Abstract: A node device includes: a communication unit to transmit a data frame containing frequency information and receive the data frame; a storage unit to store a table in which frame identification information and the frequency information are associated; and a control unit to: determine whether a destination of the received data frame is its own node device; determine whether the frame identification information of the received data frame is registered in the table; determine whether the number of transmission times is less than or equal to the number of transmission times corresponding to the frame identification information registered in the table; update the frequency information corresponding to the frame identification information registered in the table with the frequency information of the received data frame; and increase the number of transmission times, wherein the communication unit transmits the data frame for which the number of transmission times is increased.

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.

Abstract: A node equipment includes a receiver, a processor, a memory and a transmitter. The node equipment is relayed by a plurality of relay devices with a server. The receiver receives a frame from adjacent node equipment. The processor generates a wait number by incrementing a number of hops for each of the relay devices, when the number of hops to the adjacent node equipment is reported with a synchronization request, the number of hops being generated by designating each of the plurality of relay devices as a starting point. The memory stores the wait number in association with an identifier of the relay device. The transmitter transmits a data frame in which the server is designated as an address. The processor outputs to the transmitter a data frame in which a relay device having a relatively small wait number stored in the memory is designated as a relay destination.
