车联网通信是一种基于车与车、车与路边通信设施的通信技术,其通过传感器技术、信息技术,对人、车、道路交通情况等境况元素的静态或动态信息进行采集、辨别,来解决车联网中的协调通信,从而最终实现人、车、境况的融合,提高交通出行效率,改善城市交通服务,降低社会运行成本。本论文研究的是如何在基于协调通信情况下,改良车联网数据传输可靠性。 Vehicle network communication is a communication technology based on communication facilities between vehicles and vehicles, vehicles and roadsides. Through sensor technology and information technology, it collects and distinguishes static and dynamic information of the condition elements such as people, vehicles and road traffic conditions, So as to solve the problem of coordinated communication in the car networking so as to finally realize the integration of people, vehicles and the situation, improve traffic travel efficiency, improve urban traffic service and reduce social operating costs. This dissertation is about how to improve the reliability of data transmission in IOT based on coordinated communication.
