A GRID BASED SECURED ON-ROAD LOCALIZATION SYSTEM WITH LINER ERROR PROPAGATION USING VANET AODV PROTOCOL

GPS navigators has widely adopt by drivers. However, due to this sensibility of GPS signals to terrains, vehicles cannot to get their locations, when they are anyone inside a tunnel or a road it’s surrounded by high rises, where satellite signal is ended. This mainly used for safety and convenience problems. But the VANETS advance into their critical areas and to become more dependent on these localization systems. GPS is starting to locate some uncertain problems, such not always being the available or not being robust enough for this some different applications. For the reason, a number of other localizations techniques such as Cellular Localization, Dead Reckoning, and Image Video Localization have been used in VANETs to overcome the GPS limitation. To address this issues, to proposes a novel Grid based On road localization system (GOT), where these vehicles with and without accurate of GPS signals self organizes into a Vehicular Ad Hoc Network (VANET), exchange the locations and distance information and helps to each other’s to calculate an accurate position for all these vehicles inside the network. The location information’s can be exchanged among vehicles one or multiple hops away in this paper.
