Survey on Privacy Preserving Scheme for Hotspots in VANETS

Balasubramanian.C , Vijayalakshmi.G

Vehicular Ad-hoc NETworks (VANETs) has more significant interest and growing with the today‟s research efforts towards protecting the network from attackers to reach the adequate level, for the drivers and manufacturers to attain infotainment and safety of life. Due to open nature of wireless network, the adversary can easily attack the networks. The vigorous VANET has the need of dependability with their privacy and security features. Nested NEMO based VANETs (NN-VANETs) is a new approach that combines the NEMO protocol with VANETs. NN-VANET has the challenge of high routing delay. The study examines the incidence of physical layer attack and the various preserving technique by studying the existing research ideas and modify them like modified obfuscation technique and power variability ideas to increase the privacy as high. This paper concludes with possible future research fields of privacy preservation.methodologies used to preserve the privacy at physical layer. The existing research work has some inconsistencies, limitations or problems while achieving the privacy by using the existing techniques such as changing power and obfuscation techniques. The main goal of this survey is to propose a new privacy
