If the leaked location is coarse-grained, the risk of data leakage is medium because the attacker needs to probe more data and use trilateration
positioning to get people's relatively precise locations.
When a User Node (UN) enters an area, where it can obtain at least 3 ranging measurements to 3 distinct NN of a LRF, a trilateration
algorithm can be performed and a solution for its relative position inside LRF can be obtained.
In parallel, selected sensor nodes calculate target location locally using trilateration
The Angle of arrival will be used for the Angle Measurement(AOA).so this Method is best when compared with the Trilateration
scheme where node position will be measured from the multiple reference points by using the TOA(Time of arrival).
Finally, students learn how communications between multiple satellites and a ground-based, handheld unit use the r x t = d relationship along with trilateration
to lock in a location.
The LIS used in this paper is called i-Tracer, it is developed by least-squares trilateration
(LST) algorithm .
ML Mulilateration technique is employed in place of Trilateration
if the distance measurements are noisy as Trilateration
cannot give accurate results in such conditions.
Given the locations of the anchors and the correction factor, a node is then able to perform trilateration
to estimate its own location.
Another interesting thing--GPS operates through a system of satellites that transmit radio signals to the user's receiver where a trilateration
is performed to determine a position based on the time difference of arrival of those signals.
When the distance from the moving node to at least three fixed nodes is known, the location of moving node can be calculated with trilateration
In a matter of seconds, through the use of complex trilateration
, your exact location on or around earth is pinpointed.
The methods to create the micro-network are triangulation, trilateration
, levelling or trigonometric high.
