Abstract :
This paper presents wireless localization networks for locating stationary object in an indoor office environment. Actual experimental test results based on UWB (IEEE 802.15.4a), WLAN (IEEE 802.11), and ZigBee (IEEE 802.15.4) are briefly presented and advantages and disadvantages of each method are also addressed. A new method based on received-signal strength index (RSSI) of radio signals emitted from fixed reference nodes is outlined. In the new method, mobile reference tags are used to detect signal strength accurately so that reliable signal propagation model can be produced.
