Improving driving safety has been a top objective for vehicular ad hoc networks (VANETs). However, the lack of sensing in the absence of cars ahead on the road and frequent network disconnections specific to VANETs could lead to driving hazards: These networks cannot detect dangerous road conditions with good accuracy and cannot guarantee timely propagation of alert messages. To address these problems, this research proposes to merge inexpensive wireless sensor networks (WSNs) with VANETs to create a VANET-WSN symbiotic architecture. In this architecture, sensor nodes are deployed along road sides to detect dangerous road conditions and facilitate timely information sharing among vehicles; in return, VANETs provide richer computation, communication, storage, and power resources to help WSNs overcome their resource constraints. On top of this symbiosis, more effective on-road information systems for safe driving can be deployed. The main objective of this project is to explore the design and implementation of a prototype VANET-WSN symbiotic system and conduct research to test and measure the feasibility and performance of the proposed architecture. Additionally, a number of real applications built and evaluated on top of this architecture help identify and address architectural challenges in supporting application development and deployment. This research is anticipated to produce first-hand experimental results that will lead to a more accurate and comprehensive understanding of the scientific and engineering principles behind the VANET-WSN symbiotic architecture, and thus will contribute to developing new and practical technologies for significantly improved driving safety.

提高驾驶安全性一直是车载自组网(VANET)的首要目标。然而，在道路上没有汽车的情况下缺乏感知，以及VANET特有的频繁网络断开可能会导致驾驶危险：这些网络无法很好地准确检测危险的路况，也无法保证警报消息的及时传播。为了解决这些问题，本研究提出将廉价的无线传感器网络(WSN)与VANET合并，以创建VANET-WSN共生体系结构。在该体系结构中，传感器节点部署在路侧，以检测危险路况并促进车辆之间的及时信息共享；作为回报，车载自组织网络提供更丰富的计算、通信、存储和功率资源，帮助无线传感器网络克服其资源限制。在这种共生关系的基础上，可以部署更有效的道路安全驾驶信息系统。本项目的主要目标是探索VANET-WSN共生系统原型的设计和实现，并进行研究以测试和测量所提出的体系结构的可行性和性能。此外，在此体系结构之上构建和评估的许多实际应用程序有助于识别和解决支持应用程序开发和部署的体系结构挑战。预计这项研究将产生第一手实验结果，使人们更准确和全面地了解VANET-WSN共生体系结构背后的科学和工程原理，从而有助于开发新的实用技术，显著提高驾驶安全。
