摘要

In a sensor network system wherein sensors are connected to a servers for generally managing them over a communication network, the server which manages the sensors acquires data on the residual drive time of the battery of each sensor, sets target residual drive times, and controls the operation of each sensor so that the residual time of the battery of each sensor may become equal to the target residual drive time. Thus, it is possible to alleviate the maintenance burden on the system manager, particularly battery charging of the sensors.
