Based on the above discussion, to identify radio routing algorithm and protocol of the study is very necessary, the routing problem in this paper is aimed at identifying the user, due to its spectrum is discrete, identify the network routing design in addition to the problems, such as to consider the hop to consider spectrum characteristics and stability of the link. This paper applies genetic algorithm into the routing selection, then to improve the on-demand routing protocols make it suitable for identification of radio network and routing strategy of this paper, based on more network topology information, selected the existence of high performance routing.
