An Effective Strategy for Trusted Information Scheme for Location Privacy in VANETs

VANET can be formed by connecting vehicles with internet access by drivers. Vehicles running with different speed, directions and locations can form ad-hoc network to solve various problems in human life such as traffic management, safety in transportation, utilization of transport resources and many ad-hoc applications for mobile users. Method used for protecting such as clustering, anonymization, fake point location privacy etc. are proposed by different authors. It is important to see that the vehicle’s or group of vehicle’s location privacy needs to be protected. In this paper we are retracing the technique used for location privacy in VANET and propose the novice Ad-hoc Trusted Information Exchange method for location privacy. Keywords— VANET, location privacy, ad-hoc trust, mobile security, LOR INTRODUCTION Basically VANET is an application of MANET which can be formed by connecting vehicles with internet access by drivers. It plays important role in traffic management and safety driving. In VANET, each vehicle is embedded with OBU (on board unit) and AU (application unit) as shown in fig.1. Where OBU has communication capability and AU is used to execute a program made for OBU’s communication capability. Road Side Unit (RSU) can be attached to the infrastructure network which is connected to the internet. VANET provides two types of communication: Fig 1: VANET Architecture International Journal of Engineering Research and General Science Volume 3, Issue 1, January-February, 2015 ISSN 2091-273
