A Hadoop Distributed File System (HDFS) is designed to store very large data sets reliably and to stream those data sets at high bandwidth to user applications. Metadata management is critical to distributed file system. In HDFS architecture, a single master server manages all metadata, while a number of data servers store file data. This architecture can't(More)
A MANET is a wireless network in which nodes can act as sender/receiver or even as intermediaries like routers. Nodes in a MANET may misbehave with an intent to conserve resources. This happens because of limited resources available for each node. This causes a great impact on the entire network performance. The proposed system organizes a MANET in the form(More)
Mining association rules is an essential task for knowledge discovery. From a large amount of data, potentially useful information may be discovered. Association rules are used to discover the relationships of items or attributes among huge data. These rules can be effective in uncovering unknown relationships, providing results that can be the basis of(More)

The development of Mobile WiMAX was considered to fulfill requirements for all major traffic types present today. This means that it will have to support voice, data and video, even simultaneously in real time applications. The hard handoff (HHO) is performed, when the connection to the serving BS is broken before creating the new connection with the target(More)
Now a day, breast cancer is the leading cancer in women. Every year breast cancer deaths are increasing due to the late diagnosis. Breast cancer percentage is high in developed countries as compared to developing countries. Early detection gives a patient chance of longer survival. Also, it helps to reduce the mortality rates in women. Many techniques have(More)
The WiMAX provides high speed internet access through the means of wireless communication. Handoff is one of the Quality of Service (QoS) parameter in the WiMAX network which supports mobility and it is the main demanding research in wireless network. The hard handoff (HHO) is performed when the connection with the SBS is broken before creating the new(More)
Deep Web contents are accessed by queries submitted to Web databases and the returned data records are enwrapped in dynamically generated Web pages (they will be called deep Web pages in this paper). Extracting structured data from deep Web pages is a challenging problem due to the underlying intricate structures of such pages. Until now, a large number of(More)
With the advent of powerful and efficient wireless sensor nodes, the usage of wireless sensor networks (WSN) has been increased greatly. Sensor networks consist of a network of autonomous sensors that can reconfigure themselves so as to sense the environment in the most efficient manner. These nodes are having low power and limited range. Low power implies(More)
