Today, ITS (Intelligent Transport Systems) is paid attention by people all over the world. ITS is the system that solves the road traffic problems by using communications technology of vehicles.IVC ( Inter Vehicle Communications ) is the communications technology that vehicles exchange the information by using wireless LAN without any base stations. VANET ( Vehicular Ad-hoc NETwork ) have been expected to provide new applications for passengers of vehicles, by enabling vehicles to communicate with each other via IVC as well as with roadside base stations via RVC ( Roadside-to-Vehicle Communications ). We propose the COC (Contents Oriented Communications) system on VANET via IVC. With COC, each vehicle collects original information that each vehicle has by communicating each other, and creates contents which may be useful for drivers, by analyzing original information. COC deliver the analyzed contents to other vehicles. The simulation results show that COC provide timely information of vehicular accidents and congestion to drivers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
