Abstract: A node apparatus includes a receiving unit receiving a data frame from one of adjacent nodes apparatuses; a storing unit storing an identification information management table in which frame identification information with which the data frame may be uniquely identified, and overlapped data identification information; a processor which performs a process including: judging whether or not a final destination of the received data frame is the node apparatus itself; judging whether or not a registration that matches the frame identification information of the received data frame exists in the identification information management table; judging whether or not the overlapped data identification information of the received data frame and the overlapped data identification information corresponding to the registration match; and discarding the received data frame; and performing a retransmission of the received data frame to another adjacent node that has not been a transmission destination of the data frame.
