Method and apparatus for channel assignment within ad-hoc communication system

A method for channel assignment, the method comprising the steps of:

• receiving a route-request (RREQ) packet on a first frequency, the RREQ packet comprising a first and a second table of information;
• determining a channel state for a plurality of channels;
• determining a channel quality for the plurality of channels;
• updating the first table based on the channel state;
• updating the second table based on the channel quality;
• determining a best channel for transmission based on the first and the second tables;
• and
• transmitting a route-reply (RREP) packet comprising the best channel.

A node comprising:

• a receiver having a route-request (RREQ) packet as an input on a first frequency, the RREQ packet comprising a first and a second table of information;
• logic circuitry determining a channel state for a plurality of channels, determining a channel quality for the plurality of channels, updating the first table based on the channel state, and updating the second table based on the channel quality;
• and
• a transmitter transmitting the RREQ packet having the updated first and second tables to all neighboring nodes, wherein the transmission takes place on all available frequencies and is utilized for channel assignment.
