Trustworthy and Efficient Data Trading in Decentralized Mobile Crowd Sensing Systems
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.
