First Claim
1. A sensor value acquiring method executed by a computer that controls a plurality of mobile terminals to acquire a plurality of sensor values of a plurality of sensors included in the plurality of mobile terminals through a wireless communication link, the method comprising:
- acquiring, by the computer, a plurality of sensor values from the plurality of mobile terminals with which the wireless communication link is established, the plurality of sensor values being obtained by the plurality of sensors included in the plurality of mobile terminals;
storing, by the computer, each of the acquired sensor values along with an identifier to identify a mobile terminal with which each of the acquired sensor values was acquired;
comparing, by the computer, the stored sensor values corresponding to different identifiers;
extracting, by the computer, mobile terminals, as mobile terminals in a same condition, with which a difference of compared sensor values is equal to or smaller than a threshold value;
determining, by the computer, from the extracted mobile terminals, at least a first mobile terminal and at least a second mobile terminal, the at least first mobile terminal being controlled to transmit first sensor value with first time interval, the at least second mobile terminal being to be controlled to transmit second sensor value with second time interval which is longer than the first time interval; and
transmitting, by the computer, to the at least second mobile terminal an instruction to change the time interval of transmitting thesecond sensor value to the second time interval.

Abstract
A sensor value is obtained by a sensor included in a terminal from among a plurality of terminals each of which includes the sensor, the acquired sensor value is stored along with an identifier used to identify a terminal with which the acquired sensor value was acquired, identifiers are extracted with which a difference of corresponding stored sensor values is equal to or smaller than a threshold value by comparing stored sensor values corresponding to different identifiers, an instruction for acquiring the sensor value is transmitted to at least one of the terminals corresponding to the extracted identifiers, and an instruction for extending an interval of acquiring the sensor value is transmitted to the terminals which are other than the at least one of the terminals corresponding to the extracted identifiers.
