N2 - IEEE 802.15.4, the basic standard behind ZigBee, is a low-power communication standard mostly operating in the free 2.4 GHz Industrial, Scientific and Medical (ISM) frequency band. This band is heavily used by many technologies sending with more power, therefore avoiding interference is an important task and knowledge of the spectrum is essential. This paper presents an algorithm and its actual implementation that classifies sources of interference from a Received Signal Strength Indication (RSSI) noise floor reading of a single IEEE 802.15.4 channel. This algorithm can identify WLAN and Bluetooth traffic as well as the interference generated by microwave ovens with a second of RSSI measurements. It can run on off-the-shelf sensor node hardware. Since there is no need to change the channel, the node is continuously connected to its network with full message receiving capability.
