In-Network Caching in ICN-based Vehicular Networks: Effectiveness & Performance Evaluation

Many research efforts have been proposed from physical, networking, to application layers over Vehicular Ad hoc Networks (VANETs) to provide more safety and convenience to passengers. However, due to the highly dynamic topologies and frequent disconnections in VANET, various challenges are faced due to the use of IP that effects the data delivery and user experiences. Therefore, a new paradigm namely Information-Centric Networking (ICN) has been proposed aiming to replace the traditional Internet Protocol by using the content name as the pillar element and providing a distributed in-network caching to enhance the data dissemination & access, and reduce the network load & response latency. The use of ICN in a vehicular environment may require different caching placement strategies and replacement policies. To this end, we study, in this paper, the effectiveness of in-network caching for VANET, we simulate and compare various strategies in different scenarios. Furthermore, we provide different research guidelines to enhance the use of caching in such a challenging network.
