COMMUNICATION SYSTEM, CONTROL STATION THEREOF AND COMMUNICATION METHOD
First Claim
1. A communication system in which a plurality of control stations supervise respective ones of different networks and multiple nodes belonging to each network perform a data transmission, wherein each control station comprises:
- an acquisition unit which acquires the number of active paths for which the qualities of communication links between the nodes belonging to the supervised network exceed a prescribed threshold value; and
a moving unit which, in case of existence of a node for which the number of active paths that exceeds the prescribed threshold value is smaller than a prescribed number, moves the node between the network in which the node exists and another network.

Abstract
A plurality of control stations supervise respective ones of different networks and multiple nodes belonging to each network perform redundant transmission of data. The number of communication paths for which the qualities of communication links between the nodes belonging to the network are greater than a threshold value are calculated as the number of active paths of each of the nodes belonging to each network, and it is determined whether the calculated number of active paths of each node in each network is equal to or greater than a predetermined redundancy. In case of existence of a node for which the number of active paths is less than the predetermined redundancy, then the node is moved between the network in which the node exists and another network.
