METHOD AND APPARATUS FOR LOCATION AWARENESS USING REFERENCE NODES DISTANCE DECISION ALGORITHM IN SENSOR NETWORKS

摘要

The present invention relates to a position recognition method and apparatus using the appropriate distance determination algorithm of the reference nodes in the sensor network, including a reference node and a sensor node. First, by performing the algorithm for determining the spacing of the reference nodes to be located in order to satisfy a maximum error range arbitrarily set by the user, it is determined the distance to the reference nodes to be located, is created at the same time the location-aware table. Then, the sensor node may request location information to the reference node, to receive location information corresponding to the signal containing the location notification table transmitted from reference nodes In aware of their position as necessary. As another exemplary embodiment, the sensor node without requiring the transmission of the location notification table, receiving the position estimate of the sensor node calculated from the reference node directly transmitted can recognize its own position. ; A reference node, the sensor node, the location notification table, the location information request signal
