Transportation systems relying on vehicles to collect data for services such as road condition
monitoring are vulnerable to malicious vehicles injecting large amounts of fake data. A …

Knowledge of the location of vehicles and tracking of the routes they follow are a
requirement for a number of applications. However, public disclosure of the identity and …

Future cooperative transportation systems will be highly dependent on correct situation
awareness that can be established with the help of inter-vehicular communication. Location …

As wireless networks become increasingly ubiquitous, the demand for a method of locating
a device has increased dramatically. Location Based Services are now commonplace but …

A number of vehicular networking applications require continuous knowledge of the location
of vehicles and tracking of the routes they follow, including, eg, real-time traffic monitoring, e …

Relative location information helps build vehicle topology maps. Such maps provide location
information of nearby vehicles to drivers. In building a vehicle topology, one must consider …

Location-based services allow mobile device users to access various services based on the
users' current physical location information. Path-critical applications, such as supply chain …

A variety of location-based vehicular services are currently being woven into the national
transportation infrastructure in many countries. These include usage-or congestion-based …

In Vehicular Ad Hoc Networks (VANETs), nodes periodically share beacons in order to
convey information about identity, velocity, acceleration, and position. Truthful positioning of …

We propose a new approach for securely verifying sequences of location claims from mobile
nodes. The key idea is to exploit the inherent mobility of the nodes in order to constrain the …
