PROBLEM TO BE SOLVED: To reduce the number of exchanges of route information between route control devices in comparison with conventional arts.SOLUTION: A node 10 which relays a data packet transmitted from a node 10 comprises: a transmission destination determination unit 152 for determining, as a transmission destination of a data packet, a node with the minimum number of attempts set for each of nodes that can be transmission destination candidates in route control information set for each destination in a routing table; a table update unit 153 for setting and registering the route control information in the routing table by referring to relay node information which is included in the data packet and to which the node that has relayed the data packet is set; and a packet update unit 154 for adding information on the node 10 itself to the relay node information included in the data packet. The table update part 153 adds one to the number of times of attempts corresponding to the transmission destination of a data packet after transmission of the data packet. |
