Title:
センサネットワークシステム、センサノード、センサ情報収集装置、事象観測方法、およびプログラム
Document Type and Number:
Japanese Patent JP4787578
Kind Code:
B2
Abstract:
In a sensor network system, sensor data having a high precision (high resolution) is collected, and congestion of a communication network and an apparatus for processing the sensor data is suppressed. A sensor node has a contribution degree calculator for calculating an influence that the detected sensor information exerts upon the entire system precision (resolution). A first communicating circuit transmits sensor information responding to a calculated contribution so that no congestion caused by transmitting too large a quantity of data all at once occurs.
