Abstract
A two-hop distant node is recognized by exchanging a Hello message, and an RTS message is transmitted through a doubled transmission distance prior to transmission of a data packet. Each node manages a channel available to a self node and an adjacent node in a channel status table based on the RTS message. A node which tries to transmit the data packet refers to the channel status table, so as to be capable of easily selecting a channel available to the self node and a node of a communication destination. Transmission wireless field strength is enhanced or a modulating system strongly resistant to noises is used so that the RTS message is transmitted at a distance which is not less than twice as long as that of the Hello message and the data packet.
