Abstract
Aimed at the problem that the color sensitive graph coloring algorithm of spectrum allocation holds true generally for a static network, this paper proposes a modified dynamic spectrum allocation strategy on the rule of maximization overall gains, based on dealing with the graph theory model of spectrum allocation and its allocation principles of coloring spectrum by color sensitive graph theory, and analyzes comparatively the performances on the previous algorithm and the new one by simulation. Simulation results show that the modified algorithm could reduce the overall benefit of cognitive network a bit, but lower greatly the expense of time and improve the timeliness of systems.关键词
