Abstract

A Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location. The more modern networks are bi-directional with controlling the activity of the sensors. The development of wireless sensor networks was motivated by military applications such as battlefield surveillance Networks are used in many industrial and civilian application areas including industrial process monitoring and control, machine health monitoring, environment and habitat monitoring, healthcare applications, home automation, and traffic control. The purpose of this paper is to provide a brief technical introduction to wireless sensor networks architecture with few applications and also about how multipath data transfer can help to guarantee receiving data.

Abstract

Bluetooth has become an extremely popular technology in Wireless Personal Area Networking (WPAN), and is being extensively used for wide range of applications in which the communicating devices are in range of each other, forming a piconet. On the other front, Mobile Ad-hoc Networks (MANet) are being envisioned to provide a self-configuring network of randomly moving nodes, which would assist each other in increasing the range of the network and giving rise to a whole new set of applications. But a MANet routing system using Bluetooth devices poses a lot of challenges and not sufficient research work is yet available in this regard. In this paper the key challenges involved in Mobile Ad-hoc Networks (MANet) over Bluetooth are analyzed. Also, the characteristics of the Bluetooth technology that can be adopted to address the challenges are described. In addition, a design approach for an efficient mobile ad-hoc routing algorithm for Bluetooth nodes is presented.

Abstract

It has become ubiquitous that VoIP technology has revolutionized the communication media at various spectra. This paper’s pivotal focus is on investigation of the impact of session initiation protocol and its future course of supporting applications at various communication related requirements. As we are aware that VoIP, an extensively used technology, is very popular and is used to transmit both data and voice packets over a single line at the lowest cost.[1]Likewise, VoATM provides synchronous transmission and is the fastest of all. VoFR is another technology gaining colossal importance in the frame relay networks and its combination with VoIP and ATM is being designed for mass usage. Hence, there is always a need to invent and explore these technologies so that the technology is delivered to all the users at a reasonable cost and the best possible service is provided.Thus, each technology is better than the other technology in some way or another. Along side protocols like RTP and SIP protocols are used for multimedia and session oriented applications respectively. This paper tries to give a complete investigation of SIP protocol.

Abstract

Efficient content based retrieval of image and video databases is an important emerging application due to rapid proliferation of image and digital video data on the internet and corporate intranets and exponential growth of video content in general. Text either embedded or superimposed within video frames is very useful for describing the semantic content of the frames, as it enables both keyword and free-text based search, automatic video logging, and video cataloging. Extracting text directly from video data becomes especially important when closed captioning or speech recognition is not available to generate textual transcripts of audio or when video footage that completely lacks audio needs to be automatically annotated and searched based on frame content.

Towards building a video query system, developed a scheme for automatically extracting text from digital image and videos for content annotation and robust text extract which can handle complex backgrounds in video frames, deal with different font sizes, font styles, and font appearances such as normal and inverse videos. The algorithm results in segmented characters from video frames that can be directly processed by an OCR system to produce ASCII text. Results from the experiments obtained from MPEG video streams demonstrate the good performance if our systems in terms of text identification accuracy and computational efficiency.

Abstract

With the rapid growth of the World Wide Web, the use of automated Web-mining techniques to discover useful and relevant information has become increasingly important. One challenging direction is towards Web usage mining, wherein one attempts to discover user navigation patterns of Web usage from Web access logs. Web usage mining is the process of mining web access logs or other user information, user browsing and access patterns on one or more web localities. Web usage mining provides the support for the web site design, providing personalization server and other business making decision, etc. Web mining applies the data mining, the artificial intelligence and so on to the web data and traces users visiting characteristics and then extracts the users using pattern. This article presents an interface for the user to interact dynamically with the dataset and trace the working of the algorithms such as Apriori algorithm and generalized sequential pattern analysis based on timestamp values.
