<P>PROBLEM TO BE SOLVED: To manage operation states of a plurality of nodes composing a communication system, and distinguish a trouble cause when any trouble occurs. <P>SOLUTION: In a node management system which manages the operation states of nodes with communication timing control means which autonomously decide data communication timing of the own node, the node management system of the invention is provided with: a neighborhood node information collection means which collects neighborhood node information regarding to neighborhood nodes of each node from each node; a node management information creation means which creates node management information which has at least receiving/not-receiving information of neighborhood node information which shows receiving/not-receiving of neighborhood node information from each node, node discrimination information of the transmission source node of neighborhood information, and neighborhood node discrimination information of neighborhood nodes of the transmission source node based on collection results of neighborhood node information by the neighborhood node collection means; and a node information management means which manages communication states of each node based on the node information. <P>COPYRIGHT: (C)2008,JPO&INPIT |
