Abstract

In a distributed information communication processing system in which a plurality of information communication devices provides a service through a network, response speed, electric power consumption, and further reliability are improved. The distributed information communication processing system which provides various services is configured by associating an entrance node (EN) which executes filtering near sensors, actuators, and terminals being information sources, an intelligent node (IN) which changes an information processing position and executes information processing and communication processing instead of a data center (DC), and a management node (MN) which manages these nodes. Thereby, real time type information processing can be realized.
