Collaborative Research: CSR-DMSS: On-road Real-time Information Systems for driving safety atop VANET-WSM symbiosis

提高驾驶安全性一直是车载自组织网络（VANETs）的首要目标。然而，在没有前方车辆的情况下缺乏感知，以及VANETs特有的频繁网络断开，可能会导致驾驶危险：这些网络不能很准确地检测危险路况，也不能保证及时传播警报信息。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共生架构。在该架构中，传感器节点沿着道路两侧部署，以检测危险路况，并促进车辆之间的及时信息共享；反过来，vanet提供了更丰富的计算、通信、存储和功耗资源，帮助wsn克服资源限制。在这种共生关系的基础上，可以部署更有效的安全驾驶道路信息系统。该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架构的可行性和性能。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。这项研究预计将产生第一手的实验结果，从而更准确、更全面地理解VANET-WSN共生架构背后的科学和工程原理，从而有助于开发新的实用技术，显著提高驾驶安全性。

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.
