In this paper, we present a mobile streaming media CDN (Content Delivery Network) architecture in which content segmentation, request routing, pre-fetch scheduling, and session handoff are controlled by SMIL (Synchronized Multimedia Integrated Language) modification. In this architecture, mobile clients simply follow modified SMIL files downloaded from a streaming portal server; these modifications enable multimedia content to be delivered to the mobile clients from the best surrogates in the CDN. The key components of this architecture are 1) content segmentation with SMIL modification, 2) on-demand rewriting of URLs in SMIL, 3) pre-fetch scheduling based on timing information derived from SMIL, 4) SMIL updates by SOAP (Simple Object Access Protocol) messaging for session handoffs due to clients mobility. We also introduce QoS control with a network agent called an "RTP monitoring agent" to enable appropriate control of media quality based on both network congestion and radio link conditions. The current status of our prototyping on a mobile QoS testbed "MOBIQ" is reported in this paper. We are currently designing the SOAP-based APIs (Application Programmable Interfaces) needed for the mobile streaming media CDN and building the CDN over the current testbed.

Environmentally-adaptive XML transformation is a key goal for content adaptation. It needs a standard and computationally efficient framework for transformation engine than can transform input XML data depending on environment descriptions (e.g., terminal capabilities) and rule descriptions (e.g., access policies). We propose a method to realize the framework. We adopt XSLT and DOM processors: the DOM processors use environment descriptions and rule descriptions in composing XSLT instances; the XSLT processors refer to the XSLT instances in transforming the input XML data. We cache the XSLT instances for reuse. Since one XSLT instance is produced for each environment description, their number is manageable; XSLT instances are not necessarily created for every input. Caching the XSLT instances and reducing the number of XSLT instances created yields a significant computational advantage in large-scale multimedia content delivery. We will use the proposed framework to create an AAA (Authentication, Authorization, and Accounting) system for multimedia content delivery and network control.

In this information age, searching for information from the internet becomes wide spread, but some of the valuable information are hidden behind dynamically generated page which the search engines never crawled. It becomes imperative to find a way of making them available. This research work provides a scalable framework for locating forms that serves as the entry point for information in web databases. The methodology focuses on the link classifier by using Path-Ascending algorithm which has the advantage of searching as many resources as possible from a particular site, since forms are sparsely distributed, After implementing this framework, it was observed that the framework searches more than 90% of the links in each site tested which is comparatively higher than using search algorithm in the link classifier. This framework suggest using path ascending algorithm in the link classifier which make the crawler to search almost all the links on each page of a site providing a better opportunity to locate a searchable form. Crawler: a program that systematically browse the world wide web in order to create an index of data, deep web: information buried far down on dynamically generated sites, and standard search engines never find it, Frontier:it consist of URL and Crawling modules used to crawl the web pages to extract the meta data,surface web: information that common search engines like Google, Yahoo, AltaVista, Ask, and Bing can crawl.
