基于图着色理论的最大效用频谱分配算法
Maximum Utility Spectrum Allocation Algorithm Based on Graph Coloring Theory
摘要
Abstract
By the research of dynamic spectrum allocation algorithm based on graph coloring theory, this paper proposes an improved maximum utility spectrum allocation algorithm. It produces the matrix of the user, utility and interference with each other as Improved Spectrum Allocation Algorithm(ISSA), seeks the user who has the maximum utility or whose interference value is zero and allocates it homologous spectrum according to the matrix. Simulation results show that this algorithm can reduce the allocation period, the efficiency of spectrum is further improved, and it can expand the spectrum reusability in Cognitive Radio(CR) systems.关键词
