A computer-implemented method includes identifying one or more tag readers. The one or more of tag readers are positioned peripherally to a region. The computer-implemented method further includes receiving a signal, by at least one of the one or more tag readers, from a tag. The computer-implemented method further includes determining a received signal strength indication for at least one of the one or more tag readers and mapping at least one received signal strength indication onto at a one dimensional representation of the region to yield a mapped data. The computer-implemented method further includes performing pattern recognition on the mapped data to yield a pattern data and applying machine learning to the pattern data to locate the tag within the region. A corresponding computer system and computer program product are also disclosed.
