Wireless Sensor Networks(WSNs) are composed of inexpensive, low powered microsensor nodes capable of sensing, processing and communicating with limited computational, low bandwidth and resources. WSNs are infra-structureless networks where the topology is based on the Type of Sink, number of hops, types of nodes and type of scheduling. The sensor nodes self-organize themselves dynamically to form a network and communications between nodes are established through broadcasting using radio signals. Research issues include connectivity, coverage, QoS, energy consumption, security and mobility of...

World Wide Web (WWW) is a collection of interconnected Web pages accessed via Internet offering information and services from all over the world. There is an explosive growth of information in the Web that poses a challenge to Web users to extract essential knowledge from it. Web Mining is a process of extracting knowledge from WWW using Data mining Techniques. The Web contains Semistructured data like Web pages and Web logs. Mining of Semistructured data involves, (i) extraction of required information from the Deep Web which is not accessible to the search engines, (ii) careful...

The recent advances & development of inexpensive computers & high speed networking technology have enabled the Video-on-Demand (VoD) application to connect to shared-computing services. VoD has important applications in entertainment, education, interactive news etc. The VoD application enables the viewer to select his favorite video from a list of videos, & watch it at will. The VoD system is designed to provide access to a large archive of multimedia documents. VoD is an Internet service with a growing appeal to the mass market & is of increasing importance to Internet service provider's...
