5G车联网展望

Overview of Internet of vehicles for 5G

分析了当前结构下车联网的功能特点,结合新兴的5G通信技术,提出了可多网接入与融合的5G车联网体系结构。该结构不同于基于IEEE 802.11p的车联网VANET结构,而是采用D2D技术实现车联网灵活的终端通信。对比了5G车联网和基于IEEE 802.11p的VANET结构中关键技术参数,并分析了5G车联网低时延、频谱和能源的高效利用等特点以及面临的干扰管理和安全方面的挑战。最后,展望了5G车联网在商业和特定环境下的应用与发展趋势。

The functions and characteristics of current IOV（Intemet of vehicles） Interact of vehicles were analyzed. Moreover, combined with 5G communication technology, the architecture of IOV for 5G was proposed to implement access and integration of multi-network. Different from the IEEE 802.1 lp based architecture of VANET, device-to-device （D2D） technology was introduced to achieve flexible terminals communication of IOV. In comparing with VANET based on IEEE 802.11p in terms of key technology parameters, the IOV for 5G possesses the better characteristics in terms of low latency and efficient spectrum utilization, and also need to face new interference management and security challenges. At the end, the application and development trends of IOV for 5G in the business and the specific environment were prospected.
