Deployment of IEEE 802.11p family of protocols in VANET

车辆自组织网络（VANESTO）允许车对车和车对基础设施的通信，目的是提高道路安全和减少道路事故，但它们也可用于分发信息娱乐内容。为了支持VANET应用的发展，美国的FCC已经为专用短程通信（DSRC）分配了带宽，该专用短程通信可以被新兴的IEEE 802.11p标准和IEEE 1609.x族的更高层协议使用。该提案计划研究IEEE 802.11p和IEEE 1609.x协议的功能，并开发算法，可以有效地将该协议集集成到一些新兴的VANET应用。本研究的主要目的是设计、分析和验证可行的解决方案，这些解决方案将（a）使WAVE技术能够在具有非均匀节点速度、密度和连通性的现实城市/农村/公路环境中有效部署;（B）探索WAVE部署用于不同的通信模式，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车载网络之间的互连解决方案。

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.
