<p>PROBLEM TO BE SOLVED: To provide a node for a multi-hop network.SOLUTION: A transferred or monitored data packet is decoded. A source node, a destination node, a transmission node, a reception node, a type, and a data payload are acquired. When the number of hops from the source node to the destination node is larger than the number of hops from said node to the destination node and a difference between the two is 2, determination is made, on the basis of a data packet transfer table, as to whether or not a data packet was transferred or monitored. When the data packet was not transferred or monitored and the reception node is said node, information about a parent node of the source node is added to the data packet, and the data packet including the parent node information is transferred. When the data packet was not transferred or monitored, an information item corresponding to the source node and its parent node is stored in the data packet transfer table, a transmission mark is set to a prescribed value, and a forgotten time is initialized.</p> |
