“…Dynamic web pages are created on request by application programs stored in the back-end site infrastructure, caching of dynamic web pages are essential for improving the performance of web sites containing significant dynamic content and information personalized to individual users [38]. Dynamic content has three forms of locality: identical requests, equivalent requests and partially equivalent requests.…”

Increasing popularity of the World Wide Web over the past few years has imposed a significant traffic burden upon the internet. The continued increase in demand for objects on the internet causes severe overloading in many sites and network links. Web traffic reduction techniques are mandatory for accessing the websites efficiently. Data caching and prefetching techniques play a key role in improving the web performance in mobile information systems. Generally the mobile devices have less amount of memory storage than computers. Therefore the key challenge in prefetching is to determine 'what to prefetch' so that the improvement in performance will be enhanced. In a mobile environment the mobility brings the new challenges to the prefetch problem.

“…The real-time data collection problem bears some similarity to dynamic Web content caching [26], [27], [28], [29], [30] at a higher level. Since changes to underlying data might affect more than one Web page, the key issues in dynamic Web content caching are to determine what dynamic pages should be cached and when a cached page has become obsolete.…”

Abstract-In the future, we are likely to see a tremendous need for context-aware applications which adapt to available context information such as physical surroundings, network, or system conditions. We aim to provide a fundamental support for these applications-a real-time context information collection service. This service delivers the right context information to the right user at the right time. The complexity of providing the real-time context information service arises from 1) the dynamically changing status of information sources, 2) the diverse user requirements in terms of data accuracy and service latency, and 3) constantly changing system conditions. In this paper, we take into consideration these dynamics and focus on addressing the trade-offs between timeliness, accuracy, and cost for information collection in distributed real-time environments. We propose a middleware-based approach to enable a judicious composition of services for accuracy-aware scheduling and cost-aware database maintenance. Specifically, we characterize the problem in terms of Quality-of-Service Satisfaction (QoSSat), Quality-of-Data Satisfaction (QoDSat), and Cost. We propose a middleware framework for the real-time information collection process, where the information mediator coordinates and facilitates communication between information sources and consumers. We design a family of algorithms for real-time request scheduling, request servicing, and directory service maintenance to be implemented at the mediator to support QoSSat and QoDSat. Our studies indicate that the composition of our proposed scheduling algorithm and directory service maintenance policy can improve the overall efficiency of the system. We also observe that the proposed policies perform very well as the system scales in the number of information sources and consumer requests.

“…Our study is more general than the studies described in [11] and [14] in that we predict the behavior of Web pages as a function of the behavior of their constituting objects rather than deriving the models from the observed behavior of the pages.…”

“…In particular, the files tend to change little when they are modified and modification events tend to concentrate on a small number of files. The stochastic properties of the dynamic page update patterns and their interactions with the corresponding request patterns are studied in [11]. This study shows that the pages of highly dynamic sport sites are characterized by a large burst of updates and by a periodic behavior.…”

Abstract. Web sites have become increasingly complex and offer a large variety of services and contents. The proliferation of dynamic Web contents opens up new challenging performance and scalability issues. This paper addresses the characterization of dynamic Web contents by studying their update process. We identify parameters and metrics that describe the properties of Web pages and we derive an analytical model that captures their behavior. The model is then validated against simulation experiments.
