Vehicle computing resource allocation method in urban computing environment

Abstract

The invention discloses a vehicle computing resource allocation method in an urban computing environment, and relates to related technologies such as a block chain, a contract theory and a reputationmechanism. Firstly, a framework of an alliance block chain is introduced, decentralization of the system is achieved, and traceability and non-modifiability of distributed records are also achieved; meanwhile, the contract theory is applied to the system, so that the problem of information asymmetry between entities in the resource allocation process is solved; the two measures ensure the privacysecurity of the user to a great extent, the willingness of the user to participate in computing resource allocation is improved, and the system is automatically executed through a corresponding algorithm, so that tedious procedures in a third-party mechanism are omitted, and the resource allocation efficiency is greatly improved; besides, in the process of selecting the corresponding task unloading vehicle for the building calculation task, the high-reputation vehicle is screened out through a reputation mechanism, and it is guaranteed that high-quality service is provided for the building.

Description

technical field [0001] The invention relates to the technical fields of block chain and urban traffic, in particular to a vehicle computing resource allocation method in an urban computing environment. Background technique [0002] With the rapid development of information technology and the Internet, all kinds of mobile devices, home and commercial PC equipment, and a large number of sensors are connected to the Internet through various interfaces, which makes the demand for various data calculation, storage, and communication grow rapidly. Especially in various densely populated urban buildings, various devices have a great demand for computing. However, not all buildings have sufficient computing equipment. Such buildings as commercial office buildings do not have enough computing resources. The delay is large, and it cannot provide users with high real-time and reliable computing services. [0003] With the rapid development of the global economy, the number of cars in...

Problems solved by technology

[0004] The solution of using vehicles on the road to provide computing resources for buildings still faces many challenges: on the one hand, buildings and vehicles are unwilling to disclose their private information (such as: identity information, driving information, etc.) For other entities, the existing schemes all need to rely on authoritative third-party organizations to conduct computing resource transactions. Once the third-party organization fails or there is a person who maliciously steals information within the organization, the privacy of both parties involved in the transaction will be greatly threatened. It will seriously hit the enthusiasm of both parties to participate in the transaction. At the same time, the distribution through a third-party organization will also cause low efficiency; on the other hand, there is currently a lack of an effective incentive mechanism to stimulate vehicles to provide their own on-board computing resources.

As a provider of computing resources, cars consume their own computing resources and communication resources to provide computing services for various devices in the building. If the vehicles do not get the corresponding benefits, they will not participate in the allocation of computing resources; in addition, due to Different buildings have different computing requirements, and different vehicles have different computing resources, and the information between entities is asymmetric, lacking an effective task allocation mechanism
