A computing power trading method based on device reliability and mobility
In order to solve the problems of low utility,low credibility,and poor security in the process of computing power resource trading,a social welfare maximization model is established considering the impact of device credibility and device mobility on device computing costs.In the satisfaction maximization model,the value of the data is regarded as the measurement criteria.Then,the computing resources auction scheme between computing power requesters and potential sellers is solved by the greedy algorithm.The bidding process between multi-sellers and multi-buyers is improved by the auction game and the clipping algorithm.Finally,the decentralized,transparent,and tamper proof blockchain technology is employed,and a smart contract mechanism is developed to manage and supervise the auction process.The results indicate that the proposed model further ensures the authenticity of transactions on the basis of existing mechanisms,improves the utility of computing resource transactions to a certain extent,and effectively improves the credibility and security of the transaction process.
