摘要

PROBLEM TO BE SOLVED: To collect sensor data of high-precision (high-resolution) and to suppress congestion in a communication network and a processor for the sensor data, in a sensor network system.;SOLUTION: A sensor node 1 has a contribution calculation means 123 for calculating the effects of detected sensor information on the overall precision (resolution). Then, a first communication means 121 transmits the sensor information according to the calculated contribution so that congestion will not develop due to the transmission of a large amount of data, all at once.;COPYRIGHT: (C)2007,JPO&INPIT
