Parallel Algorithm of Spectrum Allocation in Cognitive Radio
-
摘要: 该文通过对基于图论着色原理的开放式频谱分配算法的分析，提出了一种并行分配算法。在最大化系统效益的准则下，并行算法可以得到与CSGC (Color Sensitive Graph Coloring)算法相同的分配矩阵，但是却可以缩短分配周期，从而适应了认知无线电对环境的快速感知的要求。仿真结果分析验证了结论的正确性。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.
