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.
