2012 2nd International Conference on Power and Energy Systems(ICPES 2012)

作者： Nainsi Gupta1 Mayank Gupta Rahul Agrawa M.Tech Student Dept. of Computer Science and Engineering M.Tech Student School of Mathematics and Computer and Applications Thapar University

The pen-based devices are not so common in India and one reason for that is the absence of localized applications. Developing an online handwriting recognition system for Gurmukhi scripts for such devices would play an important role in making these devices available and usable for the Indian society. Preprocessing will play an important role in increasing the accuracy of such online handwriting recognition system. A model for preprocessing a Gurmukhi stroke is proposed. This model consists of 5 basic algorithms for preprocessing. Prior to these algorithms, a basic step called Stroke Capturing is done, which samples data points along the trajectory of an input device (electronic pen or mouse) while the character is drawn.

In this paper, we outline observations made during projects in the field of innovative e-commerce information systems. Our first group of observations concentrates on the exploration of an innovative e-commerce idea. As it turns out, in the first phase of e-commerce information system development, an e-commerce idea should be developed into an e-commerce model, in which both business- and technical considerations play an important role, and on which stakeholders should agree. Moreover, stakeholders should be confident that the e-commerce idea is feasible from an economic perspective. Such a model then can be used to do a more detailed requirements engineering track. Our second group of observations concentrates on experiences with finding such a model. © 2012 Pillay Engineering College.

It is now feasible to host basic web services on a smart phone due to the advances in wireless devices and mobile communication technologies. The market capture of mobile web services also has increased significantly, in the past years. A few efforts have been taken to partitioning the web services. In this paper we propose a framework which separate complex and easy services depends workload in a distributed environment. The mobile device keeps the interface of web services. Mobile device going to be act as integration point between user and back end. Our contribution is an evaluation of compression techniques for use with web services in mobile networks. We have analyzed the proposed framework with some sample data. The experimental results have shown improved results by deploying the proposed framework.

ACO variants in solving Mobile Ad hoc Network routing

ACO variants in solving Mobile Ad hoc Network routing

International Conference on Emerging applications of Information Technology (EAIT)

作者： Debasmita Mukherjee Sriyankar Acharyya Dept. of Computer Applications Techno India EM4/1 Sector-V Salt Lake Kolkata India Dept. of Computer Science and Engineering West Bengal University of Technology Kolkata India

Mobile Ad hoc Network (MANET) is one of the most upcoming technologies in the field of wireless communication. As there is no predefined network configuration in MANET, routing, therefore, is much more difficult compared to that in a wired network. It is known that in MANET there is a continuous change in topology resulting in the change in adjacent nodes to a certain node. This subsequently may play a vital role in finding the path from source to the destination host. Meta-heuristics, like Ant Colony Optimization (ACO) are being used successfully in MANET routing. In our earlier work we made some variations of ACO techniques for routing in wired network. Here, in this paper, some modifications on those variants of ACO have been made considering the situations in MANET. Variations are related to selecting the next node to visit depending on the number of adjacent nodes to the current node and modification of the pheromone deposit formula on the basis of transmission time. In some variants a tabu list has been incorporated to enhance the performance remarkably. Using NS2 simulator the experiments have been made to compare the performance of six variants of ACO, where the various parameters have been adjusted optimally. It is observed that modified versions are better than the previous ACO variants in overall performance related to throughput and packet drop rate.

The ABC algorithm is a new meta-heuristic approach, having the advantages of memory, multi-characters, local search, and a solution improvement mechanism. It can be used to identify a high quality optimal solution and offer a balance between complexity and performance, thus optimizing forecasting effectiveness. This paper proposes an efficient prediction model for forecasting of short and long range stock market prices of two well know stock indices, S&P 500 and DJIA using a simple adaptive linear combiner (ALC), whose weights are trained using artificial bee colony (ABC) algorithm. The Model is simulated in terms of mean square error (MSE) and extensive simulation study reveals that the performance of the proposed model with the test input patterns is more efficient, accurate than the PSO and GA based trained models.

While most digital collections have limited forms of change - primarily creation and deletion of additional resources - there exists a class of digital collections that undergoes additional kinds of change. These collections are made up of resources that are distributed across the Internet and brought together into a collection via hyperlinking. Resources in these collections can be expected to change as time goes on. Part of the difficulty in maintaining these collections is determining if a changed page is still a valid member of the collection. Others have tried to address this problem by measuring change and defining a maximum allowed threshold of change, however, these methods treat all change as a potential problem and treat web content as a static document despite its intrinsically dynamic nature. Instead, we approach the significance of change on the web as a normal part of a web document's life-cycle and determine the difference between what a maintainer expects a page to do and what it actually does. In this work we evaluate the different options for extractors and analyzers in order to determine the best options from a suite of techniques. The evaluation used a human-generated ground-truth set of blog changes. The results of this work showed a statistically significant improvement over a range of traditional threshold techniques when applied to our collection of tagged blog changes. © 2012 ACM.

Network Coordinate Systems (NCS) allow accurate latency estimation with low measurement overhead. However, NCS are vulnerable to attacks, which makes security issue a crucial concern in their large-scale deployment. This paper proposes Sniper, a social relationship based defence mechanism for securing NCS. In contrast to prior proposals that allow attacks to occur and then detect them, Sniper can filter out potential malicious nodes before they mount attack. Extensive simulations demonstrate that Sniper can protect NCS against various forms of attacks efficiently and that Sniper can tolerate a large fraction of malicious nodes.

Advances in mobile networking and information processing technologies have triggered vehicular ad hoc networks (VANETs) for traffic safety and value-added applications. Most efforts have been made to address the security concerns while little work has been done to investigate security and privacy for value-added applications in VANETs. To fill this gap, we propose a value-added application, specifically, a security and privacy preserving location-based service (LBS) scheme for VANETs. For each LBS transaction, the scheme provides authentication, integrity and non-repudiation for both the service provider and the user. A user can obtain the service in an anonymous way and hence user privacy is well protected. However, a tracing procedure can be invoked to find malicious users, thereby efficiently preventing users from abusing the anonymity provided by the system. © Springer-Verlag Berlin Heidelberg 2012.

Wireless Mesh Networks (WMNs) do not rely on any centralized administration and they are built by the connection of various static and mobile entities (i.e. nodes). The cooperation and coordination between these network entities is very essential to establish a secure routing path. Such distributed nature of WMNs increases the vulnerability of routing protocols. Modeling and computing trust in such a distributed environment is essential since the network is self-organizing, self-configuring and relies on multihop routing. Therefore, to ensure a secure route discovery and its maintenance, it is important to compute trustworthiness of individual nodes in a cooperative manner for discovering neighbors, selecting routers and announcing topology information in WMNs. In order to detect trustworthy nodes in the networks, we propose a model based on Multiple Criteria Decision Making (MCDM) which quantifies node behaviors into discrete quantity. The proposed scheme ensures detection of malicious and misbehaving nodes in the network which is verified through code simulation. © 2011 IEEE.
