Title:	MOBILE SINK BASED RELIABLE AND ENERGY EFFICIENT DATA GATHERING TECHNIQUE FOR WSN
Author:	P. MADHUMATHY, D. SIVAKUMAR
Abstract:	In wireless sensor network (WSN), data gathering causes more energy consumption. Also most of the existing literature work on data gathering process considers only distance and node density and skips reliability criteria. Hence in order to offer both reliability and energy efficiency, in this paper, we propose to design a Mobile Sink Based Reliable and Energy Efficient Data Gathering technique for WSN. In this process, a biased random walk method is used to determine the next position of the sink. Then, a rendezvous point selection with splitting tree technique is used to find the optimal data transmission path. When the data is sensed and ready for transmission, the sensor node encodes the data and communicates it to the sink. On receiving the encoded data from the sensors, the mobile sink decodes the messages and stores the resulting block in its local buffer. Once all blocks have been correctly decoded, the mobile sink reconstructs the original bundle. The increased packet losses in a specific region of the network can be prevented by increasing the pause time of the sink. By simulation results, we show that the proposed technique increases the reliability and energy efficiency.

Author:	NURIL KUSUMAWARDANI SOEPRAPTO PUTRI, HUDIARTO, ARGOGALIH, HANDI MULJOREDJO
Abstract:	Defined as the use of eco-friendly system and information technology, green Information Technology (IT) has been adopted in most world class universities worldwide. Meanwhile, DKI Jakarta as the capital city of Indonesia has a total of 325 private higher education institutions. Green IT term is quiet well known in these areas, although its implementation is still sporadic. However, information technology (IT) gives fully support toward the learning process at the campus area. As its project scope, this research was focused in DKI Jakarta, but it is applicable for others. Many research on green IT or green computing have been conducted, however none of them focusing on Private Higher Education Institutions in Indonesia. Based on the previous research done by various Private Higher Education Institutions,IBM and Green Computing Methodology by GTYS , the Green IT Governance Model for Private Higher Education Institutions in DKI Jakarta area was developed. However, further researches are expected in order to develop the best practice. Furthermore, energy saving, waste management systems and information technology will be controlled accordingly and the threat of toxins that can harm our health can be avoided.

Author:	MOHAMMAD ARIF SOBHAN BHUIYAN, MASTURA BINTI OMAR, MAMUN BIN IBNE REAZ, KHAIRUN NISA MINHAD, FAZIDA HANIM HASHIM
Abstract:	Fully integrated CMOS band-pass filter is a prerequisite of all modern transceivers. The filters are expected to encompass very low power dissipation, relatively higher Q-factor with proper centre frequency tuning. But there is some trade off among the parameters. Conventional band-pass filters suffer from some inevitable drawbacks which are not prominent in CMOS Gm-C configuration. In this paper, a review on the advancement of Gm-C filter circuits, illustrated in different literatures, is discussed with their merits and demerits. This review will serve as a comparative studies and reference for the researchers in designing future high performance band-pass filters for wireless transceiver frontend applications.

Title:	EVALUATION OF MOST USER BAND (MUB) ATTACK IN A COGNITIVE RADIO NETWORK BASED ON SUB-NYQUIST SAMPLING
Author:	R.SABITHA, Dr.K.R.SHANKAR KUMAR, CHRISTO REEGAN RAJ.V, RAMYA BHARANI.G
Abstract:	The unused or under-utilized TV bands are opportunistically utilized by Cognitive Radio enabled IEEE 802.22 Wireless Regional Area Networks(WRAN). However due to the nature of cognitive radio networks and lack of proactive security protocols, the IEEE 802.22 networks are vulnerable to various Denial of Service (DoS) threats. In this paper the target band for DoS attack is a specific band called as Most User Band which has maximum number of users among the available sub bands in the CR network. We propose a countermeasure strategy (Time concealment strategy), to counter the MUB attack. Simulation results are provided to demonstrate the effectiveness of the proposed MUB attack and TCS with attack time control for further survival improvement of secondary nodes.

Author:	ADAMU ABUBAKAR, SHEHU JABAKA, BELLO IDRITH TIJJANI, AKRAM ZEKI, 4HARUNA CHIROMA, MOHAMMED JODA USMAN, SHAKIRAT RAJI, MURNI MAHMUD
Abstract:	RSA cryptosystem is an information security algorithm used for encrypting and decrypting of digital data in order to protect the content of the data and to ensure its privacy. Prior research studies have shown that RSA algorithm is very successful in protecting enterprises commercial services and systems as well as web servers and browsers to secure web traffic. In an email application, it's utilized to ensure the privacy and authenticity of email message. Some studies have also shown the efficiency of RSA algorithm in securing remote login sessions, and electronic credit-card payment systems. Generally RSA algorithm gain a security support because of it’s frequently use in most applications where security of digital data is mostly a concern. Its strength lies with its ability of withstanding many forms of attacks. While many studies focus on proving that RSA algorithm is breakable under certain cryptanalytic attacks, yet there are some confrontations on the circumstances of applying those attacks. This paper presents the issues and challenges on some key aspects of cryptanalytic attacks on RSA algorithm. The paper also explores the perceived vulnerabilities of implementing RSA algorithm which can render a cryptanalyst easier means of attack.

Author:	MR.S. MUNI RATHNAM, Dr.T.RAMASHRI
Abstract:	Remote Sensing is vital because of their pressing need due to the analysis of natural hazards. Among the various natural hazards, the Volcanoes are terrific hazard which may harm the nature as well as the living things. Due to the aforesaid reasons, the identification of volcanoes and their hotspot identification are important to protect the living things. A mechanism which will be utilized to identify the volcanoes and their hotspot from the satellite images is proposed. Initially, the color space of the satellite image will be converted to another color space to identify the contents of the image clearly. After this process, the image will be segmented to identify the volcano’s hotspot. In order to identify the hotspot of volcano, the Artificial Neural Network (ANN) is utilized which uses Standard Back Propagation (SBP) Algorithm. The proposed mechanism will be developed with the aid of the platform MATLAB (version 7.11).

Title:	GAME-THEORETIC NASH-EQUILIBRIUM AND ECMDP-RANKING POLICIES FOR VERTICAL HANDOVER DECISION WITH EMERGENCY BRAKING IN VANETS
Author:	P. VETRIVELAN, S.SIVA MAHARAJAN, AND P. NARAYANASAMY
Abstract:	A Vehicular Ad-hoc Networks (VANETs) is a technology that uses moving vehicles as nodes in a network to create a mobile network. Vehicular communications like V-2-V and V-2-I with vertical handover decision process has to consider the speed limits and other real-time constraints such as lane-changes, emergency braking along with QoS parameters such as bandwidth, delay, jitter, bit error rate and cost. The proposed handover mechanism uses a game-theoretic Bayesian Nash-equilibrium based algorithm to select the network indicated by the Nash-Equilibrium point and uses a Extended Constrained MDP (Markov Decision Process) based algorithm with speed constraints in case of a tie between the networks.

Title:	A FLEXIBLE WEB SERVICE ENVIRONMENT WITH HIGH RANGE OF SECURITY AND QoS MECHANISMS
Author:	CHAKARAVARTHI.S , SELVAMANI.K
Abstract:	Providing information with Quality of Service (QoS) through Web services is essential to QoS-aware service management and composition. Delivering QoS on the Internet is a critical and significant challenge due to its dynamic and unpredictable nature. Even though the UDDI registry has all the details of WSDL documents provided by the service provider, it does not suggest the client to have a service with QoS parameters. In this proposed model, the UDDI extension is suggest to provide the Quality of Service information the customers. Moreover, the user affords the self encrypted data (privacy preserving) to the requester agent. The requester agent again encrypts the data by providing and considering the important QoS requirement for security. With the process of privacy preserving, the HTTPI protocol having the more secure capability like HTTPs. Thus the property of the HTTPs is integrated with HTTPI protocol and satisfies the QoS requirements for mechanisms, such as authentication, authorization, integrity and confidentiality in various level like Application level, Message Level and Transport level. QoS also covers non functional characteristics like performance (throughput), response time, security, reliability and capacity. This paper also analysis with non functional QoS parameters. Experimental results shows that our proposed work has excellent throughput, good response time and reply size in various configurations.

Title:	AN INDOOR-OUTDOOR POSITIONING SYSTEM BASED ON THE COMBINATION OF GPS AND UWB SENSORS
Author:	ABDELGHANI BELAKBIR, MUSTAPHA AMGHAR, NAWAL SBITI
Abstract:	Today localization techniques are gaining popularity because of the high interest for many business cases as well as for emergency/security scenarios including real-time tracking, navigation, clock synchronization … The need to obtain a precise position in a short time at any point, leads to use an efficient navigation system. In outdoor environments, GNSS (GPS, Galileo,...) is used and provide a good accuracy, but in the indoor environments, GNSS signal is deteriorated due to the signal degradation by different obstacles, so other techniques are used to locate users such as IR, RF, Cellular network or GNSS repeater. This paper provides a new design of Indoor-Outdoor positioning system based on the combination of data from UWB and GPS sources.

Abstract:	Magnetic resonance imaging (MRI) brain tumor segmentation is a challenging tasks which include the detection task of tumor from images. In general, this process is done manually by experts in medical images field which is always unclear, because the similarity between normal and abnormal tissues. The present study proposes a new clustering approach based on the hybridization of firefly algorithm (FA) and fuzzy c-means algorithm(FCM) called (FFCM) to segment MRI brain images. this approach use the capability of firefly search to find optimal initial cluster centres for the FCM and thus improve (MRI) brain tumor segmentation. The proposed approach was evaluated by applying it to a magnetic resonance imaging (MRI) brain segmentation problem using a simulated brain data set of McGill University and real MRI images from Internet Brain Segmentation Repository benchmark data sets. The cluster validity index (Rm) was used as a fitness function to determine the best solutions obtained by the firefly algorithm. The experiments indicated encouraging results after applying FFCM, compared with the outcomes of state-of-the-art segmentation algorithms and FCM random initialization of cluster centres.

Title:	APPLICATION OF NEURAL NETWORK TRAINED WITH META-HEURISTIC ALGORITHMS ON FAULT DIAGNOSIS OF MULTI-LEVEL INVERTER
Author:	M.SIVAKUMAR, R.M.S.PARVATHI
Abstract:	Growing industrial need makes the choice of fast response, accurate and efficient systems. The Multilevel inverter based induction drives (MLID) are the best solution for the industrial drive needs, which reduces the harmonics and increases the efficiency of the system. And also the need for hybrid electric vehicles increases the need of an efficient traction system with the use of multilevel inverters. As multilevel inverter has many semi-conductor switches, it is difficult to identify the fault in it. In this paper a new fault diagnosis method by using the total harmonic distortion (THD) of the voltage waveform and to classify the fault, neural network (NN) trained with back propagation, genetic algorithm (GA) and also with particle swarm optimization (PSO) is applied and the results are compared. Results shows that NN trained with PSO gives fast response in training algorithm when compared to BP and GA. Here a cascaded multi-level inverter based three-phase induction motor drive is taken as the test system. Mat-lab software is used to analyse the effectiveness of the test system and results are tabulated.

Author:	AHMED AL-JANAD, ROSLI OMAR, M. RASHEED, Z. IBRAHIM, M. H. A. MUSTAPHA
Abstract:	The aim of this research project is to analyze and design of energy storages in electrical distribution system. The proposed energy storages consist of super-capacitor and battery based on MATLAB/SIMULINK software environment. These two types of energy storages is implemented to two level voltage source inverters (VSI). The controller d-q reference frame technique is used and applied to the two level inverters. In order to avoid high frequency ripple from inverters output, low pass filter is investigated. The various performances of simulation results between super-capacitor and battery have been investigated. The Total Harmonic Distortion (THDv) of the inverter output voltage is measured where two types of energy storages (battery and super capacitor) are applied to the inverter input. It can be observed that the THD voltage and current at load for the super capacitor is considerably lower than the battery.

Title:	WATER CYCLE ALGORITHM FOR ATTRIBUTE REDUCTION PROBLEMS IN ROUGH SET THEORY
Author:	AHMED JABBAR, SUHAILA ZAINUDIN
Abstract:	The attribute reduction is known as the procedure for decreasing the number of features in an information system and its action is a vital phase of data mining processing. In the attribute reduction process, the least subset of attributes is selected (according to rough set theory which is employed as a mathematical tool) from the initial set of attributes with very little loss in information. In this study, a new optimization approach, known as the water cycle algorithm (WCA), has been used for attribute reduction and the rough set theory is employed as a mathematical tool to assess quality of solutions that are produced. The idea of the WC as an optimization algorithm was derived from nature, after examining the whole water cycle process which involves the flow of streams and rivers into the sea in the natural world. The WC-RSAR has been employed in public datasets that are obtainable in UCI. From the findings of the experiments, it has been shown that the suggested method performs equally well or even better than other methods of attribute selection.

Title:	DESIGN OF A UWB WIRELESS INDOOR RAKE RECEIVER USING CONTINUOUS AND DISCRETE WAVELET TRANSFORM APPROACHES
Author:	RASHID A. FAYADH, F. MALEK, HILAL A. FADHIL, SAMEER K. SALIH, FARRAH SALWANI ABDULLAH
Abstract:	In this paper, four levels of analysis and synthesis filter banks are proposed to create, coefficients for a continuous wavelet transform (CWT), a discrete wavelet transform (DWT), and an inverse, discrete wavelet transform (IDWT). The main property of these wavelet transform schemes is their ability to construct the transmitted signal across a log-normal fading channel over additive, white Gaussian noise (AWGN). There are many applications of wavelet transforms in wireless communication systems, and we chose the design of rake receivers as a major application to mitigate interferences and reduce the noise. In this research, a new scheme of rake receivers was proposed to receive indoor, multi-path components (MPCs) for ultra-wideband (UWB) wireless communication systems. Rake receivers consist of a continuous wavelet rake (CWR) and a discrete wavelet rake (DWR), and they use huge bandwidth (7.5 GHz), as reported by the Federal Communications Commission (FCC). The indoor channel models chosen for analysis in this research were the line-of-sight (LOS) channel model (CM1 from 0 to 4 meters) and the non-line-of-sight (NLOS) channel model (CM3 from 4 to 10 meters). Two types of rake receiver were used in the simulation, i.e., partial-rake and selective-rake receivers with the maximal ratio combining (MRC) technique to capture the energy of the signal from the output of the rake’s fingers. In the simulation, the transmitted and received radiations are presented with UWB single-in, single-out (SISO) with Walsh matrix coding.

Title:	CLUSTERING OF HIGH DIMENSIONAL DATASET USING K-MAM (MAX-AVG-MIN) METHOD WITH PRINCIPAL COMPONENT ANALYSIS A HYBRID APPROACH
Author:	S.DHANABAL , DR.S.CHANDRAMATHI
Abstract:	Clustering the high-dimensional data set is one of the main issues in clustering analysis. Reducing the data from high-dimensional to a meaningful representation of low dimensional will increase the efficiency of clustering algorithms. The performance of K-means clustering algorithm is poor for high dimensions. Hence, to improve the efficiency, in this paper, we apply the efficient dimension reduction technique, Principal Component Analysis (PCA), to obtain possible uncorrelated variables, called Principal Components (PCs), from the original dataset. Then the reduced set is used to find the initial centroid using the k-means initialization method, k-MAM (Maximum-Average-Minimum) and then it is applied to K-Means clustering algorithm. The results are compared to k-means with PCA. The final results show that the k-MAM with PCA outperforms well in terms of accuracy and number of iterations compared to k-means, k-MAM and k-means with PCA for high dimensional data set.

Title:	A FUZZY NEURAL NETWORK AND MULTIPLE KERNEL FUZZY C-MEANS ALGORITHM FOR SECURED INTRUSION DETECTION SYSTEM
Author:	P.ANANTHI , P.BALASUBRAMANIE
Abstract:	An Intrusion Detection System (IDS) is a security layer used to detect constant intrusive behavior in information systems. Many intrusion detection systems have been proposed based on the various data mining approaches such as decision tree, clustering, etc. Although the intrusion detection system is efficient way to find the attacks in the system, existing ones have some disadvantages which affects the performance of the system. It is observed that Neural Networks improves the overall performance of the intrusion detection system when it is integrated with a clustering approach. This research work aims to improve the performance of the intrusion detection system through the application of Fuzzy Neural Network along with an efficient fuzzy clustering method. In this proposed approach, initially Multiple Kernel Fuzzy C-Means (MKFCM) technique is used to construct different training subsets. The performance of the fuzzy clustering approach is improved through MKFCM. Then, different FNN models are trained to formulate different base models according to the different training models. Then the final results are aggregated through fuzzy based approach. The performance of the proposed MKFCM-FNN approach is compared with other existing approaches.

Abstract:	In the industrial installations of microwave generators, the current single phase power supply uses a single-phase HV power transformer with magnetic shunts for each magnetron. Based on the encouraging results obtained from the modeling of a new generation of single-phase HV power supplies for industrial microwaves generators with N magnetrons, we performed a feasibility study for a new three-phase HV power supply with N magnetrons per phase. In this paper, we present an original conception of a new three-phase of HV power supply for microwaves generators with N magnetrons per phase (treated case N = 1). The modeling of this new generation of power supply for magnetrons passes obligatorily by modeling and dimensioning of its own new three-phase HV power transformer with shunts. This modeling of the new three-phase HV power supply of one magnetron by phase, consists to exploiting the model of new three-phase HV power transformer with shunts by MATLAB-SIMULINK code. This model, resulting from the diagram of the armored magnetic circuit tetrahedron type equivalent of this transformer with magnetic shunts, is a π quadruple model with saturable inductances able to translating the saturation phenomena. The electrical signals obtained (currents and voltages) are variable magnitude curves, periodic and non-sinusoidal dephased 2π / 3 between them. These signals have the same form as those of experimental of a cla ‘(ssical power supply containing one transformer by magnetron. That presents multiple advantages in terms of reducing weight, volume, electrical wiring and cost during the implementation and maintenance of such a new device.
