Abstract

Search engines store information locally with the purpose of deliver quick, accessible search abilities. This information is collected by Web crawler. Web crawling is necessary for the maintenance of complete and latest web document gathering for a web search tool. The web document modifies its content on regular basis hence it becomes necessary to build up a successful framework which could identify these sorts of changes proficiently in the most minimal scanning time to accomplish this modifications. The essential thought behind designing of such a web crawler is to find high quality web documents within limited time frame. The proposed system works on the Client-Server Technology it reduces the overlap problem and downloads high quality web pages. We can add many web crawler in parallel to download web page in parallel way.

Keywords

Client-Server Technology, Overlap, Search Engine, Web Crawler, Web Page.

Abstract

Objective: This paper tries to devise a new algorithm based on ACO as well as multipath routing in Adhoc Multipath Distance Vector (AOMDV) environment. Methods/Statistical Analysis: Routing is a technique of transmitting data from source node to the destination node. Path breaks frequently in MANET due to the moving nodes. Multipath Routing presents a solution towards this problem, because of the presence of alternative paths. So, communication does not halt. Ant Colony Optimization (ACO) is a newer field of swarm intelligence to tackle optimization problems. Findings: The new algorithm is named A-AOMDV and is compared with other multipath and unipath protocols. Some of the performance metrics are chosen to compare and evaluate the new routing algorithm with traditional algorithms like Throughput, Jitter, Number of packets send, End to End Delay, Packet Lost, Delivery Ratio. Based upon the obtained results, the comparison graphs have also been made while evaluating parameters. The results are very encouraging and the new algorithm has outperformed other algorithms used for the purpose of comparison. Applications: Data communication can take place through alternative paths using efficient multipath routing protocol and easily tackle problems of disconnections during data communication.

Abstract

Objective: The purpose of the paper is to compare the various protocols of different categories in Mobile Adhoc Networks (MANETs). Analysis: The wireless networks are promising as future technology which will be going to be the highest demanded source of communication. MANETs is one of the wireless technologies which make use of intermediate nodes in order to transport the data from the starting place to destination. All the transitional joints operate as a router which can decide the path for the movement of the data packets. Findings: This paper helps us in revising the available technologies on the basis of various parameters illustrated in the last section of the paper. A healthy comparison is made between AODV, DSR, DSDV, TORA, CGSR, WRP and ZRP on the basis of various parameters. These algorithms are compared in an exhaustive way in section 7 by considering 16 parameters like time complexity, communication complexity, advantages and disadvantages etc. as can see in table 2. Applications: After indepth knowledge, one can easily apply these protocols in various applications like military rescue, Pocket switched networks, and personal application networks etc. according to their characteristics.
