CAREER: Research on Real-time Robust and Secure Communications for Vehicular Ad Hoc Networks

基于车辆自组织网络（VANETs）的车辆间通信可以增强交通安全和交通运行，这一信念推动了该项目的开展。VANET网络不同于一般的移动自组织网络（MANET），因为在关键的高动态环境中对实时、健壮和安全的通信和协调有严格的要求。本项目在研究相邻车辆运行时静态相对位置关系的基础上，解决了接入技术、动态功率控制、鲁棒多跳通信以及安全和隐私提供方面的主要挑战。特别是，该项目将开发新的访问技术方法，实现动态多路径无线信道的高信道可用性，延迟有界动态功率控制，增强高移动性的实时通信，在频繁碎片存在下的鲁棒多跳消息传播，以及促进协作通信和平衡隐私与安全的安全实现。预计VANET通信将为许多新应用打开大门，如交通安全、车辆移动性、交通运营、信息共享、车辆数据采集和机会性无处不在的通信。

CAREER: Research on Real-time Robust and Secure Communications for Vehicular Ad Hoc NetworksThis CAREER project is motivated by the belief that Vehicular Ad Hoc Networks (VANETs) based inter-vehicle communications could enhance traffic safety and traffic operation. VANET networks differ from general mobile ad hoc networks (MANET) because of the stringent requirements on real-time, robust, and secure communications and coordination in a critical highly dynamic environment. Building on research concerning run-time static relative-position relation among neighboring vehicles, this project addresses the major challenges in access technology, dynamic power control, robust multi-hop communication, and security and privacy provisioning. In particular, this project will develop new approaches to access technology enabling high channel availability over dynamic multi-path wireless channels, delay-bounded dynamic power control augmenting real-time communications over high mobility, robust multi-hop message disseminations in the presence of frequent fragmentations, and security implementation promoting cooperative communication and balancing privacy and security. It is envisioned that VANET communications will open the door for many new applications such as traffic safety, vehicular mobility, traffic operation, information sharing, vehicle data acquisition, and opportunistic pervasive communications.
