-Intelligent prefetchmg helps to reduce the
perceived delay for document downloading at the user's
end. A monitor agent predicts possible future requests that
are then prefetched to a proxy server near the user. An
independent cache is provided for all users at the proxy
server side. The documents are prefetc ....etc

Abstract
Some recent studies have shown that cooperative cache can improve the system performance in wireless P2P networkssuch as ad hoc networks and mesh networks. However, all these studies are at a very high level, leaving many design andimplementation issues unanswered. In this paper, we present our design and implementation of cooperative cache in wireless P2Pnetworks, and propose solutions to find the best place to cache the data. We propose a novel asymmetric cooperative cache approach,where the data requests are transmitted to ....etc

The performance of caching systems in general, and Internet caches in particular, is evaluated by means of the user-perceived service speed, reliability of downloaded content, and system scalability. In this dissertation, we focus on optimizing the speed of service, as well as on evaluating the reliability and quality of data sent to users. In order to optimize the service speed, we seek optimal replacement policies in the first part of the dissertation, as it is well known that download delays are a direct product of document availability at ....etc

BENEFIT-BASED DATA CACHING IN AD HOC NETWORKS-MOBILE COMPUTING

Data caching can significantly improve the efficiency of information access in a wireless ad hoc network by reducing the access latency and bandwidth usage. However, designing efficient distributed caching algorithms is non-trivial when network nodes have limited memory. In this article, we consider the cache placement problem of minimizing total data access cost in ad hoc networks with multiple data items and nodes with limited memory capacity. The above optimization problem is ....etc

Development of a HTTP Caching Proxy Server




A proxy acts as an intermediary agent between its clients and the servers which they want to access, performing functions directed towards a variety of purposes, like security, caching, etc, in its capacity as an intermediary. Specifically, caching HTTP Proxy Servers are intermediate servers, which maintain a cache of Internet objects like html files, image files, etc which are obtained via HTTP.

The Internet Cache Protocol (ICP) is a protocol used for coordinating web caches. Its purpose is to find out the most appropriate location to retrieve a requested object from in the situation where multiple caches are in use at a single site. The goal is to use the caches as efficiently as possible, and to minimize the number of remote requests to the originating server

Integrating Web Caching and Web Prefetching in Client-side Proxies (VB.NET)
IEEE Transactions on Parallel and Distributed Systems, Vol. 16, No. 5,

Abstract:
Web caching and Web prefetching are two important techniques used to reduce the noticeable response time perceived by users. Note that by integrating Web caching and Web prefetching, these two techniques can complement each other since the Web caching technique exploits the temporal locality, whereas Web prefetching technique utilizes the spatial locality of Web objects. Howeve ....etc

Caching popular objects close to the users provides an opportunity to combat this latency by allowing users to fetch data from a nearby cache rather than from a distant server. Web caching has been recognized as one of the effective schemes to alleviate the service bottleneck and reduce the network traffic, thereby minimize the user access latency ....etc

Abstract
This paper introduces a cooperation-based database caching system for Mobile Ad Hoc Networks (MANETs). The heart ofthe system is the nodes that cache submitted queries. The queries are used as indexes to data cached in nodes that previouslyrequested them. We discuss how the system is formed and how the requested data is found if cached or retrieved from the externaldatabase and then cached. Analysis is performed, and expressions are derived for the different parameters, including the upper andlower bounds for the number of que ....etc
