Abstract
A node for self localization, a clustering method using the same, and a localization method are provided. The node, which is located in a specific space so as to constitute a sensor network, includes a location information messaging unit which receives one or more location information messages including information on spatial locations of one or more neighboring nodes in the sensor network from the neighboring nodes in the sensor network; a distance calculator which calculates a first distance to the neighboring node on the basis of the location information included in the received location information messages and calculates a second distance to one or more neighboring nodes on the basis of the received time or intensity of the message on the location information; and a clustering unit which forms clusters of the node and a plurality of neighboring nodes in which the difference between the first and second distances is less than a predetermined threshold.
