Abstract
Provided is a sensor node including: a sensor for measuring biological information; a CPU for acquiring data by driving the sensor; a wireless communication unit for transmitting the data acquired by the CPU; a battery for supplying the control unit, the wireless communication unit, and the sensor with electric power; a RAM for storing the data; a compression unit for compressing the data stored in the RAM when the wireless communication unit cannot carry out the transmission; and a flash memory for storing the compressed data, thereby storing as much sensing data as possible on the sensor node, which is limited in resources, and preventing loss of the sensing data.
