SELF-MANAGING PERFORMANCE IN APPLICATION SERVERS – MODELLING AND DATA ARCHITECTURE
Get PDFHigh performance is always a desired objective in computing systems. Managing performance through manual intervention is a well-known and obvious mechanism. The attempts to self-manage performance with minimal human intervention are predominant in the recent advances of research. Control Systems theory is playing a significant role in building such intelligent and autonomic computing systems. We are investigating in building Intelligent Application Servers by enabling control system as a first class feature in component software, at design time and runtime. In this direction, it is important to build efficient data access mechanisms that capture the control system models, performance data, analyze the data efficiently, identify patterns and build a knowledge base. In this paper we propose a data organization and architecture as a building block of developing Intelligent Application Servers
E-GOVERNANCE PRIVACY POLICY, TECHNICAL AND SOCIAL CONCERNS OF PRIVACY IN E-GOVERNANCE FOR INDIA
Get PDFWith the introduction of E-Governance, ambient intelligence and ICT applications affect all areas of citizen lives. The field of justice is presenting opportunities and risks that, if mastered now, may offer a route and solution to the dilemma of privacy and scope of encountering it by properly positioning the jurisdiction with better resolutions. Law must be better enforced and more consistently applied across the member states to retain and sustain public credibility, trust and respect by properly safeguarding citizen interests denudes them of government authority especially in a largest democratic country like India. Privacy in cyberspace has been a continuing congressional priority as ICT is becoming pervasive through the implementation of e-governance. There is a need for having privacy law explicitly to India especially within the scope of EGovernance. Discussions are taking place to in the form of proposing it. So this paper while eliciting some of the privacy concerns, suggests that ASCP model can help as an initial level driving index to position the privacy and hence expected to be considered as a prologue to Privacy policy design
COMPREHENSIVE APPROACH FOR BILINGUAL MACHINE TRANSLATION
Get PDFMachine Translation has been a major focus of the NLP group since 1999, the principal focus of the Natural Language Processing group is to build a machine translation system that automatically learns translation mappings from bilingual corpora. This paper explores a novel approach for phrase based machine translation from English to Kannada and Kannada to English. The source text is analyzed then simple sentences are translated using the rules and the complex sentences are split into simple sentences later translation is performed
NOVEL DEFENCE MECHANISM AGAINST ON DEMAND ADHOC ROUTING PROTOCOL FOR MOBILE ADHOC NETWORKS
Get PDFTo access multimedia data mobile users like to use their own consumer electronic devices anywhere and at anytime . Hence, we expect that wireless ad hoc networks will be widely used in the near future since these networks form the topology with low cost on the fly. However, consumer electronic devices generally operate on limited battery power and therefore are vulnerable to security threats like data flooding attacks. The data flooding attack causes Denial of Service (DoS) attacks by flooding many data packets. However, there are a few existing defense systems against data flooding attacks. Moreover, the existing schemes may not guarantee the Quality of Service (QoS) of burst traffic since multimedia data are usually burst. Therefore, we propose a novel defense mechanism against data flooding attacks with the aim of enhancing the throughput. The simulation results show that the proposed scheme enhances the throughput of burst traffic

Get PDFWith the recent capability of being applicable in enormous fields, the Wireless Sensor Networks (WSN) have drawn attention of researchers and industries in diverse areas. Being deployed in areas that are hostile, WSN pose lots of difficulties and challenges to the research fraternity. In this paper, we discuss a generalized security framework for real world application of WSN. In particular we have considered the scenario of civil engineering field, a road tunnel. The proposed work mainly focus on security model for self adaptive lighting Model for road tunnel in WSN, and hence called Smart tunnel which provide the safety of the tunnels
OPTIMAL PLACEMENT OF PHASOR MEASUREMENT UNITS FOR POWER SYSTEM OBSERVABILITY WITHOUT CONSIDERING ZERO INJECTION BUSES
Get PDFThis paper present a method to find minimum number of phasor measurement units (PMUs) for complete observability of power system network for normal operating conditions.A linear algorithm is used to determine the minimum number of PMUs needed to make the system observable without considering zero injection buses. For state estimation and fault diagnosis in power system synchronized snapshot of whole system must be necessary. The proposed method is used to benchmark the optimal PMUs placement solution for the IEEE 14-bus, IEEE 18-bus, IEEE 24-bus, IEEE 30-bus and IEEE 57-bus test systems
HAKI-NFC BASED ANDROID APPLICATION
Get PDFNews forms of interaction should be considered if we want to model intelligent environments. NFC stands for Near Field Communication. NFC is a relatively new wireless technology and is gaining popularity. Its short range is the reason for its success. Operating over only short distance gives a large degree of security. The concept of NFC near field communication is that the technology is able to provide a very easy method of providing connectivity between devices that are a few centimeters apart, and without the need for all the security and set-up procedures that are needed for many other communication technologies. Thus applications using NFC will be really intuitive to use. Mobile devices have started integrating NFC capabilities into them. Nokia 6131 was the first handset to be introduced which included NFC capability. Now with increasing popularity of NFC, Android included its support for NFC with its 2.3.3 version. The major focus of this paper is developing android application(HAKI) based on NFC such as Smartposters, Attendance monitoring and helping visually impaired which targets wide range of audience
Quality of Service Based Handover Approach in a WLAN network
Get PDFAs the technology is improving so are the demands of end users and their applications increasing. A wide variety of new applications are being invented daily. These applications have different demands from the underlying network protocol suite. High bandwidth internet connectivity has become a basic requirement to the success of almost all of these areas. For the following concern Wireless networks have recently received a lot of attention. The most promising issue that needs to be taken into account while considering a wireless network is Quality of service (QoS). In this paper work we have considered a handover mechanism for IEEE 802.11 Wi-Fi and perform some modifications in that like firstly we increased the range of the access point and secondly increases the speed of Mobile Node (MN) and then study the effect of these changes on QoS in respective throughput delay and jitter. For the simulation purpose we have make use of wireless simulator NS-2 (Network Simulator version 2). Thus aim of this paper is to study the variations in average throughput, delay and jitter with the increased range of access point and increasing speed of mobile node with the help of NS-2 software
Route Request Flooding Attack Using Trust based Security Scheme in Manet
Get PDFIn recent years, the use of mobile ad hoc networks (MANETs) has been widespread in many applications, including some mission critical applications, and as such security has become one of the major concerns in MANETs. A mobile ad hoc network is set up with a group of mobile wireless nodes without the use of any dedicated routers or base stations. Each node acts as an end node as well as a router for other nodes. A Mobile Ad-hoc Network (MANET) is based on self organizing, dynamic structure and freedom of mobility idea. The characteristics like dynamic structure, limited power, restricted bandwidth and continuously changing network routes makes MANET more vulnerable to the attacks and providing the security to it proves to be a challenging area.In this paper,we describe that how the flooding attack occur and the effect of flooding attack. Finally, we present simulation results to show the detrimental effects of Flooding Attack
Performance Comparison of IACO,AODV Networking Routing Protocols
