The Internet of Things (IoT) connects every object equipped with computing and communication power and provides interaction between the objects to accomplish a task. The Internet of Vehicles (IoV) is a key component of IoT. In IoV, the messages communicated between the vehicles, the infrastructure or the wearable should be reliable and has to be communicated within a short span of time. Existing literatures rely on layered architecture which mainly lies towards IoT architecture. Since in IoV, speed is an important factor and messages should be verified for authenticity, privacy and security becomes an important concern. In this paper, privacy preserved and secured four layer architecture is proposed with its protocol stack and future directions. Performance analysis with existing architecture is compared. By adopting the privacy preserved approach, the analysis shows that the proposed scheme PPSA provides better throughput, Packet Delivery Ratio and End-to-end delay.

物联网（IoT）连接具有计算和通信能力的每个对象，并提供对象之间的交互以完成任务。车联网（IoV）是物联网的关键组成部分。在IoV中，车辆，基础设施或可穿戴设备之间传递的消息应该可靠，并且必须在短时间内传递。现有文献依赖于主要面向物联网架构的分层架构。由于在IoV中，速度是一个重要因素，因此应验证消息的真实性，隐私性和安全性是一个重要问题。本文提出了一种具有隐私保护功能的四层体系结构及其协议栈和未来发展方向。比较了现有架构的性能分析。通过采用隐私保护方法，
