Abstract

An operation flow of each node is dynamically changed according to a user request or a situation. A client ( 205 ) includes: a step ( 415 ) of extracting a script for a lower node from scripts in which processing is preset for a plurality of nodes to distribute the script extracted to the lower node; a step of executing processing for a self node from the script; a step of causing the lower node to receive the script distributed to execute processing for the node; and a step 410 of causing the lower node to extract a script for a node lower than the self node from the scripts, and to distribute the extracted script to the lower node if the script for the lower node is present. Based on a script executed by each node, an event from a lowest sensor node is sent through an intermediate node to the client 205.

Description

technical field

[0001] The present invention relates to a technique for utilizing information from multiple sensors connected to the network, and in particular, involves collecting information from multiple sensors scattered in a region, and using it for status determination, abnormal discovery, prediction, optimization, etc. Supported sensor network systems. Background technique

[0002] In recent years, sensor network technologies for obtaining sensory data obtained from a plurality of sensor nodes through a network have been developed. The sensor network uses the information obtained by the sensor for remote use through the network, and must correspond to wide-area and various environmental observations. In the case of performing various observations over a wide area, a large number of various sensor nodes are required. If the server receives observation events (notifications of measurement results) of all these sensor nodes as they are, load concentration occurs on the...
