Outline of Final Research Achievements

The objective of this research is to develop a set of technology to realize zero-communications power opportunistic sensor data retrieval. The feature of this research is the use of dual interface passive communication in which the communication subsystem and sensing subsystem inside a sensor share a common NVRAM. Since the sensor data is empowered and executed by passive communications. There is no need to synchronize the sensing timings and transmitting timings, which yields extremely low power consumption sensing systems. We developed virtual tag system to handle inevitable RF tag read failure. A lightweight antenna direction control provides an extended reading time. We also developed a brand new multisubcarrier transmission scheme to speed up and synchronize the sensor readings. To properly interconnect sensor application and each sensor RF tag data, we propose an information system architecture with which we can efficiently control and share the data obtained from sensors.
