SerVANET: Service Discovery Protocols for Next Generation Vehicular Ad-hoc networks

随着无线通信和移动网络的最新进展，加上加拿大政府对使我们的交通系统比以往任何时候都更安全、更可靠、更高效的兴趣越来越大，一种新的车载自组织网络已经出现，并具有各种应用。我们设想下一代VANet(NGVNs)的几个应用，包括：城市应急响应、道路安全和安保、交通监控、环境感知和驾驶舒适性，仅举几例。然而，在部署NGVNs并成为一种商品之前，仍然有几个悬而未决的问题必须解决。尤其是安全可靠的服务发现，是阻碍下一代网络未来应用广泛部署的主要问题之一。由于链路拓扑的快速变化、车辆的高移动性以及车辆之间频繁的断开连接，移动自组织网络(MANET)已经被广泛研究并提出了几种技术，但这些技术不能直接应用于VANet，特别是在低密度区域。在这个NSERC SerVANet项目中，我们主要致力于为下一代网络开发高效、可扩展、低开销、安全和容错的服务发现基础设施。为此，我们提出了一类新的服务发现技术，以克服基于NGVN的应用的挑战性问题和关键需求。该项目的成果预计将对智能交通系统如何为公共安全和安保以及信息娱乐类应用程序进行设计产生深远影响。拟议的服务发现基础设施将有助于加拿大车辆网络关键应用的开发，并利用当地在这一研究领域的知识。我们和我们的行业合作伙伴相信，NSERC的这项研究建议是及时的，并与加拿大日益增长的道路安全需求和提高司机和乘客的生活质量同步。

With the recent advances in wireless communication and mobile networking coupled with the growing interest of The Government of Canada to make our transportation system safer, more reliable, more efficient than ever, a new kind of vehicular ad hoc networking has emerged with a variety of ITS applications. We envision several applications for the next generation of VANets (NGVNs) that include: urban emergency responses, road safety and security, traffic monitoring, environment-aware, and driving comfort, just to mention a few. However, there are still several open issues that must be resolved before NGVNs are deployed and become a commodity. Secure and reliable service discovery, in particular, is one of the main issues that are delaying the widespread deployment of future application for NGVNs. Service discovery has been widely investigated and several techniques have been proposed for mobile ad-hoc networks (MANETs) that, unfortunately, cannot be directly applied to VANets due to quick changes in link topology, high mobility pattern of vehicles and frequent disconnections among vehicles, especially in low density areas. In this NSERC SerVANet project, we primarily aim at the development of am efficient, scalable, low overhead, secure, and fault-tolerant service discovery infrastructure for NGVNs. To this end, we propose a novel class of service discovery techniques to overcome the challenging issues and critical requirements of NGVN based applications. The outcomes of this project are expected to have a profound impact on how Intelligent Transportation Systems are designed for public safety and security as well as infotainment class of applications. The proposed service discovery infrastructure will contribute to the development of Canada's key applications of vehicular networks and leverage local knowledge in this area of research. We and our Industry partners believe that this NSERC research proposal is timely and is in sync with the increasing demand for safety of Canadian roads and improving the quality of life for drivers and passengers.
