摘要
移动群智感知(mobile crowd sensing,MCS)系统提供了充分利用人群智慧的机会,具有部署成本低、空间覆盖范围广等优点。由于中央服务器可能存在的故障或风险问题,该研究以分散的方式构建具有不可信参与者的高效MCS系统。基于分布式拍卖过程和区块链系统,提出一种高效实用的去中心化MCS系统。该方法通过一个中立、公开和可信的平台,实现了满足个人理性和保护个人隐私的最优社会利益。理论分析和数值实验均证实该方法的有效性。
Mobile crowd sensing(MCS)systems,which offer a great opportunity to take full advantage of the wisdom of the crowd,naturally benefit from low deployment cost and wide spatial coverage.Due to failure or risk caused by a central server,constructing an efficient MCS system with untrustworthy participants in a decentralized manner is investigated.An efficient and practical decentralized MCS system based on a distributed auction process and the blockchain system is proposed.The proposed method achieves the optimal social profit satisfying individual rationality and protecting their privacy,through a neutral,public and trustful platform.Both theoretical analysis and numerical experiments show the effectiveness of the proposed approach.
