Abstract

So far, the problem of positioning and distance measurements in wireless networks has been studied in a non-adversarial setting. In this work, we analyze the resistance of positioning techniques to position and distance modification attacks; we propose two mechanisms for the position verification, based on multilateration and Time Difference Of Arrival (TDOA) techniques. We further propose two mechanisms for verification of nodes' mutual distances; we base these mechanisms on GPS and radar technologies. In our mechanisms, we make use of conventional distance estimation and cryptographic techniques.

Global Positioning System

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

Indoor positioning system

An indoor positioning system (IPS) is a network of devices used to locate people or objects where GPS and other satellite technologies lack precision or fail entirely, such as inside multistory buildings, airports, alleys, parking garages, and underground locations. A large variety of techniques and devices are used to provide indoor positioning ranging from reconfigured devices already deployed such as smartphones, WiFi and Bluetooth antennas, digital cameras, and clocks; to purpose built installations with relays and beacons strategically placed throughout a defined space.

Positioning system

A positioning system is a system for determining the position of an object in space. One of the most well-known and commonly used positioning systems is the Global Positioning System (GPS). Positioning system technologies exist ranging from worldwide coverage with meter accuracy to workspace coverage with sub-millimeter accuracy. Interplanetary-radio communication systems not only communicate with spacecraft, but they are also used to determine their position.
