This paper investigates optimal caching placement for wireless femto-caching network. The average bit error rate (BER) is formulated as a function of caching placement under wireless fading. To minimize the average BER, we propose a greedy algorithm finding optimal caching placement with low computational complexity. Exploiting the property of the optimal caching placement which we derive, the ...

In Mobile AdHoc Networks, web caching is the challenging job due to its moving nature of nodes. So we analyze one technique for web caching in Mobile Ad Hoc Networks. MANET stands for Mobile Ad Hoc Network which is an evolving concept. In the development various researches the different aspects of MANET are focused such as routing and caching of data. Among them, the lack of efforts done on web...

In this paper, the edge caching problem in fog radio access networks (F-RAN) is investigated. By maximizing the overall cache hit rate, the edge caching optimization problem is formulated to find the optimal edge caching policy. We consider content popularity in terms of time and space from the perspective of regional users. Taking into account that users request the contents they are intereste...

Caching is a promising solution to satisfy the ongoing explosive demands for multi-media traffics. Recently, Maddah-Ali and Niesen proposed both centralized and decentralized coded caching schemes, which is able to attain significant performance gains over the uncoded caching schemes. Their work indicates that there exists performance gap between the decentralized coded caching scheme and the c...

The Caching pattern describes how to avoid expensive reacquisition of resources by not releasing the resources immediately after their use. The resources retain their identity, are kept in some fast-access storage, and are re-used to avoid having to acquire them again. Note: This pattern appeared in a heavily reworked and updated version in the book Pattern-Oriented Software Architecture — Patt...

Caching web pages at proxies and in web servers' memories can greatly enhance performance. Proxy caching is known to reduce network load and both proxy and server caching can signiicantly decrease latency. Web caching problems have diierent properties than traditional operating systems paging , and cache replacement can beneet by recognizing and exploiting these diierences. We address two aspec...

This paper aims at finding fundamental design principles for hierarchical web caching. An analytical modeling technique is developed to characterize an uncooperative two-level hierarchical caching system where the least recently used (LRU) algorithm is locally run at each cache. With this modeling technique, we are able to identify a characteristic time for each cache, which plays a fundamental...

Peer-to-peer (P2P) web caching has been studied recently as it can exploit local caches of peers for web caching without additional infrastructure. However, dynamic join/leave behaviors or local caching strategies of the peers due to their autonomy in a P2P network may limit the performance of P2P web caching. To overcome these limitations, we propose an effective directory-based P2P web cachin...
