Wireless communication device, wireless communication method and a wireless communication program

To prevent a decrease in power consumption deterioration and the communication speed of the wireless communication. Each node 50, the number of nodes to be searched to determine the transmission power for data communication so that the target value, and stores the node address of the node to be searched at that transmit power to the adjacent node address storage section 25. Further, to determine the transmission power for the same control communication. If the node 50 transmits a data frame to another node, and transmits the ERTS frame including a node address stored in the adjacent node address storage unit 25 by the transmission power for control communication, after receiving the ECTS frame, for data communication transmitting the data frames in the transmit power. Control information input and output unit 24 determines a node in the NAV period from the received ERTS frame or the like, and stores the node address of the node to NAV set node address storage section 26.
