An Electronic Shelf Label System Based on WSN

Traditional paper labels on the supermarkets shelves are of many shortcomings such as the high error rate, high losing rate, increasing cost and unrealizable realtime-updating caused by manual management. In order to overcome these shortcomings, this paper aims to design a new Electronic Shelf Label system. Firstly, the overall framework is introduced. Then an ultra-low-power ESL and wireless communication base station modules are studied respectively. The MAC and router protocols are also designed based on Wireless Sensor Network (WSN) to meet the requirement of low power consumption and real-time price update. The Electronic Shelf Label system can improve the efficiency of the label management greatly and enhance customers experiences thus has a wide prospect of application.
