车联网通信系统中数据业务的新型传输策略研究
|
摘要
智能交通系统已成为5G移动通信业务的重要组成部分。在高速车联通信信道中,如何实现车载终端之间更有效的信息交互,是研究相应带宽分配方法与数据传输策略的关键。基于高速道路环境的特点,提出自组织车联网通信系统的新型数据业务传输策略。该策略通过改进通信带宽周期分割方法,即数据业务带宽周期分别由新定义的切换周期、带宽分配周期与数据传输周期构成,更好地满足智能交通与车载互联应用场景下大数据、高速率、低时延的信息化服务需求。
Intelligent transportation systems is an important part of the 5 G mobile communication business.In the high-speed vehicular communication channel, how to achieve more effective information exchange of between vehicles is the key to exploring the corresponding bandwidth allocation and data transmission strategy. Based on characteristics of highway environment, a novel data transmission strategy for vehicular ad-hoc network communication system is proposed. By improving the method of communication bandwidth cycle segmentation, that is, the data bandwidth cycle is composed of newly-defined switching cycle,bandwidth allocation cycle and data transmission cycle, the information service requirements of big data,high bit-rate and low latency in intelligent transportation and internet-of-vehicles application scenarios could be fairly satisfied.
