Embodiment Construction

[0088] The specific real-time manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0089] The vehicle computing task unloading method based on block chain data sharing in the present invention, such as figure 1 As shown, it is realized through the following steps:

[0090] Step 1. The service providing vehicle uploads its own service capability information to the roadside edge computing node;

[0091] A. At the edge node MEC m Within the range of roads covered by the network, the intelligent vehicle j with redundant computing resources that intends to provide computing task offloading services determines its own computing capability resource that can provide services j , the time period during which the service can be provided j , The planned trajectory of the vehicle during this period of time trajectory j and the car's initial pricing for its services init_price j ;

[0092] B. Establishment of vehicle i and e...

Abstract

The invention discloses a vehicle computing task unloading method based on blockchain data sharing. Aiming at solving the problems of data sharing and secure transmission of computing task unloading between vehicles, a shared transmission mechanism of computing unloading service vehicle information in an edge computing node is designed by utilizing a blockchain technology, trusted service vehicleinformation can be published in a large range, and effective matching between a user vehicle and a service vehicle is promoted. Aiming at the problem of limited roadside resources of calculation taskunloading between vehicles and roadside edge nodes, the calculation unloading behaviors of the vehicles are regarded as competition for edge server resources, and game theory description is carried out on the competition behaviors of the vehicles in a scene by utilizing a game theory framework, the calculation unloading strategy of each vehicle is determined according to the resource occupation situation of the edge node and the surrounding service vehicle situation, the balance state between the calculation unloading strategies of each vehicle is realized, and the operation efficiency of theedge calculation system can be improved on the premise of effective utilization of resources.

Description

technical field [0001] The patent of the present invention relates to vehicle computing task offloading technology in the intersecting field of intelligent transportation system, edge computing technology and blockchain technology, and in particular to a vehicle computing task offloading method based on blockchain information sharing in edge computing network connection. Background technique [0002] With the continuous development of intelligent transportation systems and autonomous driving technologies, more and more in-vehicle applications have emerged, covering all aspects of driving safety, traffic efficiency, and infotainment. A large number of computing-intensive and latency-sensitive applications make the vehicle's requirements for computing and storage capabilities continuously increase, and each vehicle is limited by physical space and economic costs, and the local resources it provides cannot fully meet the needs of these applications. [0003] In order to solve t...
