Abstract:

The positioning problem arises when it is necessary to locate a set of geographically-distributed objects using measurements of the distances between some object pairs. In a Packet Radio Network, for instance, any two network members that can talk to each other may use a simple time-stamping mechanism to measure the distance between them a distance measurement protocol may then be developed. The problem is whether and how the distance measurements can be used to determine the geographical location with respect to a given system of coordinates. A knowledge of the precise location of each network node is crucial to the operation of Distributed Sensors Networks. The data collected and interpreted only if we know their precise location. A position-locating system may be invaluable to the operation of a fleet of vehicles, each equipped with a Packet Radio Unit. For example, monitoring the location of a fleet of security vehicles, aircraft, a tank division, or a flock of missiles could all be assisted by a position-locating system. Clearly a positioning system would be an important service to Packet Radio Network users.
