Abstract

Technological advancements make the Internet of Vehicles (IoV) become reality so that vehicles can access a variety of multimedia data from the Internet. The IoV is a multi-hop network and employs the Internet protocol to acquire multimedia data from the Internet. Since the size of multimedia data is large, it is extremely significant to reduce the data acquisition latency in the IoV. In this paper, we focus on the data acquisition issue in the multi-hop IoV and propose a new data acquisition solution to reduce the data acquisition latency. The main idea of our solution is to employ the single-hop k-anycast model to achieve the data acquisition in the multi-hop IoV. To make the idea work, we propose a multi-address mechanism in order to acquire different data chunks from different optimal k-anycast servers in parallel. The data acquisition latency is quantitatively evaluated. According to the experimental results, our solution substantially reduces the data acquisition latency compared with the existing approach.
