UCYMICRA: Distributed indexing of the web using migrating crawlers

Abstract

Due to the tremendous increase rate and the high change frequency of Web documents, maintaining an up-to-date index for searching purposes (search engines) is becoming a challenge. The traditional crawling methods are no longer able to catch up with the constantly updating and growing Web. Realizing the problem, in this paper we suggest an alternative distributed crawling method with the use of mobile agents. Our goal is a scalable crawling scheme that minimizes network utilization, keeps up with document changes, employs time realization, and is easily upgradeable. © Springer-Verlag Berlin Heidelberg 2003.
