To improve the performance of web database access for regular users, we have developed a client caching agent, referred to as a personal assistant. In addition to caching strategies based on data characteristics and user specification, the personal assistant dynamically prefetches information based on previously monitored user access patterns. It is part of an overall multi-layered caching sche...

In this paper, we propose a dynamic multicasting policy based on the phased proxy caching to reduce the network bandwidth from the central server to the clients. In the proposed multicasting policy, for an object, a multicasting channel is allocated only if there are more than two active unicast streams for that object. So, the length of a multicasting window varies with the arrival rate of tha...

This paper discusses the representation and caching of medical data structured and stored as XML documents. Caching of XML medical data is proposed towards improving the medical data accessibility and availability. The representation of XML medical data is a tree like structure and the caching process is guided by frequency of access of the XML medical data records. Experimentation is carried o...

Departing from the conventional cache hit optimization in cache-enabled wireless networks, we consider an alternative optimization approach for the probabilistic caching placement in stochastic wireless D2D caching networks taking into account the reliability of D2D transmissions. Using tools from stochastic geometry, we provide a closed-form approximation of cache-aided throughput, which measu...

In a Fog Radio Access Network (Fog-RAN), edge caching is combined with cloud-aided transmission in order to compensate for the limited hit probability of the caches at the base stations (BSs). Unlike the typical wired scenarios studied in the networking literature in which entire files are typically cached, recent research has suggested that fractional caching at the BSs of a wireless system ca...

The centralized coded caching scheme is a technique proposed by Maddah-Ali and Niesen as a solution to reduce the network burden in peak times in a wireless network system. Yan et al. reformulate the problem as designing a corresponding placement delivery array and propose two new schemes from this perspective. These schemes above significantly reduce the transmission rate R, compared with the ...

Recently, there are significant advances in the areas of networking, caching and computing. Nevertheless, these three important areas have traditionally been addressed separately in the existing research. In this paper, we present a novel framework that integrates networking, caching and computing in a systematic way and enables dynamic orchestration of these three resources to improve the end-...

Caching dynamic content can bring many benefits to the performance and scalability of Web application servers. However, such mechanisms are usually tightly coupled to individual application servers (or even applications) that prevent caching at more advantageous points. In this paper we propose an approach to enable dynamic content caching at enhanced Web proxies which requires only simple modi...
