Inter-Domain Popularity-aware Video Caching in Future Internet Architectures

Abstract

Current TCP/IP based network is suffering from the usage of IP especially in the era of Internet of things (IoT). Recently Content Centric Network (CCN) is proposed as an alternative of the future network architecture. In CCN, data itself, which is authenticated and secured, is a name and can be directly requested at the network level instead of using IP and Domain Name System (DNS). Another difference between CCN and traditional networks is that the routers in CCN have the caching abilities. Then the end users can obtain the data from routers instead of from the remote server if the content has been stored in the router. Hence the overall network performance can be improved by reducing the required transmission hops and the advantage of the CCN caching has been shown in literature. In this paper, we design a new caching policy for the popularity-aware video caching in CCN to handle the 'redundancy' problem in the existing schemes, where the same content may be stored multiple times along the road from server to users, thus leading to a significant performance degradation. Simulations are conducted and we could observe that the proposed scheme performs better comparing with the existing caching policies.

Survey on the Incorporation of NDN/CCN in IoT

“…Another example of consumer-driven caching is in the work of Liu et al [76], where content is cached based on its popularity with consumers (popularity-aware). The work targets the CCN caching decision policy for popular video streaming contents.…”

Energy Efficiency Analysis of ICN Assisted 5G IoT System

“…While prior work focused on the existing network architecture, recently, the information-centric networking (ICN) [9,10] was proposed to redesign the network to cater to the driving force's shift of network evolution from the connection-centric to information-centric [11]. To this end, scholars claim on the Institute of Electrical and Electronics Engineers (IEEE) 5G summit in Silicon Valley that 5G cannot be simply achieved by the existing technologies heretofore.…”

“…The initial work on ICN, however, is mostly restricted to the upper layer and its applications for real time transmission and quality of experience (QoE) maintenance [12]. For instance, the proactive caching for wireless communications applications was investigated in the study of [13], in which the prototype system with hybrid text and contentcentric networking/named data networking (CCN/NDN) [11] protocols was proposed. It was demonstrated that highquality video delivery without interruption for up to 50 users simultaneously can be achieved by this method.…”
