Abstract
A position estimation server estimates the position of a target mobile node by using position information of a minimum number of anchor nodes knowing their position, distance information estimated between mobile nodes or between the anchor nodes and the mobile nodes, and connectivity information.
Claims16
A method for estimating the positions of a plurality of mobile nodes by a position estimation server, the method comprising:
- receiving at least one information required for position estimation, among the position information of at least two anchor nodes knowing their position, connectivity information between the anchor nodes and mobile nodes, distance information estimated between the anchor nodes and the mobile nodes, and distance information estimated between the mobile nodes;
- and
- estimating the position of at least one target mobile nodes of the plurality of mobile nodes by using the at least one information required for position estimation.
A server for estimating the positions of a plurality of mobile nodes, the server comprising:
- an information collector which receives, from one of at least two anchor nodes knowing their position, at least one information required for position estimation, among position information of two anchor nodes, connectivity information between the anchor nodes and the plurality of mobile nodes, distance information estimated between the anchor nodes and the mobile nodes, and distance information estimated between the plurality of mobile nodes,
- an estimator which estimates the positions of the plurality of mobile nodes by using the at least one information required for position estimation
