ABSTRACT:
Provided is an apparatus and method for collaborative location awareness based on weighted maximum likelihood estimation (MLE), which is configured to improve accuracy of location awareness between nodes in estimating a location of a blind node. The method includes exchanging location awareness information with a reference node and a location-estimated blind node among peripheral nodes when location awareness is requested, performing location estimation based on weighted MLE, performing location calculation by using the location awareness information and an estimate obtained through the location estimation, and providing location awareness results of blind nodes.
