基于区块链的城市智能交通网络均衡分配方法

Equilibrium Allocation Method of Urban Intelligent Transportation Network Based on Blockchain

为了提高城市智能交通网络的应用效率,有效分配网络中存在的资源,同时保证网络资源分配的均衡度。因此,提出区块链技术下城市智能交通网络均衡分配方法。通过建立城市智能交通网络模型,分析用户在交通网络中的资源需求。根据用户的需求,采用区块链技术分配网络中的资源,通过引入椭圆曲线数字签名算法,对需求和资源的发布信息加密处理,并根据资源需求与资源供应之间的匹配,完成城市智能交通网络资源的均衡分配。实验结果表明,所提方法的用户吞吐率高,且Jain公平指数在0.8以上,表明所提方法的资源分配合理性高。

In order to improve the application efficiency of urban intelligent transportation networks and effectively allocate the network resources while ensuring the balance of resource allocation,this article put forward a balanced allocation method for urban intelligent transportation networks based on blockchain technology.At first,we built a model of an urban intelligent transportation network to analyze the resource demand of users.On this basis,we allocated the resources in the network through blockchain technology.Moreover,we used the elliptic curve digital signature algorithm to encrypt and process the information on demand and resources.Finally,we completed the balanced allocation of urban intelligent transportation network resources according to the relation between resource demand and resource supply.The experimental results prove that the user throughput of the proposed method is high,and the Jain fairness index is more than O.8,indicating that the resource allocation rationality is higher.
