In some examples, a computing device may receive sensed data information sent in a transmission by a first sensor, the sensed data information including a sensor identifier and sensed data of a first sensor. The computing device may associate a first timestamp with the sensed data information. Further, the computing device may receive, from other sensors, radio signal strength information including signal strength data related to the transmission and a second timestamp corresponding to detection of the transmission. The computing device may determine a location of the first sensor based on the signal strength data received from the other sensors. In addition, the computing device may associate the location with the sensor identifier of the first sensor based on comparing the first timestamp with the second timestamp. In some cases, one or more second sensors may forward the transmission from the first sensor to the computing device.
