A Cluster-based Mechanism for Vehicular Networks in the Scale-Free ICN Core Network

The repetition of content requests happens frequently in the vehicular networks, and it is increasing depending on the vehicular density in a certain area. On the other hand, information-centric networking (ICN) is being used in the vehicular networks to fulfill the faster content communication requirements, reduce latency, and enhance the network capacity. Although, the ICN-based vehicular networks have many benefits, it has several drawbacks, e.g., interest packet flooding, inefficient content caching, and so on. Moreover, the network scalability is related to the drawbacks of the existing ICN-based vehicular networks. It is also important that the current Internet architecture is considered as a scale-free network. Therefore, the solution of the existing drawbacks can be solved using the concept of the scale-free ICN network. In this paper, we propose a cluster-based mechanism for vehicular networks in the scale-free ICN core networks. We also simulate the various scenarios of a scale-free network and show the comparative analysis of different scenarios in terms of the total number of clusters vs the number of nodes in a cluster. Our simulation result ensures the solution to the interest flooding problem and the efficiency of the content caching mechanism.
