ABSTRACT:
A message sending device sends a message. A message receiving device generates reception authentication information of the message when receiving the message, and further generates reception confirmation information of the message by using the reception authentication information of the message, to send the reception confirmation information of the message to a reception confirmation information verification device. The reception confirmation information verification device verifies the received reception confirmation information. The message sending device obtains a reception confirmation of the message for the message receiving device based on the verification result. This configuration reduces a processing load in each node as much as possible for confirming whether data to large numbers of nodes under a multihop environment have been received in each node.
