REVIEW ON IMPLEMENTATION OF MOBILE PHONE CRAWLERS SRASHTI GUPTA 1 & KUNAL GUPTA 2 1 M.Tech. Student, Amity University, Noida, Uttar Pradesh, India 2 Assistant Professor, Amity University, Noida, Uttar Pradesh, India ABSTRACT In this review paper, express an alternative, more efficient advance to the “download-first process-later” approach of presenting search engines by using mobile crawlers. Crawler is a new testing structural design for system monitoring with cross-layer-coordination that make easy assessment of applications and wireless protocols Search engines preserve indices for web documents and provide search facilities by continuously downloading Web pages for processing. The most important benefit of the mobile strategy is that the analysis section of the crawling method is done locally where the data exist in rather than remotely inside the Web search engine. This can extensively decrease network load which can improve the performance of the crawling procedure. This procedure of downloading web pages is recognized as web crawling. Hence it will reduce the Internet traffic and load on the remote site significantly. This system can be executed by the help of java aglets. KEYWORDS: Search Engine, Mobile Crawler, Searching, Database, World Wide Web INTRODUCTION Crawler appears for the alterations for the indexed pages by repeating them and renews its store by removing the previous. The World Wide Web has developed from a few thousand pages in 1993 to more than two billion pages at present. The result of the status of the Web as a global information system is that it is infested with a large amount of data and information and hence resulting useful information on the Web is often a dreary and annoying experience. New equipment and techniques are decisive for brightly searching for practical information on the Web. However, the machines that were made-up to make Web seem less disordered need information and waste a huge power of time in order to collect it. Mobile phone crawlers are an essential part of all search engines and are increasingly becoming important in data mining and other indexing applications. Mobile phone crawlers (also known as spiders, robots, walkers and wanderers) are programs which surf the Web in a methodical, automated manner.
