Claim:
1. A node device comprising: a communication unit configured to transmit a data frame containing frequency information which indicates a number of times that the data frame is transmitted, and receive the data frame transmitted from any one of a plurality of adjacent node devices; a storage unit configured to store a table in which frame identification information for identifying the data frame and the frequency information of the data frame are associated with each other; and a control unit configured to: determine whether a destination of the received data frame is its own node device; determine, when it is determined that the destination of the received data frame is not its own node device, whether the frame identification information of the received data frame is registered in the table; determine, when it is determined that the frame identification information of the received data frame is registered in the table, whether the number of transmission times indicated by the frequency information of the received data frame is less than or equal to the number of transmission times indicated by the frequency information corresponding to the frame identification information registered in the table; update, when it is determined that the number of transmission times indicated by the frequency information of the received data frame is greater than the number of transmission times indicated by the frequency information corresponding to the frame identification information registered in the table, the frequency information corresponding to the frame identification information registered in the table with the frequency information of the received data frame; and increase, when it is determined that the number of transmission times indicated by the frequency information of the received data frame is greater than the number of transmission times indicated by the frequency information corresponding to the frame identification information registered in the table, the number of transmission times indicated by the frequency information of the received data frame, wherein the communication unit transmits the data frame for which the number of transmission times is increased to an adjacent node device which is not selected as a transmission destination of the data frame.
