AUTO-DISCOVERY OF NEIGHBOR RELATIONSHIPS AND LIGHTING INSTALLATION SELF-MAPPING VIA VISUAL LIGHT COMMUNICATION

摘要

Networked intelligent lighting devices may utilize visual light communication to perform autonomous neighbor discovery, for example, as part of a map generation process. Individually, each intelligent lighting device within an installation transmits a series of packets via visual light communication for receipt by one or more of the other intelligent lighting devices. Receiving intelligent lighting devices record the number of received packets from each transmitter. Records of numbers of received packets are conveyed via a data communication network to a centralized process. The centralized process utilizes the conveyed records to determine neighbor relationships between lighting devices, for example to generate a map of devices as located within the installation.
