Abstract
Vehicular Ad hoc Networks (VANETs) have been providing promising solutions for both the safety and non-safety requirements of 21st century drivers. Since, the number of vehicles are increasing, the current host centric communication approach faces various challenges. On the other hand, the Information Centric Networking (ICN) concept in vehicular communications aims to achieve content retrieval in the dynamic and error prone environment. Recently, the concept Vehicular ICN (VICN), has been explored extensively by researchers, leading to a number of open challenges such as, content naming, name resolution, Interest forwarding strategies, content store, forwarding information base and pending interest table management, security and trust issues, etc. In this paper, we therefore discuss the recent advancements in different VICN approaches with more focus on the Interest forwarding strategies which have been applied during the content retrieval process.
