Classification: CPC H  Y | IPC H

Claim 4:
5. The central controller according to claim 1, wherein the central controller is further configured to identify a position drifting NC by:
requesting and receiving updated position information, precision information and list of communicable neighboring NCs from each NC of the plurality of NCs,
retrieving near-field settings and local communication range of each NC of the plurality of NCs,
select at least one NC in the list of communicable neighboring NCs of the anchor point NC,
calculate the distance of at least one NC in the list of communicable neighboring NCs to the anchor point NC,
determine whether the calculated distance of the at least one NC is smaller than the local communication range of the at least one NC, and, if the calculated distance of the at least one NC is not smaller than the local communication range of the at least one NC determine that the at least one NC is position drifting.
