Analysis of Wireless Link Characteristics in RFID Location-network

Junhuai Li, Guomou Zhang, Wei Wei, Zhixiao Wang and Jing Zhang

RFID-based location awareness is becoming the most important issue in many fields in recent years, such as ubiquitous computing, mobile computing. However, the RF system is noise-limited, which leads to the readers can’t read the information from tags timely and accurately, especially for RFID localization network. This study proposed a novel RFID indoor localization method based on Received Signal Strength Indicator (RSSI) and Packet Received Ratio (PRR). To do so, the environmental factors affecting the link quality are analyzed and the location awareness data is collected by RFID equipment using non-coherent Frequency Shift Keying (FSK) as modulation scheme and Not Return to Zero (NRZ) as encoding scheme. Then the relationship model between RSSI, PRR and distance is established based on the classic radio propagation model in localization field and theoretical analysis of the normal probability distribution of PRR is conducted. The experimental results show that our approach is valid and proper and also contributes to a novel perspective and theoretical support on the further study and application of RFID indoor localization.
