在频谱共享系统中，为了保护主用户和从用户不受干扰，定义了一个隔离区。减小隔离区的大小是有效利用休耕频谱的关键。本文提出了一种新的众包增强隔离区优化框架。在我们的框架中，采用一种使用频谱访问权的易货交换模型来激励二级用户（su）参与众包。我们进一步设计了一种真实拍卖机制，以计算效率的方式选择SUs并确定其访问时间。我们进行了仿真来验证所提出的机制，并将其与两个基线方案进行了比较。
In spectrum sharing system, an exclusion zone is defined to protect both primary and secondary users from interference. Reducing the size of exclusion zone is critical for efficiently utilizing the fallow spectrum. In this paper, we propose a novel crowdsourcing augmented exclusion zone refinement framework. In our framework, a barter-like exchange model using spectrum access right is employed to incentivize the secondary users (SUs) to participate in the crowdsourcing. We further design a truthful auction mechanism to select the SUs and determine their access time in a computationally efficient way. We perform simulations to validate the proposed mechanism, and compare it with two baseline schemes.
