Directional, Fast New Method for Channel Allocation. The average number of iterations, the average degree of interference and the relationship between the convergence time and the number of PSO and the number of channels are simulated and analyzed. Experimental results show that this method has the advantages of fast convergence rate and small conflict degree, and guarantees the fastness and accuracy of channel allocation in wireless UV networks.
