Caching content in small-cell networks can reduce the traffic congestion backhaul. In this article, we develop a hybrid caching network comprising of unmanned aerial vehicles (UAVs) and ground base stations (SBSs), where UAVs are preferred because their flexibility elevated platform for line sight. First, derive association probability user affiliated with UAV SBS. Then, successful delivery by ...

Abstract: A Data Grid connects a collection of geographically distributed computational and storage resources that enables users to share data and other resources. Data replication, a technique much discussed by Data Grid researchers in recent years creates multiple copies of file and places them in various locations to shorten file access times. In this paper, a dynamic data replication strate...

In this paper, large-scale content-centric mobile hybrid networks consisting of mobile nodes and static small base stations (SBSs) (or static helper nodes) are studied, where each node moves according to the random walk mobility model and requests a content object from the library independently at random according to a Zipf popularity distribution. Instead of allowing access to content objects ...

Existing solutions for streaming multimedia in the Internet do not scale in terms of object size and number of supported streams. Using separate unicast streams, for example, will overload both network and servers. While caching is the standard technique for improving scalability, existing caching schemes do not support streaming media well. In this paper, we propose a complete solution for cac...

Ubiquitous in-network caching is one of the key aspects of information-centric networking (ICN) which has recently received widespread research interest. In one of the key relevant proposals known as Networking Named Content (NNC), the premise is that leveraging in-network caching to store content in every node it traverses along the delivery path can enhance content delivery. We question such ...

Web caching is a technology that has demonstrated to improve traffic on the Internet. To find out how to implement a Web caching architecture that assures improvements is not an easy task. The problem is more difficult when we are interested in deploying a distributed and cooperative Web caching system. We have found that some cooperative Web caching architectures could be unviable when changes...

The report is organized as follows: section 2 presents a description of texture mapping and a justification for using a cache dedicated to texturing. Section 3 describes the basic texture caching architecture. The rest of the report review the successive improvements to this basic architecture found in the literature: multilevel caching (section 4), prefetching (section 5), parallel texture cac...

Edge-caching has received much attention as an efficient technique to reduce delivery latency and network congestion during peak-traffic times by bringing data closer to end users. Existing works usually design caching algorithms separately from physical layer design. In this paper, we analyse edge-caching wireless networks by taking into account the caching capability when designing the signal...
