Abstract

Cognitive radio is a promising paradigm to improve utilization of the radio frequency spectrum. In this work, we study a contract-based mechanism for sharing spectrum among primary licensed user (PU) and secondary unlicensed users (SUs). We assume that SUs cooperate in PU signal transmission. However, there are some challenges that the PU should overcome. First, considering the fact that nodes are selfish, brings the necessity of a reimbursement method to remunerate the helping SUs. Second, SU hides its private channel state information from other nodes, which results in asymmetry of information. The proposed contract-theory based framework provides a solution for spectrum allocation under asymmetric channel information. We compare the performance results with a benchmark scenario and we show through simulation results that both the PU and the SU gain positive revenue.

认知无线电网络中基于契约的合作频谱共享
认知无线电是一个很有前途的范例,可以提高无线电频谱的利用率。在这项工作中,我们研究了一种在主许可用户(PU)和辅助未许可用户(SUs)之间共享频谱的基于契约的机制。我们假设su协同PU信号传输。然而,人民党需要克服一些挑战。首先,考虑到节点是自私的,需要一种补偿方法来补偿帮助节点的su。其次,SU对其他节点隐藏其私有通道状态信息,导致信息不对称。提出的基于契约理论的框架为信道信息不对称情况下的频谱分配提供了解决方案。我们将性能结果与基准场景进行比较,并通过模拟结果表明,PU和SU都获得了正收益。
