Deployment of IEEE 802.11p family of protocols in VANET

车载自组织网络(VANET)允许车到车和车到基础设施的通信，目的是改善道路安全和减少道路事故，但它们也可以用于分发信息娱乐内容。为了支持VANET应用的开发，美国的FCC已经为专用短程通信(DSRC)分配了带宽，该带宽可用于新兴的IEEE 802.11p标准和IEEE 1609.x系列的更高层协议。该提案计划研究IEEE 802.11p和IEEE 1609.x协议的特点，并开发能够有效地将该协议套件集成到许多新兴的VANET应用中的算法。拟议研究的主要目标是设计、分析和验证可行的解决方案，以(A)使WAVE技术能够在具有不均匀节点速度、密度和连通性的现实城市/农村/公路环境中有效地部署；(B)探索针对不同通信模式的WAVE部署，例如信标、广播、单播和存储转发；以及(C)开发车载传感器网络和VANET之间的互联解决方案。

Vehicular ad hoc networks (VANETs) allow car-to-car and car-to-infrastructure communications with the aim of improving road safety and reducing road accidents, but they can be used to distribute infotainment content as well. To support the development of VANET application, the FCC in the United States has already allocated bandwidth for dedicated short-range communications (DSRC) that can be used by the emerging IEEE 802.11p standard and higher layer protocols of the IEEE 1609.x family. This proposal plans to investigate the features of IEEE 802.11p and IEEE 1609.x protocols, and to develop algorithms which can efficiently integrate this protocol suite into a number of emerging VANET applications. The main objective of the proposed research is to design, analyze, and validate feasible solutions that would (a) enable efficient deployment of WAVE technology in realistic city/rural/highway environments characterized with non-uniform node velocity, density and connectivity; (b) explore WAVE deployment for different communication patterns such as beaconing, broadcast, unicast and store-and-forward; and (c) develop interconnection solutions between car-based sensor networks and VANETs.
