WIRELESS COMMUNICATION METHOD, WIRELESS COMMUNICATION DEVICE, AND WIRELESS COMMUNICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a wireless communication technology for efficiently achieving multi-casting communication of high reliability.

SOLUTION: The wireless communication method is that a destination node which has been able to receive a multi-casting packet retransmits the packet to a destination node which has not been able to receive the packet. It includes: a step that the destination node which receives the multi-casting packet transmits a reception report (ACK); a step that a node which receives the reception report transmits a non-reception report (NACK) when the node does not receive the packet corresponding to the reception report; and a step that a destination node which receives the non-reception report, transmits the packet requested retransmission. It is desirable that the node which receives the non-reception report retransmits the packet reported as a non-reception packet after a predetermined period elapses from reception of the non-reception report. Further it is desirable that the own node stops retransmission when another node performs retransmission of the packet during the interval.
