Mobile ad hoc network is a self-directed structure of mobile nodes connected by wireless links. All nodes operate not only as an end system, but also as work as a router to forward the packets. Ad hoc wireless networks are characterized by multi-hop wireless connectivity, infrastructure less and habitually changing topology. It may be necessary for one(More)
Mobile Ad hoc networks are recent wireless networking model for cellular phone hosts. Ad hoc networks do not rely on any stable infrastructure because they are independent. As an alternative, to remain network connected hosts rely on each other. It signifies complex distributed systems that encompass wireless mobile nodes. These nodes can freely and(More)
Traditional caches see a fixed-size page; a Web cache, on the other hand, sees complete objects (text files, images, or video clips), which vary considerably in size. In addition, a traditional cache deals with addresses, while a Web cache can potentially deduce more contextual information from its objects. Web objects are predominantly read-only, taking(More)
Outlier detection has been attracting the data analysts in almost every domain for a long time now because their detection is very challenging. Outliers or novel cases need to be detected before any analysis is performed on data set. Depending upon the domain, outlier detection saves a lot of time, money or both. In this paper, we developed a novel outlier(More)
Web Data Mining is an important area of Data Mining which deals with the extraction of interesting knowledge from the World Wide Web. It defines the application of data mining techniques to extract knowledge from web data, including web documents, hyperlinks between documents, usage logs of web sites, etc. Therefore, the process of extracting useful(More)
H1N1 pandemic posed a serious threat to world health community and was a cause of serious concerns of various governments worldwide. The aim of the study was to study the Epidemiology of H1N1 in western Rajasthan from August 2009 to March 2010. This study was conducted in hospitals attached to Dr. S. N. Medical College, Jodhpur. This retrospective(More)
Internet today has become a victim of its own success. As the internet is reaching a global community, the World Wide Web is becoming a global-scale data dissemination system. There has been an increase in user latency, bandwidth utilization and server loads because of the increased number of World Wide Web users. Web caching is a technology for overcoming(More)
Web mining is the application of data mining techniques to extract knowledge from web data, including web documents, hyperlinks between documents, usage logs of web sites, etc. The process of extracting useful information from the contents of web document is data mining. Content data is the collection of facts a web page is designed to contain. It may(More)
In mobile ad hoc networks, there is no fixed infrastructure to observe or assign the resources used by the mobile nodes. The nonexistence of any essential controller makes the routing a versatile one compared to cellular networks. The Ad hoc On Demand Distance Vector (AODV) routing algorithm is a routing protocol intended for ad hoc mobile devices. Due to(More)
An optimum DFT-modulated filter bank with sharp transition band as a non-linear optimization has been formulated .The design of this filter is very expensive by the standard method ,and hence the frequency response masking(FRM) technique is developed so as to reduce the complexity in the design process. An effective approach is proposed to solve this(More)
