Network architecture and energy analysis of the integration of RFID and Wireless Sensor Network

Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) are two important components of ubiquitous computing. They have different advantages and application areas. The RFID sensor network, which integrates RFID into WSN, has both the advantage of RFID and WSN. In this paper, three common and one new compound network architectures are described in detail. Targeting RFID sensor network systems, which use distribute smart node network architecture and applies Basic Frame Slot Aloha (BFSA) as the MAC protocol for smart node to reading tags, the energy model and energy consumption of the smart node are proposed and analyzed. We use quantitative methodology to evaluate the energy consumption of a smart node, as well as give our computing formula to evaluate the lifetime of the smart node, and its feasibility is discussed thoroughly.
