چکیده انگلیسی
Information-centric-networking (ICN) is a promising paradigm to mitigate this challenge as its in-network caching can bring videos closer to users, which can reduce network traffic and video retrieval delay significantly. In this paper, we propose an ICN-based caching approach that considers both the mobility of users and the popularity of videos. While user mobility has rarely been considered in existing works, in this paper, user mobility is exploited to reduce the retrieval delay caused by frequent handoffs. Videos can be retrieved from the router which is directly connected to the base station (BS) instead of the original content provider when a handoff happens. Consequently, the retrieval delay caused by frequent handoffs can be significantly reduced. Simulations results show that our ICN-based approach outperforms the traditional IP-based RAN caching and the cooperation-driven ICN-based caching scheme (CDIC) in terms of retrieval delay and network traffic deduction.
