摘要： A method and system for sensorless tracking of an indoor target using a wireless distance measuring technology. A location tracking apparatus is initially moved, and then it is determined whether or not an initial traveling direction of the location tracking apparatus is forward or backward with respect to the target. A minimum distance between the location tracking apparatus and the target during the movement is determined, the minimum distance is stored, and the location tracking apparatus is moved to a location corresponding to the minimum distance, where it is determined whether the location tracking apparatus is directed forward or backward with respect to the target at the location corresponding to the minimum distance. The location tracking apparatus is then moved to the target.

摘要： A location sensing system and method for a mobile communication system is provided for maintaining location sensing service with the support of mobile nodes when there is an insufficient number of anchor nodes for reference points. A location sensing method for a mobile communication system includes discovering, at a source mobile node, anchor nodes in a vicinity; discovering, when a number of discovered anchor nodes is less than a predetermined number of reference nodes required for location sensing, neighboring mobile nodes; selecting at least one of neighboring mobile nodes as a reference mobile node; and computing a location of the source mobile node in cooperation with the predetermined number of reference nodes including the discovered anchor nodes and the reference mobile node.

摘要： An indoor location system having a sensor and a method for checking an indoor location using the indoor location system are disclosed. The method includes: calculating a current location coordinate by using nodes; calculating a first movement distance by comparing the current location coordinate and a stored previous location coordinate; calculating a second movement distance through a sensor; and storing the current location coordinate instead of the previous location coordinate when the distance between the first movement distance and the second movement distance is smaller than a predetermined threshold value. Accordingly, an accurate location of an object can be recognized indoors and an error can be prevented from being caused when the location of the object is recognized.
