摘要
车联网(VANET:Vehicle Ad-hoc Network)是物联网在汽车领域的一个应用,但是由于车辆的高速移动性,导致网络拓扑变化快,网络环境不稳定,传统的路侧设施(RSU:Road-Side Unit)与车载设备(OBU:On-Board Unit)之间的C/S(客户端与服务器)架构不能为用户提供可靠的服务。本文提出一种在车联网环境中应用MP2P进行车辆间信息传输的架构,该架构采用半分布式的P2P结构,使同一路侧单元覆盖范围内的车辆进行资源共享,减小了路侧单元的带宽压力,从而为用户提供了可靠的服务。
Vehicle networking （ VANET： Vehicle Ad-hoc Network ） is a networking application in the automotive sector.Due to the Elst-,noving vehicle, it is resulting in rapid changes of the network topology, tmstabitily of the network environnlent, and the traditional C/S architecture for connection between roadside facilities （ RSU ： Road-side Unit ） and on-board equipment （ OBU ： C On-Board Unit ） can not provide users with reliable service.This paper presents an MP2P application in a networked environment, and infimnation transmission can he made between the vehicles.This the architecture depends on semi-distributed P2P architecture, making the vehicles share resource information within the coverage of roadside units, reducing the road side unit bandwidth pressure, so as to provide a reliable service.
