Demo: Vehicular Micro Cloud Assisted Collaborative High-Definition Map Downloading

Vehicular Micro Cloud (VMC) is a group of connected vehicles where they collaborate over vehicular networks. One potential use case of a VMC is a collaborative downloading service in which vehicles download data contents from a remote server and form VMCs to share them with other vehicles. In this paper, we study the feasibility of collaboratively downloading high-definition (HD) maps among VMC members. We demonstrate the benefits through field trials with multiple test vehicles. Our outdoor experiments showed that VMC-assisted collaborative downloading could reduce the communication overhead associated with HD map updates.
