LOCATION SYSTEM FOR STREET LIGHT MONITORING
Abstract
A street light monitoring system has a small fraction of the street lights in the system being anchor nodes that are configured to detect and store their own actual fixed position, thereby acting as reference points. Further, the other street lights are referred to as blind nodes and do not have their actual fixed position but can derive their position using the coordinates of the anchor nodes and estimating their distance to them. The distance estimation for any blind node can be performed using a received signal strength indication (RSSI) measured at the respective blind node for small distances of up to a threshold value and a link quantization technique takes advantage of the typical placement of the street lights. Inferred distances between the street lights can be assigned to pre-determined categories of distances for a coarse estimation and further position adjustment to a closest possible “real” position.
