The invention discloses an alliance chain-based wide area road condition information sharing system, which comprises a sensing communication layer, an authentication transaction layer and a block chain network layer, and is characterized in that a vehicle collects road condition information through a sensor and processes the road condition information through an on-board unit (OBU), and the vehicle and an RSU are authenticated and registered as an alliance chain node through a certificate authority (CA). And the vehicle requesting the road condition information issues a transaction in the system, executes a wide-area road condition information sharing algorithm through an intelligent contract, and returns a sharing result to the requesting vehicle. And rewards and punishment are carried out on honest vehicles and malicious vehicles after vehicle verification information is waited. The road condition information sharing system taking the vehicle request road section as the target is established from the demand and benefit of the vehicle, the accuracy of the information can be ensured, and the experience is improved.
本发明公开一种基于联盟链的广域路况信息分享系统,包括感知通信层、认证交易层和区块链网络层,车辆通过传感器收集路况信息,通过车载单元OBU进行处理,车辆和RSU通过证书授权中心CA认证,注册成为联盟链节点。请求路况信息的车辆在系统发布交易,通过智能合约执行广域路况信息分享算法,把分享结果返回给请求车辆。等待车辆验证信息后,对诚实车辆、恶意车辆进行奖惩。本发明从车辆的需求和利益出发,建立以车辆请求路段为目标的路况信息分享系统,本发明能够保证信息的准确度,提升的体验。
