1. An apparatus for collaborative location awareness based on weighted maximum likelihood estimation (MLE), comprising: a transceiving unit configured to transmit/receive location awareness information; a location estimating unit configured to perform location estimation of a specific unit block in a network by using weighted MLE on the basis of the location awareness information; a location calculating unit configured to calculate a location of a blind node by using the location awareness information and an estimate of the location estimating unit; and a location awareness unit configured to perform collaborative location awareness between the location-calculated blind node and peripheral nodes and calculate overall locations of the nodes.
