PROBLEM TO BE SOLVED: To realize a communication system capable of reducing a communication amount on a wireless network not only during the occurrence of a fault but also during normal operation. SOLUTION: Each wireless sensor node 200 executes measurement by a sensor for every unit time and stores a measurement value. When the time elapses as calculated by multiplying to a unit time a maximum repeating frequency of the wireless communication system belonging to each wireless sensor node; each wireless sensor node 200 generates a data packet indicating the measurement value equivalent to an amount of the maximum repeating frequency, transmits the generated data packet, successively transfers it among the wireless sensor nodes in a bucket brigade format, and makes the data packet to reach a wireless server node 100.
