METHOD FOR SENSING SPECTRUM AND ALLOCATING CHANNEL USING GENE ALGORITHM IN THE COGNITIVE RADIO NETWORK

摘要

A method for efficiently frequency sensing and allocating channels using a genetic algorithm in a cognitive radio network is disclosed. A method for frequency sensing and channel allocation in a cognitive radio network including a virtual cluster head and a plurality of member nodes participating in a secondary user, the method comprising: performing broadband sensing on member nodes participating in the cognitive radio network Collecting channel information and traffic information corresponding to each of a plurality of member nodes, generating a hopping channel list including a usable common channel based on the channel information, Determining member nodes for sensing and member nodes for sensing based on the traffic information and the genetic algorithm for each of the plurality of member nodes at each hopping time, During the hopping time, the member nodes for the determined sensing The sensing for the next hopping channel is performed, and data transmission through the member node for the data transmission can be performed.
