随着网联汽车及其创新应用的快速发展，研究人员对其越来越感兴趣。车辆自组织网络（VANETs）由具有传感能力的互联车辆组成，以交换交通、天气和紧急信息。智能交通系统（ITS）支持车辆之间更好的协调和提供可靠的服务。在VANET中，由于车辆的高机动性，拓扑结构是动态的，因此现有的基于拓扑结构的方案不适合。在本文中，我们探讨了基于位置的路由（PBR）协议的vanet通过提出一个分类。现有的调查文件主要关注PBR方案，但我们进一步关注城市环境中的PBR以及连接感知路由方案。此外，还包括线性规划、遗传算法和基于回归的方案。为了进一步评估PBR方案的优缺点，本文对不同的架构、路径策略和结转策略进行了分类评估。目前，还没有针对泊车作为锚点或连接点守卫的面向fog的VANET的架构。为了满足这一需求，我们提出了一种面向fog的VANET架构，该架构可以通过利用道路交叉口进行路径选择来支持PBR。它还涉及到停车区域内的车辆进行分组传输。此外，我们建议在路口附近使用停放的车辆作为选择护卫车辆和ITS的一种选择。由于没有保护节点，它降低了广泛的前馈通信的概率。在信标或数据信息交换期间，停放车辆的记录也可以在相邻停放车辆上升级。该架构支持更好的分组分发率、端到端延迟、传输时间和通信成本。此外，还探讨了所提出的架构的机遇和挑战，以吸引研究人员进入这一研究领域。
With the rapid growth in connected vehicles and related innovative applications, it is getting keen interest among the researchers. Vehicular ad-hoc networks (VANETs) comprise of interconnected vehicles with sensing capabilities to exchange traffic, weather and emergency information. Intelligent transportation system (ITS) supports better coordination among vehicles and in providing reliable services. In VANET, topology is dynamic due to the high mobility of vehicles, therefore, the existing topology-based schemes are not suitable. In this paper, we have explored position based routing (PBR) protocols for VANETs by presenting a taxonomy. The existing survey papers have focused on PBR schemes but we have further focused on considering PBR for the city environment along with connectivity aware routing schemes. Moreover, linear programming, genetic algorithms, and regression-based schemes are also included. To further evaluate the strengths and weaknesses of PBR schemes, a categorical evaluation of different architectures, path strategies, and carry-forward strategies are presented. Currently, no architecture is presented for FoG-oriented VANET using parked vehicles as guards for anchor points or junctions. To fill this aspiring demand, we have presented a FoG-oriented VANET architecture that can support the PBR by utilizing road junctions for path selection. It also involves the vehicles in the parking area for packet transmission. Further, we have proposed to use parked vehicles near junction as an option for selecting guarding vehicle along with ITS as well. It reduces the probability of extensive carry forward-based communication due to the absence of guarding nodes. The records at parked vehicles can be upgraded at neighboring parked vehicles as well during the beaconing or exchange of data messages. The architecture supports better packet delivery ratios, end-to-end delay, transmission time, and communication cost. Moreover, opportunities and challenges of the proposed architecture are also explored to attract researchers toward this area of research.
