1. A data collection method of a system that transmits and receives data by respective communications apparatuses among a plurality of communications apparatuses performing multihop communication, the data collection method comprising
suspending transmission of data obtained from a second sensor, a communications apparatus among the plurality of communications apparatuses suspending the transmission by the second communications apparatus when a difference between data obtained from a first sensor of a first communications apparatus among the plurality of communications apparatuses and data obtained from the second sensor of a second communications apparatus among the plurality of communications apparatuses is within a threshold;
resuming the transmission of the data obtained from the second sensor, the communications apparatus among the plurality of communications apparatuses resuming the transmission by the second communications apparatus when, after the transmission of the data obtained from the second sensor has been suspended, the difference between the data obtained from the first sensor and the data obtained from the second sensor exceeds the threshold;
setting the first communications apparatus and the second communications apparatus to be in a same group, the communications apparatus among the plurality of communications apparatuses setting the first communications apparatus and the second communications apparatus to be in the same group when the difference between the data obtained from the first sensor and the data obtained by the second sensor is within the threshold; and
transmitting the data obtained from the first sensor and identification information indicating that the first and the second communications apparatuses are in the same group, the first communications apparatus transmitting the data and the identification information when the communications apparatus among the plurality of communications apparatuses sets the first communications apparatus and the second communications apparatus to be in the same group.
