摘要车联网属于移动互联网的一个特殊分支,是智能交通系统ITS领域的典型应用,但由于车联网本身的特殊性,如车辆移动速度快,服务要求及时提供,跨区域的服务要求多等,传统的资源下载方法已经很难满足车联网的实际需求。文章提出了一种在车联网环境下热点资源分布存储与下载的机制,根据热点资源本身具有的特性,结合车联网中资源跨区域下载的特点,采用有效的机制减少了资源下载的时间,不仅提高了网络的响应速度,而且提高用户享受车载娱乐效果的同时也改善了车载网络的性能。 Car networking belong to a special branch of the mobile Internet,is a typical application in the field of intelligent transportation system ITS,but due to the special features of the car under the networked environment,such as vehicle movement speed,provide timely service requirements,cross-regional service requirements etc,more traditional resources download method has been difficult to meet the actual demand of car networking.The paper proposes a hot car networking environment download storage and the mechanism of resource distribution,according to the hot itself has the characteristics of resources,combining the characteristics of the vehicle network resources across regions in the download,adopt effective mechanisms to reduce the resource download time,not only improves the response speed of the network,and improve the effect of users to enjoy on-board entertainment as well as improve the performance of the vehicle network.
