Wireless communication method, wireless communication apparatus and wireless communication program
First Claim
1. A wireless communication method in a wireless communication system using a plurality of channels, comprising:
- the step of allowing each node in the wireless communication system to store channels available to a self node and a node adjacent to the self node in a channel status table; and
the step of allowing each node in the wireless communication system to select a channel to be used for transmission of a data packet based on the channel status table.

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.

10. A wireless communication apparatus that conducts wireless communication using a plurality of channels, comprising:
-
a channel status table in which a channel available to a self node and a primary adjacent node is stored, the primary adjacent node being a node adjacent to the self node; and a channel selecting unit that selects a channel available to the self node and the primary adjacent node as a channel to be used for transmission of a data packet to the primary adjacent node based on the channel status table. - View Dependent Claims (11)
