Nowadays, most of the traffic in vehicular networks is relevant to content, so the content-to-requester method could be an ideal solution for vehicular content delivery. However, due to the features of vehicular networks such as high mobility, the content-to-requester paradigm might cause the frequent content delivery failures and increase the content delivery cost. Inspired by the idea that the address-based mechanism can support mobility and reduce content delivery costs, we are motivated to take advantage of the address-based mechanism to achieve the content-to-requester paradigm. Based on this motivation, we propose a vehicular content delivery scheme with mobility support (VCDM). In VCDM, the receiver and provider handovers are achieved so that a receiver can correctly receive the requested content from a provider via one successful content delivery process. Moreover, a location-based address is proposed so that a requester can acquire the content from the nearest provider in a unicast way. Finally, VCDM is analyzed and evaluated, and the data show that VCDM effectively improves the content delivery success rate and reduces the content delivery cost and latency.

如今，车载网络中的大多数流量都与内容有关，因此内容到请求方法可能是车载内容交付的理想解决方案。然而，由于诸如高移动性之类的车载网络的特征，内容到请求范例可能导致频繁的内容传送失败并增加了内容传送成本。受基于地址的机制可以支持移动性并降低内容交付成本这一想法的启发，我们有动力利用基于地址的机制来实现内容到请求的范式。基于这种动机，我们提出了具有移动性支持（VCDM）的车辆内容交付方案。在VCDM中 接收者和提供者的切换得以实现，从而接收者可以通过一个成功的内容交付过程正确地从提供者那里接收所请求的内容。此外，提出了基于位置的地址，以便请求者可以单播方式从最近的提供商获取内容。最后，对VCDM进行了分析和评估，数据表明，VCDM有效地提高了内容交付成功率，降低了内容交付成本和等待时间。
