Study of Cooperative Algorithm Based on Multi-objective Function in Cognitive Radio
【摘要】 提出一种基于公平性最佳的优化算法(MPF),并且结合带宽收益最佳算法(MSB),给出一种新的协作算法。算法采用性能因子方法,构建出一种多目标函数准则,兼顾公平性与带宽收益,实现快速频谱分配。仿真结果表明,新的协作算法有效地保证了系统的带宽收益和公平性。
【Abstract】 In this article the Max-Proportional-Fair algorithm is proposed.Combined with Max-Sum-Bandwidth algorithm a new cooperative algorithm is proposed.The algorithm use performance factor to build a Multi-objective function rule with consideration to both fairness and bandwidth to achieve rapid distribution.The simulation results show the new algorithm makes two different objective functions of the network optimal.
