论文摘要
频繁拓扑变化和节点迁移率引起的车辆临时网络（VANET）的动态性质对车辆通信构成了关键的挑战。由于有限的带宽，车辆之间的信息传播大量，VANET的拓扑动态导致交流渠道充血，这是问题下降，延迟和退化服务质量等问题的主要原因。为了减轻这些问题，需要将拥堵检测和控制技术纳入车辆网络。拥塞控制方法可以是基于国会前或拥塞后策略的开环或闭环。我们介绍了城市和高速公路环境中车辆通信的一般建筑，以及对最近的拥塞检测和控制技术的最新调查。我们还确定了现有方法的缺点，并根据不同的层次结构方案对它们进行分类。通过广泛的文献综述，我们建议解决方案方法和未来处理车辆通信中拥塞的方向。
The dynamic nature of vehicular ad hoc network (VANET) induced by frequent topology changes and node mobility, imposes critical challenges for vehicular communications. Aggravated by the high volume of information dissemination among vehicles over limited bandwidth, the topological dynamics of VANET causes congestion in the communication channel, which is the primary cause of problems such as message drop, delay, and degraded quality of service. To mitigate these problems, congestion detection, and control techniques are needed to be incorporated in a vehicular network. Congestion control approaches can be either open-loop or closed loop based on pre-congestion or post congestion strategies. We present a general architecture of vehicular communication in urban and highway environment as well as a state-of-the-art survey of recent congestion detection and control techniques. We also identify the drawbacks of existing approaches and classify them according to different hierarchical schemes. Through an extensive literature review, we recommend solution approaches and future directions for handling congestion in vehicular communications.
