Information-centric mobile caching network frameworks and caching optimization: a survey <s> Joint optimal deployment strategy of mobile in-network caching <s> Recently, a series of innovative information-centric networking (ICN) architectures have been designed to better address the shift from host-centric end-to-end communication to requester-driven content retrieval. With the explosive increase of mobile data traffic, the mobility issue in ICN is a growing concern and a number of approaches have been proposed to deal with the mobility problem in ICN. Despite the potential advantages of ICN in mobile wireless environments, several significant research challenges remain to be addressed before its widespread deployment, including consistent routing, local cached content discovery, energy efficiency, privacy, security and trust, and practical deployment. In this paper, we present a brief survey on some of the works that have already been done to achieve mobile ICN, and discuss some research issues and challenges. We identify several important aspects of mobile ICN: overview, mobility enabling technologies, information-centric wireless mobile networks, and research challenges. <s> BIB001 </s> Information-centric mobile caching network frameworks and caching optimization: a survey <s> Joint optimal deployment strategy of mobile in-network caching <s> For more than a decade, the inherent drawbacks of current Internet have been calling for its revolutionary designs. The end-to-end model, which was designed for special data transmission in the early age of Internet, is causing troubles everywhere in nowadays content based web services. Consequently, Information Centric Network (ICN) is proposed to solve these problems. As the most permanent clean-slate approach for next generation Internet, ICN has attracted much attention from network researchers in the passed few years. This survey focuses on the current progress of the research work in ICN. It investigates various key aspects such as naming and routing schemes, in-network caching policies, etc., and highlights the benefit of implementing ICN, open research issues and new interests in this domain. <s> BIB002
In-network caching can enhance content delivery by storing content in every node, but such a universal caching strategy is unnecessarily costly and sub-optimal  . Alternative in-network caching strategies have been investigated to enhance the content delivery performance in the respect of reducing network bandwidth consumption, server load and delay experienced by end users, respectively. However, joint optimization including joint caching and routing, joint network/user performance metrics mentioned above under resource constrained conditions is still an open issue. Liu et al.  provides detailed descriptions on content routing based on ICMANET, and presents a concept model for content routing, and categorizes content routing into proactive, reactive and opportunistic types, then analyzes representative schemes, which can be referred to for the study of joint optimization between content routing and caching in ICMANET. In addition, some studies focus on the energy consumption of ICN. The energy efficiency optimization in ICN is widely investigated in BIB001 , and several research works on green ICN are analyzed in BIB002 , which indicates that designing a caching protocol and leveraging the cooperative caching to achieve the trade-off between energy consumption and quality of service still need to be addressed. Furthermore, although the cost of caching contents is declining, the content replacement strategy considering tradeoff between the redundancy of content caching and caching energy consumption in caching network still remains a research direction, especially in large-scale content networks.
