Abstract: Software engineers and architects have been faced with the problem of IT system complexity for some years. The challenge to build highly complex IT systems, ensure that these systems meet the needs of increasingly complex business processes and do all this in a way that allows everything to adapt quickly to changing market condition coupled with rapid development in information technology has been a problem facing the development and building of workable and functional information systems. Research on this problem has been conducted and it was found to cause large cost of software development project, schedule overrun and outright software project failure. A novel architecture framework was developed as a tool for resolving and managing IT system complexity in the enterprise as the end objective. Comprehensive business system frameworks are necessary to capture the entire complexity of such systems. The framework provides the conceptual foundation necessary for building and managing the integral business system and all its components and also provides an integrated description of enterprise information systems that comprises of the back-end systems, front-end systems, management tools and communication system. The framework provides a detailed process of information system development and defines the necessary subsystems that make up the integrated enterprise information system.

Abstract: A Wireless Sensor Network(WSN) contains short range energy limited terminals/nodes in which multiple nodes participates one by one to transfer data from source node to Base station. Each node appends some amount of delay which degrades the network performance as the jittered behaviour of network may not be allowed in some applications. Again the faulty nature of tandem nodes may create some severe routing scenarios. Concept of Broad Area Sensor Network (BASN) incorporates a real time communication between sensor node and Base station, which helps to optimize the Quality of Service (QoS). Our goal is to do extensive simulation on performance analysis of such sensor networks and its optimization.

Keywords - WSN ,energy limited terminals, jitter, Quality of service(QoS)

Abstract: Sequential pattern mining (SPM) is an important data mining task of discovering time-related behaviours in sequence databases. Sequential pattern mining technology has been applied in many domains, like web-log analysis, the analyses of customer purchase behaviour, process analysis of scientific experiments, medical record analysis, etc. Increased application of sequential pattern mining requires a perfect understanding of the problem and a clear identification of the advantages and disadvantages of existing algorithms. SPM algorithms are broadly categorized into two basic approaches: Apriori based and Pattern growth. Most of the sequential pattern mining methods follow the Apriori based methods, which leads to too many scanning of database and very large amount of candidate sequences generation and testing, which decrease the performance of the algorithms. Pattern growth based methods solve all above problems and in addition, it works on projected database which minimize the search space. Paper reviews the existing SPM techniques, compares various SPM techniques theoretically and practically. It highlights performance evaluation of each of the techniques. Paper also highlights limitation of conventional objective measures and focused on interestingness measures. Finally, a discussion of the current research challenges and pointed out future research direction in the field of SPM.

Abstract: Man being social by nature cannot live in isolation. He feels being in company with other co-humans. So sometimes he wants to connect with himself and most of the other times he wishes to be connected with others at other places through one means or the other. Man's persistent desire to be connected with something, or with somebody at a distance sometimes even across the globe any times has paved a way to the numerous inventions like Radio, Television, Telephone, Mobile, Internet culminating in the wireless networks. The mobile Adhoc Network popularly called in recent times MANET's is a unique development in modern times. It has converted the whole world into a global village for peoples to exchange information and diffuse knowledge. In this paper on "MOBILE ADHOC INETWORKS" the writer makes an attempt to explain MANET's in terms of its definition, characteristics, routing, protocols, dynamic source routing and its characteristics etc.

Title : A Study on Optimization of Top-k Queries in Relational Databases
Country : India
Authors : Neha Singh, P.K. Pandey
: 10.9790/0661-01043840      logo

Abstract: Efficient execution of top-k queries is increasingly becoming a major challenge for relational database technology. Top-k query has emerged as a key requirement in modern application. In these applications, efficient and adaptive evaluation of top-k queries is an integral part of application semantics. In this paper we discuss a query optimization framework of top-k queries that fully integrates rank-join operators. Ranking queries produce results that are ordered on some computed score. A key property of top-k queries is that, users are interested only in the first k results and not in total ranking of all query results. This property directly impacts the optimization of top-k queries by optimizing for the first k results. Traditionally, most real world database systems offer the feature of first n row optimization

Abstract: Ad-hoc networks have mass of applications; though, a dynamic problem regarding their security aspects must be answered in order to realize these applications. Validating the source and ensuring the integrity of the message traffic become an essential constraint for the operation and management of the network. We focus on the security problem of protecting the network connectivity between nodes in ad-hoc network. New nodes start to contribute in the network as guests; they can only become full members with a network signed certificate after their authenticity has been warranted by some other members. In this paper we introduce routine of multicast Protocol for tired authentication between the multilevel of ad-hoc network. In this proposed protocol Central Authority with trilateral authentication for managing key authentication and certification process which leads to increase the security and reliability of the network.

Title : A Video Watermarking Scheme to Hinder Camcorder Piracy
Country : India
Authors : Aditya.J, HarinniyIlanchezhian, Anoop.M
: 10.9790/0661-01044650      logo

Abstract: A watermarking technique that hinders camcorder piracy in Theaters by implementing the playback control is set forth. In this technique we watermark a finite number of frames so that any acquiescent video player cannot play the video. The watermarking technique should be impervious to any kind of geometric alterations and it should be a lossless compression, which will prevent the re-recorded video to be played in any of the video players.The IWT is not only computationally faster and more memory-efficient but also more suitable in lossless data-compression applications. The IWT enables you to reconstruct an integer signal perfectly from the computed integer coefficients. This method is not only simple to implement but is also more efficient than the other proposed watermarking techniques..

Abstract: E-learning is a platform that provides materials online with the objective of improving the users' teaching and learning experience. The main objective of this paper is to provide security to users' passwords within the E-learning Password Management System (EPMS) in order to protect the database from hackers. The protection process is done by implementing a symmetric encryption algorithm named International Data Encryption Algorithm (IDEA) on the passwords. The algorithm will be improved by modifying the size of the same secret key that is used in both the encryption and decryption operations of the data. The proposed algorithm is known as Double-Secure IDEA.

Abstract:A new method for key generation using Data Encryption Standard (DES) is proposed in order to make it more secure for Online Examination System (OES). Privacy and security are crucial in an OES. Privacy represents the ability to maintain a personal space such that there is certain user control on what and how much of personal information can be shared with others. Security describes the level of data integrity and protection the system offers. There are two main factors that affect the student's privacy and security in an OES: exam score and impartiality. The exam score is encrypted before being saved in the database and can only be accessed by the respective authorized student. Impartiality is accomplished by using the proposed cryptography scheme that encrypts the student's identification before sending the paper to the examiner for grading.

Abstract: Mobile Ad-hoc Network (MANET) special characteristics is an inestimable addition to traditional networking technologies, and is presently under active research & development .MANET are basically peer-to-peer, multihop network which is a group of wireless mobile hosts forming a transient network that is having no fixed infrastructure. This paper encompasses the key studies carried out so far and describes all the parameters for simulation. In particular, draw comparisons among different routing protocols: Bellman-Ford, AODV, DSR, LAR1, WRP, FSR and ZRP based on the performance metrics like PDR, end-to-end delay and throughput. The study is carried out to investigate various statistics and highlights behavior of different routing protocols for several MAC layer protocols such as 802.11, CSMA, TSMA which gives rise to various performance issues using GloMoSim simulation environment. Finally, results show the unusual behavior when varying the number of nodes in the network layout and effects of switching among datalink models.
