In order to meet the need of book management in smart library and achieve the positioning of perception node for book position, ZigBee wireless smart network technology is adopted to achieve the information interaction of book information and book management, and RFID technology is used to provide communication perception platform for monitoring book node. Least square method and RSSI (Received signal strength indication) are used to achieve the optimized 3d positioning for book node. The simulation result shows that the amount of calculation for the algorithm is small, whose positioning accuracy reaches 1.21%.
