CHAI Zheng-yi1, LIU Fang1. Spectrum allocation of cognitive wireless network based on immune clone selection optimization[J]. 2010, 31(11): 92-100.DOI:
The spectrum sensing process was described based on WRAN.By analyzing physical connection of cognitive wireless network
the mathematical model of spectrum allocation was given
and then it was converted into a constrained optimization problem
whose goal was to maximum the profit of network.An immune clone selection algorithm was proposed to solve the problem
and the algorithm convergent with probability 1 was proved.Finally
the simulation experiments were done to test the algorithm.The results showed that compared with CSGC algorithm(color-sensitive graph coloring) and GA-SA(spectrum allocation based on genetic algorithm)
this algorithm could achieve maximization of network profits.Meanwhile
the system simulation results based on WRAN confirmed its effectiveness.
