Agent-Based Approach for Web Crawling

: Since its creation in 1990, World Wide Web has increased the popularity of Internet which becomes an important source of information or services for all people over the world. The dynamic nature of the Web draws attention to the need for continuous support and updating of Web information retrieval systems. Web crawling is the process of discovery and maintenance of large-scale web data. Crawlers achieve this process by following the Web pages hyperlinks to automatically download a partial snapshot of the Web. In this paper, an agent-based approach, through three scenarios, for parallel and distributed Web crawling is presented. Simulations with ns2 show that the cloning based mobile agents scenario outperforms the single and multiple mobile agents scenarios.
