Intelligent lighting control system

A central controller for remote communication with a plurality of network controllers (NC), the plurality of NCs being provided in communication nodes and being configured for near field communication with each other, the central controller being configured to be in communicative connection with each NC of the plurality of NCs, the central controller comprising:

• a data processing device connected to a communication module, wherein the data processing device processes and analyzes information received from the communication module;
• wherein the central controller is configured to:
• receive ID information, position information and a list of communicable neighboring NCs from each NC of the plurality of NCs,
• maintaining a list of reporting NCs,
• maintaining a further list of NCs based on the received lists of communicable neighboring NCs,
• crosschecking the list and the further list to identify NCs appearing only in the further list and thereby indicating missing or not reporting NCs,
• receive precision information from each NC of the plurality of NCs,
• based on the received ID information, position information and precision information and the received lists of communicable neighboring NCs identify at least one NC of the plurality of NCs as providing accurate position information and use the thus identified NC as an anchor point NC, and
• identify position drifting NCs by analyzing the received ID information, position information and precision information and the received lists of communicable neighboring NCs.
