1. A sensor network system, comprising:
- a plurality of sensor nodes each including a sensor for detecting an event that has occurred, and a communicating means for transmitting sensor information indicating the event detected by said sensor at a timing corresponding to an influence that the event detected by said sensor exerts upon a sensor information distribution indicating a temporal distribution and a spatial distribution of said event; and
an application apparatus for employing said sensor information distribution, thereby to process said sensor information.

Abstract
In a sensor network system, sensor data having a high precision (high resolution) is collected, and yet congestion of a communication network and an apparatus for processing the sensor data is suppressed.
A sensor node 1 has a contribution degree calculating means 123 for calculating an influence that the detected sensor information exerts upon the entire precision (resolution). And, a first communicating means 121 transmits sensor information responding to a calculated contribution so that no congestion caused by transmitting a large quantity of data all at once occurs.
