Abstract
In Content-Centric Networking, content caching is a critical issue. At present, most researches on content network caching mainly focus on network resource utilization, while user interest is neglected. In this paper, we propose a caching strategy based on user interest in the Content-Centric Networking. Firstly, it divides the users into several interest groups. Then get the appropriate caching probability for each node by using grey relational analysis method. Simulation results show that the caching strategy proposed in this paper can achieve higher cache hit ratio and less average hop count than Leave copy everywhere (LCE) and ProbCache.
