An overview of WSN and RFID network integration

Wireless Sensor Network (WSN) and Radio Frequency Identification (RFID) systems represent two key technologies. They have attracted considerable attention in recent years for ubiquitous computing and their use revolutionizes diverse applications in current and future system. RFID provides unique identity to the objects while WSN gives information about the physical condition of the objects. Hence, the integration of these technologies can expand their overall capacity and functionality in a range of engineering and scientific fields. WSN and RFID integrated systems provide excellent infrastructure to process, acquire and distribute data in dynamic environment. The integration of RFID and WSN is an emerging technology which utilizes identified advantages of both systems thus making it more efficient and reliable. In this paper, a brief idea is given about the requirements to be considered for the integration of WSN and RFID network. Basic architectures of WSN and RFID integrated network are discussed. An abstract of these architectures is been provided and their respective advantages and disadvantages are been specified.
