Abstract:-Wireless Mobile Ad Hoc Networks are particularly vulnerable due to their fundamental
characteristics such as an open medium, dynamic topology, distributed cooperation, Vehicle-tovehicle/vehicle-to-infrastructure(V2X) communication systems are envisioned to greatly improve road safety,
traffic efficiency, and driver convenience. However, many V2X applications rely on continuous and detailed
location information, which raises location privacy concerns. A multitude of privacy protection mechanisms
have been proposed in recent years. However, few efforts have been made to develop privacy metrics, which
can provide a rigorous way to assess the privacy risk, evaluate the effectiveness of a given mechanism, and
exploit the full possibilities of protection methods in V2X systems. Therefore, in this paper we present a tripbased location privacy metric for measuring user location privacy in V2X systems. The most distinguishable
aspect of the metric is to take into account the accumulated information, which is the privacy-related
information acquired by an adversary for an extended period of time, e.g., days or weeks. We develop methods
to model and process the accumulated information, and reflect the impact on the privacy level in the metric. We
further prove the viability and correctness of the metric by various case studies. Our simulations find out that
under certain conditions, accumulated information can significantly decrease the level of user location privacy.
The metric and our findings in this paper give some valuable insights into location privacy, which can
contribute to the development of effective privacy-protection mechanisms for the users of V2X systems. and
constrained capability. Location information of nodes can be critical in wireless ad hoc networks, especially in
those deployed for military purposes. In this paper, we present study of various method of receiver location
privacy in mobile adhoc network
