摘要：To track the correct location of a mobile user is a critical role for location services in an indoor environment. Low complexity, low power and low cost are the sole characteristics of wireless sensor network. Indoor position system performance can be improved drastically with these properties. Scattering diffraction, and reflection has adverse effect on radio signal propagation, therefore the received signal strength requires good calibration method to provide correct position. Grey prediction method is used in this paper for wireless sensor network and it makes use of wireless techniques (Zigbee/802.15.4). Grey prediction predicts Received Signal Strength Indicator (RSSI) and Dynamic triangular (DTN) location method is also designed. Mean distant error of RSSI at offline stage on mobile user can be within 2.3m for performance analysis. In run time stage, grey prediction give more exact predicted position and carries out mean distance error within 1.3 m.
