- Information dissemination is one of the most important tasks of vehicular networks. Therefore, information-centric networking (ICN) technology is being more and more widely used in vehicular networks due to the connectionless and lightweight characteristics of this networking paradigm. Caching plays an essential role in information-centric networks, but current caching techniques for ICN are not ideal for use in vehicular networks on account of the dynamicity and wireless transmission of vehicular networks. This paper presents a caching approach for ICN-based vehicular networks that takes into account both the dynamicity of vehicular networks and the popularity of the information to be distributed. By introducing the “interval” metric and estimating the popularity of information and current networking conditions of the vehicles on road, cooperative caching among nodes can be realized without exchanging cache management information among them. Simulation results show that the proposed approach can increase the storage space utilization and has low data response time for vehicular networks.

- In an industrial automation environment, there are many sensors generating large volumes of data. Both time-critical data for realtime control as well as less time-critical data for central monitoring and log data need to co-exist in the system with often harsh wireless environments. Thus, available capacity may be low, causing congestion problems and long latencies for by traffic with less stringent timing requirements. In this paper, we consider the feasibility of using Information Centric Networking in industrial automation networks in order to improve efficiency in distribution of data and reduce latency.
