Efficient vehicular content delivery

Abstract

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.
