Keeping Information Alive: Hovering Information and Floating Content Paradigms for Vehicular Networks

Hovering Information and Floating Content are two sub-domains of information dissemination which aim to keep information persistent in a region where vehicle to vehicle (V2V) communication is the only option. In this mutual goal to keep information alive, both sub-domains have sought to design algorithms that overcome the geographical and technological challenges while maintaining efficient resource management. Techniques have arising which stem from flooding and broadcasting techniques, probabilistic communication, and using machine learning to direct communication. This work will examine the state-of-the-art works within both sub-domains to bring the reader to a respectable level of knowledge, and offer insight into the future directions research in the area may take.
