Content Centric Network System and Its Application in Internet of Vessels

In this paper, we propose a method for building ship-based information system by utilizing the newly developed content centric network. The structure of the content centric network is described and the corresponding simulation model is built by taking the ship-based data transmission system as the research target. Extensive evaluation of the model is performed by analyzing the content cache-hit ratio, the server load, the system transfer speed, and the number of routing hops required to complete a data transfer. The simulation results show the advantages of the content centric network over conventional IP networks and verify the feasibility of applications of content centric network technology in Internet of Vessels.
