| 摘 要： | 分析了认知无线电中基于拍卖的频谱分配的特点,给出了认知无线电系统中的频谱拍卖模型,并讨论了第一价格和第二价格密封拍卖机制在认知无线电频谱分配上的应用,研究了认知无线电中频谱拍卖问题的最优价格、保留底价等问题。最后还给出了简单情形下的仿真,结果表明,基于拍卖的频谱分配在吞吐量和丢包率等性能上较随机分配方案有明显改善。

| Abstract: | This paper analyzes the features of auction-based spectrum allocation in cognitive radio,gives a spectrum auction model for cognitive radio,discusses the applications of the first-price and second-price sealed-bid auction mechanism for spectrum allocation in cognitive radio,studies the issues of optimal price and reserved price in the auction process,and finally describes a simple simulation.The simulation result shows that the auction-based spectrum allocation is obviously superior to random distribution scheme in the throughput performances and packet loss rate. |
