Light pole localization in a smart city

Many smart city lighting applications require information about the location of light poles, in particular about which light poles are neighbors along the street with respect to passing traffic. This paper addresses the problem of deriving the topology of light poles in a smart city, relying only on the data gathered from Passive Infrared Sensors attached to the light poles. A statistical algorithm is presented and evaluated based on a data set gathered from a real deployment in a residential area.
