Information-centric mobile caching network frameworks and caching optimization: a survey <s> Security and privacy of information-centric mobile caching network <s> This article introduces the idea of ICN-enabled IEEE 802.11 wireless access points (APs) as nano data centers. After elaborating its design, we evaluate the performance with trace-based simulation and prototype-based experiment. The evaluation shows that even a small size cache, e.g. 1Gbyte nearby mobile users can reduce traffic load by 15%, which enables mobile operators to reduce operational cost in the mobile back-haul areas. Moreover, a mobile user can download content files with less delay and interruption, especially when the performance of network becomes degraded or unstable. The synergy between ICN supporting mobility as the norm and widely deployed broadband IEEE 802.11 wireless access points makes this proposal attractive as a potential application scenario for ICN. <s> BIB001 </s> Information-centric mobile caching network frameworks and caching optimization: a survey <s> Security and privacy of information-centric mobile caching network <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 seems not to be attractive for some content providers since it may cause copyright problems or legal issues BIB002 . In open mobile system, security and privacy has been a long-run challenge of much concern, especially in the cooperative caching system where mobile nodes cache contents due to their own limited cache space and energy. In other words, a mobile node can act as a content subscriber which requests contents from cooperative nodes and also play a role of content publisher or a relay node which provides contents to cooperative nodes. The process of cooperative caching brings about severe privacy issues, which is the reason why some mobile users would not like to take part in the caching cooperation. In ICN, content name is required to be included in requests, which would lead to privacy issues. In MANETs, connectivity provided over access points would offer an acceptable level of privacy for users who trust their access points BIB001 . This is particularly challenging in densely connected networks that easily permit packet sniffing. For ubiquitous mobile cache deployment, it is apparent that security and privacy problem needs to be addressed, and it is also worth discussion on combination of technical mechanism and new laws on content propagation during the evolution of ICN and information centric caching.
