NeTS: Small: Collaborative Research: Towards Reliable, Energy-Efficient, and Secure Vehicular Networks

通用车联网系统(VNS)将车载自组织网络(VANET)与混合动力汽车(HEV)集成在一起，使智能交通系统(ITS)得到了广泛的应用。由于对VANET的看法不同，现有的大多数研究都是以一种不连贯的方式提供针对具体案例的解决方案，这些解决方案很难整合到一个有效的系统中。该项目旨在通过五个互补的研究途径，以协同的方式开发可靠、节能和安全的VNS：基础设施优化、可靠网络性能的协议设计、高能效的VNS、安全和隐私配置以及虚拟领域试验台开发。该项目预计将通过解决一些基本的研究问题来显著推进VANET研究的最新水平。考虑到移动性、干扰和数据流量动态等复杂问题，开发了分析模型来研究路边基础设施部署、网络协议和控制算法，以实现最佳性能。为了提高多跳车辆网络的吞吐量，研究了动态网络拓扑结构下多无线多信道环境下的吞吐量最优控制问题。通过利用VNET和HEV之间的相互作用来寻求节能解决方案。为保证车载自组网的安全性和保密性，开发了具有较小计算和通信开销的可扩展安全协议。拟议的研究无缝地整合了优化、概率和随机过程、图论、无线网络、混合动力汽车技术以及计算机模拟等领域的研究和教育活动。本课题所提出的研究具有很好的转化为实用的车载自组织网络协议或控制算法的潜力。

The general vehicular networking system (VNS), where the vehicular ad hoc network (VANET) is integrated with hybrid electric vehicles (HEVs), enables a wide range of intelligent transportation system (ITS) applications. With different visions on VANETs, most of the existing studies provide case-specific solutions in an incoherent manner, which can hardly be integrated into an effective system. This project aims at developing a reliable, energy-efficient, and secure VNS with a synergetic approach through five complementary research tracks: infrastructure optimization, protocol design for reliable networking performance, energy-efficient VNS, security and privacy provisioning, and virtual-field testbed development. This project is expected to significantly advance the state of the art of VANET research by addressing some fundamental research issues. Analytical models are developed to study the road-side infrastructure deployment, networking protocols and control algorithms for optimal performance, considering the complex issues of mobility, interference, and data traffic dynamics. The throughput-optimal control in a multi-radio multi-channel context with dynamic network topology is studied to improve the throughput over a multi-hop vehicular network. Energy-efficient solutions are pursued by exploiting the interplay between the VNET and HEVs. Scalable security protocols with small computation and communication overhead are developed to provision security and privacy in VANET. The proposed research seamlessly integrates research and education activities in the areas of optimization, probability and random process, graph theory, wireless networking, HEV technologies, as well as computer simulations. The research proposed in this project has a good potential to be transformed into practical protocols or control algorithms for VANETs.
