Title:	AN EMPIRICAL STUDY ON ARCHITECTURE, CHALLENGES, TAXONOMY FOR ENTERPRISE APPLICATION MODERNIZATION
Author:	RAVIKUMAR RAMADOSS, ELANGO N.M, SIDDHARTH KASHIRAMKA
Abstract:	In the era of digital space, the enterprise applications should be accessible from mobile and different channels like SMS, IVR, email and other smart devices. Modernizing traditional existing applications to meet the demand of the increasing enterprise growth requires major shift in the focus of adopting modern technologies. Enterprise are looking for most cost effective way of modernizing their existing portfolio of application and subsequently looking for reducing the enterprise costs. Cloud and big data adoption is the must for any enterprise to do business insight modeling and by keeping their enterprise innovation strategy at par with their competitors. In order to mitigate the risk involved and to improve on the Return on Investment (ROI) it needs a systematic approach and methodology to mitigate the key risks and challenges involved. The modernization strategy should not be big bang and it should be a phase wise approach and should bring out all the relevance aspects upfront so that the modernization can be planned systematically to avoid any risk at later point. We propose a unique generic approach in doing the enterprise modernization and discuss about the key challenges, risks involved and also proposing a consolidated taxonomy for reference. The proposed approach will act as a generic methodology to perform the enterprise modernization across industry verticals.

Title:	VEHICLES CLASSIFICATION BASED ON DIFFERENT COMBINATION OF FEATURE EXTRACTION ALGORITHM WITH NEURAL NETWORK (NN) USING FORWARD SCATTERING RADAR (FSR)
Author:	NUR FADHILAH ABDULLAH, NUR EMILEEN ABD RASHID, ISMAIL MUSIRIN, ZUHANI ISMAIL KHAN
Abstract:	Feature extraction process plays an important role in classifying radar target. The extracted features will be fed as the input to the classifier. The incorrect choice of extracted features will cause poor performance of radar classification system. This paper presents the vehicles classification based on combination of different feature extraction algorithm with neural network using forward scattering radar. Hence, the main objective of this paper is to analyze the most suitable feature extraction algorithm which based on different dimensionality reduction technique in order to evaluate the performance of classification system. Three different techniques are used such as the manual and automatic reduction technique (PCA and Z-score) and neural network as classifier to classify the vehicles into their groups either medium or large based on their physical size. The performance of the classification system is determined by the percentage of classification accuracy. The higher percentage of the classification accuracy shows the better performance of the classification system.

Title:	A COMPARATIVE STUDY ON THE TIME LAG EFFECT OF INVESTMENTS IN INNOVATIVE INFORMATION SYSTEMS
Author:	Gyoo Gun Lim, Dae Chul Lee, Robert E. Cole
Abstract:	The IT productivity paradox is a phenomenon in which productivity doesn’t increase proportionally to IT investments. This discrepancy might be a result of the lag associated with learning and adjusting to a new technology. Information systems investment performance improves only after members or users learn and adapt to it. Nevertheless, many existing performance evaluation models cannot draw clear conclusions because they do not consider the time lag. This time lag can cause many problems such as a reduction in investments, change in informatization plan, or eventually failure of its implementation. Therefore, we propose a performance evaluation framework considering performance layers and time lags. We classify time lags into VTL (vertical time lags) and HTL (horizontal time lags) and classify existing indicators into the two categories. We identified time lags from the vertical perspective such as input, process, and output layers and also time lags in each layer from the horizontal perspective. These time lags might differ slightly across countries, and the type of system. A comparative study showed that there was a three-year HTL for WORKNET in Korea, and VTLs of one year for valve companies and one year for Amazon.com in the U.S.

Author:	USMAN AHMAD, DR. MD ASRI BIN NGADI, DR. ISMAIL FAUZI BIN ISNIN
Abstract:	Most of the traffic on the Internet is depend upon the Transmission Control Protocol (TCP), so the performance of TCP is directly related to Internet. Many TCP variants are developed and modified according to the environment and communication needs. Most of current TCP variants have set of algorithms which control the congestion in critical situations and maintain the throughput and efficiency of network. Now a day’s TCP is facing fast growth of Internet with the demands of faster data communication techniques on high speed links. In last 15 years many computer systems and cellular networks become linked together with protocol stack used in TCP. TCP variants with different congestion control techniques are working in different operating systems but a very small number of techniques are able to minimize the congestion in the network. This paper presents a survey on end-to-end congestion control techniques used in different TCP versions. The main purpose of this study is to review the characteristics and behavior of TCP variants with different techniques to control the congestion in the different network scenarios.

Title:	ELLIPTICAL CURVE CRYPTOGRAPHY ALGORITHM FOR SECURE MOBILE ADHOC NETWORK
Author:	A.VINODH KUMAR, DR.S.KAJA MOHIDEEN
Abstract:	Reducing network traffic and achieving high security are the most significant task of the Mobile Ad-hoc network (MANET). The beacon-less kNN query processing methods are utilized for reducing traffic and maintaining high accuracy of the query result in MANET. The explosion method and spiral method are adopted in this approach. However, the k-nearest neighbor (kNN) query processing in wired networks and wireless sensor networks cannot be applied in MANET due to the movement of mobile nodes and moderate network security. Hence, to overcome the drawbacks of the kNN query processing technique, this paper proposes the Elliptical Curve Cryptography Algorithm to improve the security in the Mobile Adhoc Network. Clustering approach also provides a mechanism to assign node duty cycles, such that a minimal set of nodes are active to maintain the network connectivity. The proposed approach includes topology discovery, dynamic cluster maintenance and cluster path switching, to enhance the energy efficiency of the network. The data security is monitored and maintained using the Elliptical Curve Cryptography Algorithm. The Quality of Service is enhanced, to improve the network performance. Experimental results show that the proposed algorithm can reduce the delay and achieve high security, when compared with the existing methods.

Author:	KARTHIGHA BALAMURUGAN, NIRMALA DEVI M., JAYAKUMAR M
Abstract:	Short-channel devices are preferred for realizing millimetre circuits, but these are affected by the short-channel effects (SCE). Multi-Gate (MG) MOSFET is found to be an alternative to overcome this drawback. In this paper, study and analysis of DC and AC parameters of MG MOSFETs have been attempted and small signal gain (y21) of multi-gate structure is analytically derived. Design of low noise amplifier (LNA) at 60 GHz using the channel charging resistance model has been done.Small signal gain and noise figure using the channel charging resistance model has been derived and analysed. The proposed LNA circuit uses various multi-gate MOSFET structures and the results are compared with conventional MOSFET based design. The designed LNA using a Quadruple Gate structure exhibited the noise figure improvement of 24.4% and 42.79% when operated at 1 V and 1.5 V respectively. Also the corresponding gain increases by 2.38 times and 4.9 times compared with conventional single gate MOSFET design.

Title:	A STUDY ON USER PERCEPTION AND AWARENESS RELATED TO ONLINE PRIVACY DURING ONLINE SHOPPING
Author:	RAMAKRISHNAN RAMAN, DHANYA PRAMOD
Abstract:	There is an unprecedented growth in the number of people buying products online. Online shopping is a fast growing phenomenon in India. Indian youngsters are not only buying and selling shares online, but also buying electronic gadgets, books, air tickets, footwear and clothing. Even vegetables and groceries are being purchased online. While many Indians are certainly concerned about their privacy and would never want anyone to eavesdrop, more often they do not take precautionary measures to protect their privacy during online shopping. Many web-retailers and e-commerce portals mention about their privacy policy, but it is always in fine print on the home page and the link for the same is kept at a place which is not prominently seen by user when he or she lands on their webpage for shopping. When a person goes with online shopping he or she gives several information including personal information like name, credit card number, mobile number, age, mail address, email address etc. This makes it necessary to understand if users are aware of the privacy issues and privacy policies of the web-retailers and e-commerce portals. This study attempts to understand, if youngsters in the age group of 20 to 30 years, who shop online are aware of the privacy issues associated with online shopping, and also understand the user’s perception on online privacy during their online shopping experience. The study explores to find if there is a significant difference in the perception of online privacy during online shopping between youngsters who are Information Technology (IT) graduates and others from non-IT education background and also between genders.

Title:	CRAMER RAO BOUNDS FOR PRIMARY USER LOCALIZATION USING HYBRID TOA/DOA TECHNIQUE IN COGNITIVE RADIOS
Author:	C.S.PREETHAM, Dr. M SIVA GANGA PRASAD, A.SUSMITHA, S.PRASANTH, M.R.KISHORE, A.ESWAR
Abstract:	Cognitive Radio (CR) is of great interest to technologists because of significantly increasing the spectrum efficiency. The Secondary user (SU) which is the unlicensed user must constantly study the actions of Primary user (PU), which is the licensed user. The location information of PU can enable several key functions of CR networks, such as aiding spectrum policy enforcement, intelligent location aware routing, and better spatial temporal sensing. Time of Arrival, Directions of Arrival and Received Signal Strength are three categories of research that is being done previously in the field of passive localization. These categories are done based on how the sensors obtain location estimation and on the type of measurements shared between the sensors. Cramer-rao bound establishes the lower limit on how much information about an unknown probability distribution parameter can a set of measurement carries. In this paper we obtain the Cramer-rao bounds for a novel hybrid Direction of arrival (DOA)/Time of arrival (TOA) based algorithm in cognitive radios networks and the performance is analyzed and compared for various primary user location estimation techniques such as RSS-CRB, Joint-CRB optimal, and Joint-CRB music.

Abstract:	Vehicular Ad hoc Network (VANET)is a kind of mobile Ad Hoc networks (MANETs)that is applied for progress of intelligent transportation system (ITS).Vehicles get various types of data from road-side units (RSUs)including voice, video and emergency data. Since the number of vehicles as well as the number and size of files are potentially large and with regard to the types of files can be various, QOS-based scheduling is a challenge. We inquire the scheduling algorithm problems of file distribution from RSUs to vehicles in an urban environment and propose a new scheduling scheme which considers the types of data and improved the performance of network. Request of vehicles are inserted in to 4 queues: 1) Data-queue 2) voice-queue 3) video-queue 4) emergency-queue. Some scheduling policies are used to choose one queue and serve the vehicles. Furthermore, we gave high priority to some requests such as video and emergency data to achieve high quality. In this regard, Simulation results indicate that the proposed approach provides required performance and quality of service.

Author:	Omar Fouad Mohammed, Burairah Hussin, Abd Samad Hasan Basari
Abstract:	Wireless sensors networking is a promising technology for a wide range of useful applications in many areas including civilian and military areas. Thanks to the sensing capabilities of Wireless Sensor Networks (WSNs), they become a prominent choice for certain applications such as environmental monitoring. The distributed sensors collectively realize the evolution of physical and operational phenomenon and predict its effect on mission execution and then trigger control actions that perform high-level mission procedures. However, efficiency, reliability and performance are the main challenges in deploying and utilizing WSNs especially in harsh environments conditions. This paper studies, the event tracking issues and identifies the reasons behind the deficiency of reliable transfer of the data traffic under abnormal situations or scenarios where WSN characteristics and performance may differ significantly. It investigates the performance issues related to routing protocols in WSN such as Low-Energy Adaptation Clustering Hierarchy (LEACH) and Directed Diffusion by using a simulation model in which represents a variety of sensor networking environments and examine their suitability for the WSN environment in terms of data traffic control. It was found that LEACH routing protocol outperforms Directed Diffusion due to its hierarchical nature, but suffers from several issues such as scalability, adaptability, utilization, latency, and throughput.
