面向非可信节点的联合频谱感知与资源分配机制设计OA

To address the issues in spectrum sharing systems,such as unreliable sensing results because of the data falsifica-tion and unfair access allocation,a spectrum sharing model based on the sensing quality was proposed.By jointly optimizing sensing quality and access resource allocation,this model improved efficiency and fairness.In the sensing phase,a leader-follower game modeled the interaction between sensing users and demanders:the sensing users optimized sensing quality to maximize their benefits,while the demanders determined data purchases based on sensing quality,ensuring efficient and reli-able data collection.In the access phase,spectrum resources were dynamically allocated based on the sensing quality,with the VCG(Vickrey-Clarke-Groves)mechanism ensuring truthful reporting and preventing data falsification and fraud.This led to fair and optimized spectrum allocation,enhancing the overall system efficiency.Simulation results show that the pro-posed mechanism effectively incentivizes users to report the true sensing quality and protects the honest users.
