Abstract

Mobility and physical-layer protection is one of the challenging research issue in vehicular ad-hoc network. A network mobility (NEMO)-based vehicular ad hoc network (VANET) is a new approach to integrate the NEMO protocol with VANETs. This integration supports communications between roadside units (RSUs) and vehicles and provides Internet access through public hotspots located inside public transportation systems. Passengers inside these public transportation systems enjoy full Internet access by using different mobile network nodes (MNNs), such as cell phones and personal digital assistants. physical-layer attackers can easily localize the MNNs by measuring their received signal strength (RSS). By modifying obfuscation, i.e., concealment, and power variability ideas and propose a new physical-layer location privacy scheme, i.e., the fake point–cluster-based scheme, to prevent attackers from localizing users inside NEMO-based VANET hotspots. The proposed scheme involves fake-point- and cluster-based sub schemes, and Nested NEMO, and its goal is to confuse the attackers by increasing the estimation errors of their RSSs measurements and, hence, preserving MNNs’ location privacy and in which MNNs are controlled by an MR, which, in turn, is controlled by another MR
