication device. the ad hoc networking provides a spontaneous and direct communication of a car with other cars or with fixed road-side access points in its vicinity. The communication is done in between cars that are based on the short range wireless technology. It become safety road and travel comfort using ad-hoc network. The authors see the different to communication mode in car network. Also they see the Geo-networking with car network. IPv6 is considered as the most appropriate technologies to support communication in VANET thanks to its extended address space, enhanced mobility support, ease of configuration and embedded security.
