摘要
随着无线电业务的爆炸式增长,频谱稀缺成为无线通信中一个棘手的问题。在此背景下,认知无线电网络应运而生,而选择最佳的信道进行频谱切换是认知无线电网络面临的一个挑战。目前,利用博弈论选择最佳信道进行频谱切换被证明是有效的方法。研究了一种基于双边拍卖机制的认知无线网络频谱切换优化方案,提出了一种基于传输率的报价算法。仿真结果表明,利用该方案选择最佳信道进行频谱切换十分有效。
With the explosive growth of radio services,the scarcity of spectrum has become a thorny issue in wireless communication.In this context,cognitive radio networks came into being,and choosing the best channel for spectrum switching is a challenge for cognitive radio networks.At present,it is proved to be an effective method to select the best channel for spectrum switching by game theory.An optimization scheme of spectrum switching in cognitive wireless networks based on bilateral auction mechanism is studied,and a quotation algorithm based on transmission rate is proposed.The simulation results show that it is very effective to select the best channel for spectrum switching by using this scheme.
