COMMUNICATION APPARATUS, COMMUNICATION SYSTEM, COMMUNICATION METHOD AND COMMUNICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a communication apparatus capable of specifying a moving group with less control load when a group of nodes is optionally formed or changed.SOLUTION: Upon detecting a disconnected node as an adjacent node having a link disconnected from the own node, a searching control message-transmitting unit 71 transmits a searching control message for searching a destination node and including information for specifying a node belonging to the moving group, for each destination node using the disconnected node as a node on a path. Upon receiving the searching control message from another communication apparatus, an information extracting unit 72 extracts information for specifying a node belonging to the moving group from the received searching control message. A moving node-specifying unit 74 specifies the node belonging to the moving group on the basis of the information extracted by the information extracting unit 72.
