Vehicle Computing Task Unloading Method Based on Blockchain Data Sharing

A vehicle computing task unloading method based on blockchain data sharing aims at data sharing and safe transmission of computing task unloading between vehicles, and designs a sharing transmission mechanism of computing unloading service vehicle information in edge computing nodes by using blockchain technology, which can ensure that trusted service vehicle information can be released in a large range and promote effective matching between user vehicles and service vehicles. To solve the problem of limited roadside resources for computing task unloading between vehicles and roadside edge nodes, the computing unloading behavior of each vehicle is regarded as competition for edge server resources. Game theory framework is used to describe the competitive behavior of each vehicle in the scene. The computing unloading strategy of each vehicle is determined according to the resource occupation of edge nodes and the situation of peripheral service vehicles, so as to achieve a balanced state among the computing unloading strategies of each vehicle, which can improve the operation efficiency of edge computing system on the premise of effective utilization of resources. -43 Start., icepoviingvehicles upload their owntsrice cpility ationtoroadideed computigncdes Roadside edp node: collect vehicle capabili ty inf aticn d u:se blochain technology to publi:h and shAre i ts upl1ink Pe-ce cxAabiity information in the blo- itwuedby vehides [the overall are of roadside edt ncdes The vehicle Inlye the peipheralser'ice vehicle information sent by the edr- ncde and de termines i ts own .pplicatonunloadingrequirement a ., Yesi!
