非合作认知无线电网络中,多个主用户和多个第2用户并存.主用户和第2用户是自私的和理性的,主用户和第2用户都希望在不影响他人收益的前提下获得自己的最大收益.这符合连续双向拍卖市场对用户的假设条件.针对这一特点,基于实验经济学理论,提出了基于模糊逻辑连续双向拍卖的动态频谱分配策略.在频谱拍卖过程中,主用户和第2用户均采用基于模糊逻辑的报价策略.采用该方法,主用户和第2用户可以根据交易情况实时调整自己的报价步长,减少报价次数,迅速完成交易.仿真结果表明该方法的频谱分配效率为85%,较好地解决了非合作认知网络中多对多环境下的动态频谱分配问题.
非閤作認知無線電網絡中,多箇主用戶和多箇第2用戶併存.主用戶和第2用戶是自私的和理性的,主用戶和第2用戶都希望在不影響他人收益的前提下穫得自己的最大收益.這符閤連續雙嚮拍賣市場對用戶的假設條件.針對這一特點,基于實驗經濟學理論,提齣瞭基于模糊邏輯連續雙嚮拍賣的動態頻譜分配策略.在頻譜拍賣過程中,主用戶和第2用戶均採用基于模糊邏輯的報價策略.採用該方法,主用戶和第2用戶可以根據交易情況實時調整自己的報價步長,減少報價次數,迅速完成交易.倣真結果錶明該方法的頻譜分配效率為85%,較好地解決瞭非閤作認知網絡中多對多環境下的動態頻譜分配問題.

Multiple primary and multiple secondary users coexist in non-cooperation cognitive networks.All primary and secondary users are selfish and rational with the hope of acquiring the maximum gain on condition that they do not harm the profits of others,which accords with the hypothesis of users in continuous double auctions.For this characteristic, dynamic spectrum allocation based on fuzzy-logic continuous double auctions is proposed,based on the theory of experimental economics.In spectrum auctions,every user uses bidding strategy based on the fuzzy-logic.With this method,they can adj ust their bidding steps in time according to the business situation,and reduce the time of bid to finish the business rapidly.Simulation results show that our proposed scheme has 85%efficiency of spectrum usage.Dynamic Spectrum allocation in the multi-to-multi situation in non-cooperation cognitive networks is solved effectively with the method proposed in the paper.
