Distributed Web Information Tracking

Obviously, the web is an extremely dynamic world i.e. information updates even every second. A lot of pages are added, deleted and modified continuously on the Internet. The web information monitoring system fetches the information from the web continuously, finds some changes by comparing two versions of the same page and then notifies the users about what happened to their concerned pages. The distributed computing technologies are the appropriate way to track those geographically distributed pages. This paper studies the characteristics of such system by considering the parameters of data transferring characteristics during runtime, the load of nodes types in the system and the network time occupied.
