Content Cognizant Data Dissemination

Introduction:

This software provides a technique for retrieving dynamic data-such as real time weather forecasting information, share market information etc. It maintains the freshness of the data from source to client. For this we use some algorithm which is intelligent enough to recognize the changes made at the source.  In addition to recognizing it also transfers data from source to the users only at that time when the change is made instead of continuous transmission of data. This helps to improve the performance in terms of the bandwidth required.

Existing System:

In the current scenario there is no system by means of which the dynamic change that happens in the website will be known to the user. In this way the user could keep track of the new details in the website and remain up to date. By using the proposed system the user will always be aware of the changes the moment it takes place in the website.

Proposed System:


We consider techniques for disseminating dynamic data - such as stock prices, real time weather information - efficiently from sources to the clients. If the network lying in middle were intelligent enough to recognize when the data is changing so that it transfers the data from source to client only at that time, it would result in significant improve in performance in terms of bandwidth required and freshness of data. We use a adaptive proxy middle ware to simulate this. The proxy lying in between source and client use intelligent algorithm to estimate how frequently the changes should be transferred. Also which changes should be transferred to which clients according to their coherency requirements. Cooperation between such proxies help reduce system wide communication and computation overheads for coherency maintenance.
