- Recently, RFID/USN is one of fundamental technologies in information and communications networks. Low-Rate WPAN, IEEE802.15.4 is a low-cost comunication network that alows wireles conectivity in applications with limited power and relaxed throughput requirem ents. Its applications are building lectronics, and so on. Some applications require location information. Of course location awareness is u seful to improve usability of data. Low-Rate WPAN is regarded as a key specification of the sensor network with the characteristics of orking, and etc. Unfortunately ZigBe aliance propose a lot of aplications based on location aware technologies, but the specification and low-rate WPAN devices don’t suport anything about location-bas ed services. RSSI (Received Signal nel selection, and etc.RSSI is used to find the location of a potable device in WLAN. In this paper we studied indoor location awarenes using vector matching of RSSI in Low-Rate wi reless PAN. We analyzed the location awareness. We implemented sensor nodes with diferent shapes and configured the sensor ne twork for the location awareness with 4 fixed nodes and a mobile node. We try to contribute developin g location awareness method using RSSI in 3-dimension space.
