双向拍卖结合贝叶斯模型的认知无线电网络频谱共享方案
Cognitive radio network spectrum sharing scheme for double auction combining Bayesian model
摘要
Abstract
Since the spectrum resource in radio networks is limited and its utilization is low,a spectrum sharing algorithm for double auction combining Bayesian inference model is proposed. Firstly,the primary users and the secondary users adaptive⁃ly select their auction prices to share the spectrum bands. And then,based on feedback learning process,the players capture their adjustable price strategies. Finally,the auction process is repeated until the consensus is reached. The algorithm adopts Bayesian inference technique,which can adaptively response to the constantly changing system environment and players′ quanti⁃ty. It has better scalability. The simulation results show that the proposed algorithm is superior to several other advanced spec⁃trum sharing algorithms in the aspects of PU benefit,trade success rate,spectrum efficiency and network throughput.关键词
