WALL FINDING FOR WIRELESS LIGHTING ASSIGNMENT

摘要

A method for determining the location of partition walls within a building uses a wirelessly interconnected network of nodes to determine relative spatial positions of selected nodes using (i) received signal strength indication (RSSI) values and time of flight (ToF) values, both indicative of a distance of separation between two communicating nodes. A first map of the network topology is derived from the RSSI values and a second map of the network topology is derived from the ToF values. The RSSI values are affected by building partition walls whereas the ToF values are relatively unaffected by partition walls. A comparison of the first and second maps is used to determine the location of partition walls within the building.
