Research and Design of Indoor Positioning System
Abstract: The IEEE802.15.4 standard based on ZigBee technology is a new low of short distance wireless communication technology, it has the advantages of low rate, low cost and low power consumption. Through the research of wireless sensor network, this paper designs the indoor positioning system based on ZigBee technology, the system consists of reference node, location node, gateway and terminal computer, and uses the received signal strength indicator (RSSI) algorithm to Calculate the location node coordinates. Finally, the experimental results were simulated, the results show that the system good positioning effect.
Key words: ZigBee; Gateway; Indoor positioning algorithm; RSSI
