Abstract
A method and apparatus for channel assignment within an ad-hoc communication system utilizing multiple channels is provided herein. Individual nodes receive and send route-request (RREQ) packets on all channels rather than a single channel. Each route-request packet comprises a first and a second table. The first table comprises a channel state for the link and the second table comprises a channel quality metric for the link. Each node updates the channel state and channel quality tables and forwards them in the RREQ packet as part of the route-discovery process. When channel selection is made, the channel selection is based on the channel state and the channel quality tables.
