1. A method for a node to aide in channel assignment within an ad-hoc communication system, the method comprising the steps of:
receiving a route-request (RREQ) packet on a first frequency, the RREQ packet comprising information;
determining if the node is acting as an intersection between two active flows and is switching between two channels to support the flows;
determining a channel quality taken from the group consisting of an interference metric, an achievable throughput, a congestion, and a channel load;
updating the information based on if the node is acting as an intersection between two active flows and is switching between two channels to support the flows, and additionally updating the information based on the channel quality;
transmitting the RREQ packet having the updated information to all neighboring nodes, wherein the transmission takes place on all available frequencies and is utilized for channel assignment.
