An analysis of caching in information-centric vehicular networks

Information-centric networking is poised as an alternative to the address based network model, being mobility friendly and allowing for improved caching. However, VANETs, one of the biggest trends in ad-hoc networking, are defined by their peculiarities and pose additional challenges to the implementation of caching systems. The volatile nature of VANETs requires the development of specialized solutions, tailored for highly mobile environments. Towards the definition of efficient caching policies for ICN-VANETS, in this work, we discuss the current state of ICN caching in VANET, the potential hurdles that need to be overcome. We perform a series of simulations and analyze the efficiency of popular caching in various network configurations to denote current shortcomings and pinpoint potential areas where caching can be improved.
