Next contribution is Routing Protocol.
RBMRP is designed by modifying the HWMP to suit for multi-channel and multi-radio environment.
So I modified Hello message and PREQ msg and PREP message.
The Hello message is delivered to the sending interface during the CCH period, but it contains the receiving channel information.
When a node transmits data to another node, it transmits the data after switching the sending interface channel to the destination node¡¯s receiving channel.
That information could be known through the Hello message.
And after routing, routing metrics are updated through Hello message.
And a PREQ message is broadcasted including two metrics for uplink routing and downlink routing in a CCH interval.
