A Novel Privacy Preserving Localization Scheme based on Lateration for Mobile User Concentrated Networks

Abstract

Location tracking and preserving in wireless networks are tedious as the network consists of infrastructure less devices that change their position more frequently due to acquired mobile patterns. In such networks, malicious users may prevail to snatch information by hiding their location and other spoofing other user information. STAMP is designed for ad-hoc mobile users generating location proofs for each other in a distributed setting. However, it can easily accommodate trusted mobile users and wireless access points. STAMP ensures the integrity and non-transferability of the location proofs and protects users' privacy. But STAMP does not ensure localization accuracy and time for switching user location. A new Lateration based Privacy preserving and Transmission Scheme (LPTS) is proposed for wireless networks to improve localization accuracy. Besides, trust group based verification improves secure transmission over the network minimizing errors in communication.
