LOW-POWER CONSUMPTION WIRELESS SENSOR TERMINAL AND SENSOR NETWORK SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide individual identification technique of a low-power consumption type wireless sensor terminal in a sensor network system suitable for observation, or the like, of a living body individual group. PSOLUTION: The sensor network system includes a plurality of wireless sensor terminals, and at least one reception device. Each of the plurality of wireless sensor terminals transmits a frame of the same telegram length as each other, and transmits the frame at a baud rate and/or a frequency different from each other; the reception device has a storage part capable of storing association information for associating a specified individual of the plurality of wireless sensor terminals to a specified baud rate and/or frequency, and performs individual identification of the wireless sensor terminal, based on the association information stored in the storage part and the baud rate and/or the frequency of a reception signal.
