In the route selection process, we focus on selecting the best route, which has the assigned channel obtained from the channel allocation process, for each data frame transmission to optimize the multihop cognitive radio network performance.

However, recent studies showed how scarcity is almost due to the static spectrum allocation strategies and that cognitive radio can be the way to improve the spectrum usage.
In order to discuss cognitive radio networks, we redefine CR as: "Wireless communication system that intelligently utilizes any side information about activity, channel conditions, codebooks or messages of other nodes with which it shares spectrum."[5] An idea of making a CR based system or a CR network based on above definition of CR has caused much enthusiasm in several companies including the FCC.
