In service oriented computing, services are the basic construct that aims to facilitate building of business application in a more flexible and interoperable manner for enterprise collaboration. To satisfy the needs of clients and to adapt to changing needs, service composition is performed to compose the various capabilities of available services. With the(More)

In the rapid development of internet technologies, search engines play a vital role in information retrieval. To provide efficient search engine to the user, Link Based Search Engine for information retrieval using K-Means clustering algorithm has been developed. The traditional search engines provide users with a set of non-classified web pages to their(More)
Vehicular Ad-hoc Network has become an active area of research which provides mobile communication among vehicles on road. It has tremendous potential to improve passenger safety on road, traffic efficiency, convenience as well as comfort for both drivers and passengers. It also delivers several other applications such as internet connectivity, smart(More)
A Vehicular Ad hoc NETwork (VANET) is a type of mobile Peer-To-Peer wireless network that allows providing communication among nearby vehicles and between vehicles and nearby fixed roadside equipment. The lack of centralized infrastructure, high node mobility and increasing number of vehicles in VANETs result in several problems discussed in this paper,(More)
Block Truncation Coding (BTC) is a fast moment preserving lossy image compression technique. This paper proposes a two-level compression scheme. In the first level of compression, the blocks are categorized into high-detail blocks and low-detail blocks. The high detail blocks are stored or transmitted in the form of a bit plane (16 bits), and two(More)
Vector Quantization (VQ) is one of the Lossy Image Compression Techniques. Vector Quantization is performed in three phases: 1.CodeBook Generation, 2.Image Encoding and 3.Image Decoding. In this paper, we have proposed a novel idea of incorporating the technique of Interpolation as part of the existing codebook generation technique to further reduce the(More)
Wireless sensor networks (WSNs) are used in many data-intensive applications. Although, it faces the problem to send all the data sensed by the sensor nodes to the base station within an application's lifetime due to the limited power supplies. Several mobile nodes like data mules, robotics and mobile base station were used for minimizing energy(More)
It is natural to represent an object by its parts and there has been strong evidence for part-based representations in human vision, Part-based representations allow for recognition that is robust in the presence of occlusion, movement, deletion, or growth of portions of an object. In the task of forming high-level object-centered models from low level(More)
Image Compression is the application of Data Compression on digital image. The techniques used for the image compression are broadly divided into lossy and lossless compression techniques. One of the lossless compression techniques is Huffman encoding. In this paper, the new method MH Encoding (Median Filter + Huffman Encoding) is used to compress the(More)
