This work investigates the problem of content source mobility in Vehicular Named Data Networking (VNDN). We evaluate through experiments the effects of source mobility on VNDN application performance, we analyze the main approaches already proposed in the literature to address its negative impacts and propose a new solution. Our proposed solution combines the concepts of Floating Content (FC) and Home Repository (HR). FC is an infrastructure-less mechanism that relies on in-network caching and content replication to support content sharing within a specific geographic region. An HR is a fixed node that can provide requested content objects on behalf of mobile content sources. Our main goal is to propose an efficient solution for source mobility in VNDN, able to provide high application performance and eliminate the weaknesses of existing approaches such as single points of failure and high overhead in the wireless communication medium.
