基于区块链和边缘计算的共享单车系统模型研究
首发时间:2018-05-23
摘要:目前流行的共享单车系统都依赖云服务器提供数据计算和处理,既容易造成中心服务器压力过大,数据库也可能受到单点破坏的危险。为减缓云服务器端对共享单车用户实时请求的处理压力,并对用户用车行为数据进行安全有效监管,规范用户用车停车。本文提出一种基于边缘计算和区块链的共享单车系统。结合用户使用的共享单车应用,把用户用车数据放在边缘端的节点服务器中分析与处理,如计时,计费,奖励等,同时将数据和处理结果记录在节点服务器上的区块链中 - 一个不可篡改,按时间戳记录,可追溯的分布式链式数据库,只将必要的结果传送到云端服务器。不仅加快对用户的实时响应,还能保证对用户用车信息的安全存储。实验分析了本文设想的可行性与边缘端数据分析处理的可靠性。

Research on Bicycle-sharing System Module Based on Blockchain and Edge-computing
Abstract:The current popular shared bicycle systems rely on cloud servers to provide data calculation and processing,which easily causes excessive pressure on the central servers and risks damaging data through the servers.In order to alleviate the cloud servers\' pressure of processing real-time requests,supervise users\' cycling data and standardize riding and parking.This paper proposes a bicycle-sharing system based on blockchain and edge-computing.Combined with the current bicycle-sharing application,our system analyzes and processes vehicling data by servers on the edge,such as timing, billing, rewarding data,meanwhile records the data in the blockchain,which is a non-disruptive,time-stamped,traceable,distributed,chained database.Then it delivers only the necessary results to the cloud servers for using.Not only does it speed up responsing the real-time requests,but also ensures the safe storage of information for users. Experimental analysis clarifies the feasibility of the proposal and reliability of data analysis and processing mode of the bicycle-sharing system based on blockchain and edge-computing.
