基于频谱异质的多单元双向频谱拍卖算法

针对频谱资源的异质性,提出一种基于频谱异质的多单元双向频谱拍卖算法.利用双边频谱拍卖模型,从多单元拍卖和异质频谱拍卖2个方面对算法进行改进,允许买家竞买、卖家提供多个不同中心频率的异质信道,实现互不干扰买家间频谱复用.分析证明了该算法满足拍卖机制设计的3个经济学性能:个体理性、收益均衡和真实性.仿真实验结果表明,该算法在频谱拍卖效率和系统收益方面皆有良好表现.

A Multi-channel Double Auction Algorithm Based on Spectrum Heterogeneity

In view of the heterogeneity of spectrum, propose a multi-channel double auction algorithm based on spectrums heterogeneous. Using double auction model, improved the algorithm from two aspects: multi-channel auction and heterogeneous spectrum auction. It allows buyers/sellers to request/provide multiple channels with different center frequencies, consider non-identical conflict relationship to explore spectrum reusability. We prove that the algorithm satisfied the economics properties: truthfulness, individual rationality and budget balance. And the simulation results confirm that our algorithm achieves high auction efficiency and system revenue.
