Research On Fair Auction And Trade Framework Of Network Resources Based On Blockchain

In recent years,with the popularity of cloud computing,cloud auction models that can allocate and price cloud resources have gradually received widespread attention.At the same time,as the processing power of mobile devices has been greatly improved,mobile crowdsensing technology that collects a large amount of perception data at low cost has developed rapidly,and the mobile crowdsensing incentive mechanism for task allocation and pricing has gradually attracted widespread attention.However,the trusted central auctioneer in the traditional cloud auction model and mobile crowdsensing incentive mechanism often does not exist,which makes it difficult to guarantee the fairness of the auction.At the same time,the traditional cloud auction scheme and mobile crowdsensing incentive mechanism only consider the auction strategy,and there is not much research on the subsequent trade process and how to ensure the fairness of the transaction.In view of the above problems,the introduction of blockchain technology has solved the problems of auction fairness and transaction fairness in cloud auction and mobile crowdsensing.The main work includes the following two aspects:(1)A fair auction trading framework for cloud resource allocation based on blockchain is proposed.Firstly,the fairness of the combinatorial auction model in cloud auction is realized by introducing the time commitment mechanism.Secondly,considering that it is difficult to verify the effectiveness of cloud services in the trade process,a trade model with a third party is proposed to ensure the fairness of the trade.In order to further realize the decentralization of the framework,a ladder payment method is proposed,and a trade model without a third party is proposed in combination with ladder payment,which ensures the fairness of the trade.The fairness analysis proves that the scheme meets the fairness requirements.Finally,the scheme is implemented in the simulation network and test network of Ethereum,and the experimental results prove the feasibility of the scheme.(2)A fair trading framework based on the blockchain-based mobile crowd sensing incentive mechanism is proposed.Considering the possible malicious behavior of the third-party platform in the traditional mobile crowdsensing model,this thesis proposes a decentralized mobile crowdsensing platform based on blockchain,and realizes the fairness of the reverse auction model in mobile crowdsensing incentive mechanism.Then,according to the characteristics that the incentive mechanism of mobile crowdsensing can effectively distinguish the quality of data submitted by different workers,this thesis proposes a mobile crowdsensing fair trade scheme without a third party,and proposes different data submission schemes for different types of sensing data.Then the fairness of the scheme is analyzed,which proves that the scheme meets the fairness requirements.Finally,the scheme is implemented in the simulation network and test network of Ethereum.The experimental results show that the scheme is feasible.
