摘　　要：在车联网进行内容分发时,因为使用同等网络带宽资源传输内容,业务高峰期时会发生网络拥堵,导致热点资源无法被快速下载,使得用户体验下降,针对这些问题提出一种基于热度统计的车联网内容传输带宽动态分配方法,对内容资源进行自动热度统计和管理,并据此调整不同热度资源的传输带宽,实现热点资源的高速传输,从而提高终端车辆上的多媒体等大流量业务的用户感知。When delivering contents through the internet of vehicles,network congestion may occur during peak hours of the business,which resulting in the inability to quickly download hot resources and a decrease in user experience,due to the use of equal network bandwidth resources to transmit contents.A dynamic allocation method for content transmission bandwidth of internet of vehicles based on the popularity statistics is proposed to address these issues.Automatic popularity statistics and management of content resources are carried out,and the transmission bandwidth of different popularity resources is adjusted accordingly to achieve high-speed transmission of popularity resources,thereby improving users’perception of multimedia and other high-traffic services on terminal vehicles.
