Title:
SENSOR NETWORK SYSTEM AND COMMUNICATION PATH DETERMINING METHOD
Document Type and Number:
Japanese Patent JP2009253359
Kind Code:
A
Abstract:

To solve the problem wherein much time is required to determine a communication path, communication is interrupted during the determining time, and a target cannot be detected in some cases, because the communication path is autonomously determined and when a trouble occurs in the path, a new different communication path is autonomously determined in a network system according to a conventional technique.

A sensor network system is configured so that a plurality of communication paths from each of sensors to a management device are determined in advance and when an abnormality occurs in a communication path, a certain communication path is immediately switched to another communication path.
