Abstract A parallel allocation algorithm is proposed, which is a modification of CSGC (Color Sensitive Graph Coloring)algorithm. Under constraint of maximizing system utilization, the parallel algorithm obtains the same allocation matrix as CSGC, while reducing the allocation period, so that it can be adapted to the agile sense requirement of cognitive radio. Results of simulation and analysis prove this conclusion.
