The use of Vehicular Ad-Hoc Networks (VANETs) is growing nowadays and it includes both roadside-to-vehicle communication (RVC) and inter-vehicle communication (IVC). The purpose of VANETs is to exchange useful information between vehicles and the roadside infrastructures for making an intelligent use of them. There are several possible applications for this technology like: emergency warning system for vehicles, cooperative adaptive cruise control or collision avoidance, among others. The objective of this work is to develop a VANET prototype system for urban environments using IEEE 802.15.4 compliant devices. Simulation-based values of the estimated signal strength and radio link quality values are obtained and compared with measurements in outdoor conditions to validate an implemented VANET system. The results confirm the possibility of implementing low cost vehicular communication networks operating at moderate vehicular speeds.
目前,车联网(VANET)的应用越来越广泛,其中包括路侧到车辆的通信(RVC)和车辆间的通信(IVC)。VANET 的目的是在车辆和路边基础设施之间交换有用的信息,以实现智能利用。这项技术有多种可能的应用,例如:车辆紧急警告系统、协作自适应巡航控制或防撞等。本工作的目的是使用符合 IEEE 802.15.4 标准的设备开发用于城市环境的 VANET 原型系统。基于仿真获得了估计信号强度和无线电链路质量值,并与户外条件下的测量值进行了比较,以验证所实现的 VANET 系统。结果证实了在中等车速下运行的低成本车载通信网络的实现可能性。
