Title:	INTELLIGENT SELF-TUNING PID CONTROLLER USING HYBRID IMPROVED PARTICLE SWARM OPTIMIZATION FOR ULTRASONIC MOTOR
Author:	ALRIJADJIS, TANAKA KANYA, NAKASHIMA SHOTA
Abstract:	Ultrasonic Motor (USM) is a new important actuator that has superior features than the common electromagnetic motor. But, due to no-accurate mathematical model and characteristic changes during operation, it is hard to control USM. In this paper, an Intelligent Self-tuning PID controller using Hybrid Improved Particle Swarm Optimization (HIPSO) for USM is presented. The proposed HIPSO is developed to improve PSO by using combination of three strategies, i.e., additional part for creating new sharing information, adaptive inertia weight for obtaining properly balance quickly and mutation operator for maintaining diversity within particles. Experimental results show that the proposed control scheme can greatly enhance the performance of USM servo system in term of convergence speed and position accuracy.

Title:	PROACTIVE ROUTING WITH EARLY CONGESTION DETECTION IN MANET
Author:	A. MOHAMMED MUNAWAR HUSSAIN, Dr. P. SHEIK ABDUL KHADER, Dr.A.MOHAMED ABBAS
Abstract:	Ad hoc mobile networks are composed of mobile nodes communicating through wireless medium, without any fixed backbone infrastructure. In these networks, congestion occurs in any intermediate node, when data packets travel from the source to the destination, and they incur high packet loss and long delay, which cause the performance degradation of a network. This paper proposes Proactive Routing with Early Congestion Detection (PRECD) in MANET. Initially PRECD constructs a non-congested neighbors’ list, and finds a route to a destination. All the primary path nodes periodically calculate their queue_status at the node level. While using the early congestion detection technique, the node detects the congestion that is likely to happen, and sends a warning message to the nodes. The ancestor node is aware of this situation, and finds an alternative path to the destination immediately, by applying adaptive path mechanism. Thus, PRECD improves the performance, in terms of reducing the delay, routing overhead, and increases the packet delivery ratio without incurring any significant additional cost. The performance of PRECD was compared with that of Early Congestion Detection and Adaptive Routing (EDAPR) and Early Detection Congestion and Control Routing (EDAODV), using the NS-2 simulator. The result reveals significant improvement over the EDAPR and EDAODV routing schemes.

Title:	CONGESTION PREDICTION IN WIRELESS NETWORK USING GENE EXPRESSION PROGRAMMING TECHNIQUE
Author:	Dr. S. KANAGA SUBA RAJA, C.VISWANATHAN, Dr.D.SIVAKUMAR, V. BALAJI
Abstract:	Congestion Control is very important in any network to provide a good quality of service. This paper implementing a Network based Congestion Control technique using Gene Expression Programming. Congestion is caused when the number of packets stored at the router buffer exceeds the total capacity of the buffer. Under this state the additional packets received at the router are lost. In any Network, the measured Buffer Utilization value can be used to identify congestion. Whenever congestion occurs there is a drastic loss of data packets. To overcome this problem this work tries to implement a method where the congestion is predicted before it occurs and to avoid it. To achieve this, here a summary of the past and present buffer utilization value and the corresponding parameters that determine the buffer utilization are collected and this information is used by the Gene Expression Program to predict the future buffer utilization value. This value is used to identify the occurrence of Congestion in the network in the near future. Once Congestion is predicted, less drastic measures can be taken to avoid it

Title:	A SURVEY ON SECURED SEARCHING TECHNIQUES FOR EFFECTIVE DATA UTILIZATION IN PUBLIC CLOUD
Author:	M.SHYAMALA DEVI, C.ARUN
Abstract:	Recent technology advances have made the success of cloud computing by acquiring the infrastructure, platform and software from the third party vendor. The promising benefit of cloud computing is data service outsourcing, by which the data owners stores their data in the public data centers by economically saving their capital investment towards data management. Cloud Storage provide users with abundant storage space and make user friendly for immediate acquiring of data, which is the foundation of all kinds of cloud applications. However, data outsourcing in the commercial public cloud also raise the problem for unauthorized data access and the cloud storage does not make sense if the outsourced data is not effectively utilized. The practical challenge is on how to make effective data access in the public cloud storage aiming at improvement of various searching techniques for increasing the data utilization. In this paper, an attempt is made to survey various searching techniques towards effective data utilization in cloud storage and is discussed in detail.

Title:	A NEW MODELING OF THE PEDESTRIANS EVACUATION IN PANIC SITUATIONS BASED ON VICSEK MODEL
Author:	KHALID ZINE-DINE, ABDELLAH MADANI
Abstract:	Nowadays, evacuation problem is critical since it is used in many applications. These applications include sites where masses of people gather such as sporting events, transportation centers, and concerts. A relevant objective is how to consider the mobility of pedestrians in a room in order to improve evacuation times. In this paper, we realistically simulate how human communication affects the behavior of individuals’ pedestrians using a modified Vicsek model. The considered modifications of the original model are achieved by introducing more features and parameters into the original model. The simulation results show that evacuation time is greatly affected by several factors, such as, number of pedestrians (density), the panic situation and the chance to find an appropriate exit and escape paths

Title:	A POWER AWARE TRANSMISSION SCHEME SELECTION WITH DATA AGGREGATION FOR WIRELESS SENSOR NETWORKS
Author:	I.S.AKILA , Dr.R.VENKATESAN
Abstract:	Many sensor applications today demand the need of extended lifetime. Among the most popular approaches which address this issue, Multiple Input Multiple Output (MIMO) and Single Input Single Output (SISO) techniques explore environment-specific performance constraints of achieving this target. Under a constant bit error rate, MIMO saves a considerable transmit power and then increases the lifetime. However, the increased overhead imposed on MIMO favors the choice of non-cooperative SISO in some sensor applications. To combine the merits of both of these approaches, this paper employs selection mechanism which suggests a suitable approach. A transmission scheme is modeled through a non-transferable coalition formation game which is destined towards prolonging network lifetime. Along with the existing scenario, we also ensure fairness of the power distribution using the centralized data-aggregation scheme in our proposed methodology. The simulation results demonstrate the improved performance of our approach in a Wireless Sensor Network application.

Author:	G.BALAJI, I.GNANAMBAL, M.ABINAYA
Abstract:	This paper proposes adaptive Maximum Power Point Tracking (MPPT) controller for Permanent Magnet Synchronous Generator (PMSG) wind turbine and direct power control for grid side inverter for transformer less integration of wind energy. PMSG wind turbine with two back to back voltage source converters are considered more efficient, used to make real and reactive power control. The optimal control strategy has introduced for integrated control of PMSG Maximum Power Extraction, DC link voltage control and grid voltage support controls. Simulation model using MATLAB Simulink has developed to investigate the performance of proposed control techniques for PMSG wind turbine steady and variable wind conditions. This paper shows that the direct driven grid connected PMSG system has excellent performances and confirms the feasibility of the proposed techniques. While the wind turbine market continues to be dominated by conventional gear-driven wind turbine systems, the direct drive is attracting attention. PM machines are more attractive and superior with higher efficiency and energy yield, higher reliability, and power-to-weight ratio compared with electricity-excited machines.

Title:	DESIGN OF STANDARDIZATION ENGINE FOR SEMANTIC WEB SERVICE SELECTION
Author:	S. MAHESWARI , G.R. KARPAGAM , S. MANASAA
Abstract:	Proliferation of web services opens the research arena of ontology based approach for selection of the appropriate web service(s) that satisfies the users’ requirements with high accuracy. Real world ontologies tend to be large as they contain thousands of concepts and several web services are associated with them; further, several services provide similar functionalities. In such a scenario, the discovery and selection of the suitable service(s) among the equivalent services, requires a standardized approach, emphasizing on both functional and non-functional aspects. This paper proposes a Standardized Engine that incorporates a layered approach. The first layer, lexicon search, performs semantic matching using word net; second layer Concepts based refiner, is responsible for comparing the concepts available in the domain ontology; the third layer, QoS (Quality of Service) based refiner, performs a statistical analysis using QoS parameters namely response time, throughput and availability. The evaluation of the standardized engine is performed using the metrics precision, recall and f-measure.

Abstract:	Text clustering methods have been discussed with various factors. We have the goal and problem of making decision with rationality factors about how much information is available or how complete the document about the knowledge. We propose a new rational text clustering algorithm using the semantic ontology. The documents are processed to extract the key terms as feature vectors. Semantic frequency SF and inverse semantic frequency ISF are computed for each document. Using computed SF and ISF we compute semantic weight for each document towards various categories, based on which the document is identified to a class or category.

Title:	DEVELOPMENT OF COVERAGE BASED CELL SELECTION ALGORITHM FOR WIMAX
Author:	P. KAVITHA, DR.R.UMA RANI
Abstract:	Fourth generation (4G) mobile systems focus on effortlessly incorporating the existing wireless technologies like GSM, wireless LAN, and Bluetooth. This contrasts with third generation (3G), which simply focuses on developing new standards and hardware. WiMAX have been rapidly emerging in the last few years. The mobile subscriber and traffic volume have been largely increased in WiMAX. During the stage of network planning, a cell capacity and size are typically fixed depends on the calculation of peak traffic load. Cell planning is one of the most basic problems in network design. In this paper, a development of Coverage Based Cell Selection (CBCS) algorithm for 4G is introduced. The proposed model utilizes the cell selection algorithm. The best coverage base station can be selected based on three criteria: i.e. demand, profit and capacities. The performance of the proposed CBCS algorithm is compared with the four existing approaches like greedy algorithm, Bounded Greedy Weighted Algorithm (BGWA), Call Admission Control (CAC) and Joint Scheduling & Resource Allocation (JSRA). The proposed CBCS algorithm results better network throughput and also provides better bandwidth consumption ratio than the existing approaches.

Title:	DISTRIBUTED AND SECURED DYNAMIC PSEUDO ID GENERATION FOR PRIVACY PRESERVATION IN VEHICULAR AD HOC NETWORKS
Author:	Y. BEVISH JINILA, K. KOMATHY
Abstract:	Safety applications in Vehicular Ad hoc Networks (VANET) needs to be handled with at most care such that no adversary will be allowed to intrude the privacy of the user. Replacement of original IDs with pseudo IDs makes this possible. Generating and storing a set a pseudo IDs by the trusted authority in the tamper proof device of each vehicle and changing them at fixed intervals paves way for an adversary to trace the original ID of the vehicle. And, the space required for storing all the generated pseudo IDs in the tamper proof device of each vehicle is huge. In this paper, we propose a novel approach where pseudo IDs are generated dynamically based on the location information when an event is to be reported and verified by the distributed Traffic Management System (TMS). If a safety message send by a vehicle is detected to be malicious by the TMS, the safety message is forwarded to the Trusted Authority (TA) to map the original ID for the corresponding pseudo ID. The mapped original ID is forwarded to the TMS to take necessary action. Since pseudo ID generation is based on the password provided for driver authentication, in addition a distributed password preservation method is introduced, which preserves the password even when a TA is compromised. Experimental analysis shows that this scheme provides better privacy and conditional traceability compared to existing approaches.

Author:	Z.KARTIT, H.KAMAL IDRISSI, A.KARTIT, M.EL MARRAKI
Abstract:	Security issues are becoming more critical in network systems. Firewalls offer an important defense and protection for network, permit to strengthen security aspect. Firewalls are network devices or programs which enforce an organization's security policy, permit to control and monitor the traffic flow of network; they are installed between networks or hosts that employ differing security postures. Generally firewalls were deployed at network perimeters in order to provide some measure of protection for internal hosts. Different firewalls support different policy editing commands. The set of policy editing commands that a firewall supports is called its policy editing language. In [1], the authors provide deployment algorithm for type II language. This paper aims to develop an efficient algorithm for the updates of the security policy. Our proposal is considered improved type II edition policies algorithm. Although the proposed algorithm in [1] gives correct results, but it has severe shortcomings of security in the implementation of the new policy of security, in addition, this algorithm has a high degree of complexity. We will propose an algorithm that will address these two weaknesses of the old algorithm, which allows us to gain in terms of security and complexity.

Title:	PERFORMANCE EVALUATION OF DYNAMIC SOURCE ROUTING UNDER BLACK HOLE ATTACK
Author:	RAJESHKUMAR.G, Dr.K.R.VALLUVAN
Abstract:	Mobile Ad hoc Network (MANET) is a network that does not have a fixed infrastructure and have the ability to manage its network independently. It consists of a collection of “peer” mobile nodes that are capable of communicating with each other. Nodes within each other's radio range, communicate directly via wireless links, while those that are far apart use other nodes as relays in a multi-hop routing fashion. Since mobile ad hoc networks make it possible for the devices to join or leave the domain without required permission, nodes in the domain cannot be completely trusted. This makes MANET susceptible to attacks from malicious nodes. In this work, the impact of black hole attack on MANET is evaluated. In this work, the impact of black hole attack on MANET is evaluated. Simulations were carried out using Dynamic Source Routing (DSR) for network without malicious nodes and with 10% malicious nodes. Simulation results show that the throughput degrades by 45.44 % and the end to end delay increases by 38.3 % due to the presence of malicious nodes in the network.

Title:	ERROR MINIMIZATION IN LOCALIZATION OF WIRELESS SENSOR NETWORKS USING DIFFERENTIAL EVOLUTION WITH MOBILE ANCHOR POSITIONING (DE - MAP) ALGORITHM
Author:	S.SIVAKUMAR, Dr.R.VENKATESAN
Abstract:	Sensor Node Localization is considered to be one of the most critical issues in a Wireless Sensor Network (WSN). The objective of localization is determination of physical co-ordinates of a group of sensor nodes. The location information plays a vital role for coverage, deployment of sensor nodes and rescue operations. Many applications such as routing and target tracking are all location dependent. This work aims at determining the location of the sensor nodes with high precision. The initial part of this work is carried out by localizing the nodes using Mobile Anchor Positioning (MAP), a range-free localization method. As the anchors move through the network, they broadcast their location as beacon packets. The sensor nodes use the location information of beacon packets obtained from mobile anchors as well as the location packets from neighbouring nodes to calculate their location. Our proposed algorithm used for Localization is Differential Evolution with Mobile Anchor Positioning (DE - MAP). We have incorporated DE – MAP algorithm over the results of MAP to enhance the location accuracy. The idea is to compare the performance of DE-MAP algorithm to Genetic Algorithm with Mobile Anchor Positioning (GA - MAP). Root Mean Square Error (RMSE) has been used as a performance measure to compare between the two approaches namely, DE-MAP and GA-MAP. Simulation results demonstrate the fact that our proposed Differential Evolution with Mobile Anchor Positioning (DE-MAP) algorithm is effective in bringing down the localization error when compared to GA-MAP algorithm.

This interest is expected to grow further with the proliferation of wireless sensor network applications. As localization is becoming popular, many attacks on the localization process are also on a rise. These attacks confuse the localization process and cause location estimation errors. Range based methods like received signal strength indication (RSSI) is affected a lot by physical attacks. This paper proposes a solution based on multi frequency multi power antenna to provide robust and accurate localization technique . In addition this paper proposes a grid coloring algorithm to detect the signal hole map in the network which is refer to the attack prone regions in order to take a corrective actions . The simulation results showed improvement in the localization accuracy in the presence of barrier attacks through detecting , filtering and eliminating the effect of these attacks.

Title:	PID CONTROLLER FOR NARX AND ANFIS MODELS OF MARINE PIPE CYLINDER UNDERGOES VORTEX INDUCED VIBRATION
Author:	MOHAMMED JAWAD MOHAMMED, INTAN Z. MAT DARUS
Abstract:	PID controller discrete time on marine cylinder pipe risers which represented based on system identification models under vortex induced vibration (VIV) has been verified in this work. Input-output data have been provided from the experimental setup of previous paper. Two System identification methods used to create models which are: Neural Network based on Nonlinear Auto-Regressive External (Exogenous) Input (NARX) and Adaptive Neuro-Fuzzy Inference System (ANFIS). NARX and ANFIS models have selected based on Mean Square Error (MSE) technique. While, PID controller has been applied to overcome on the pipe cylinder oscillation for all models. Also, the controller performance has been compared on each model during from tuning the controller parameter (KP, KI and KD) depending on the heuristic method and validation the gain values based on Mean Square Error (MSE) technique. Finally, the consequences demonstrated that the ANFIS model better than the NARX model to forecast the dynamic behavior of the system. By contrast, PID controller has been managed to decrease the pipe cylinder fluctuation for all models specially the NARX model system identification.

Title:	ARTIFICIAL BEE COLONY OPTIMIZATION FOR FEATURE SELECTION IN OPINION MINING
Author:	T. SUMATHI, S.KARTHIK, 3M.MARIKKANNAN
Abstract:	Opinion mining, a sub-discipline of information retrieval and computational linguistics concerns not with what a document is about, but with its expressed opinion. Feature selection is an important step in opinion mining, as customers express product opinions separately according to individual features. Earlier research on feature-based opinion mining had many drawbacks like selecting a feature considering only grammatical information or treating features with same meanings as different. However this led to a large corpus which subsequently affected the classification accuracy. Statistical techniques like Correlation Based Feature (CFS) have been extensively used for feature selection to reduce the corpus size. The selected features are sub optimal due to the Non Polynomial (NP) hard nature of the technique used. In this work, we propose Artificial Bee Colony (ABC) algorithm for optimization of feature subset. Naïve Bayes, Fuzzy Unordered Rule Induction Algorithm (FURIA) and Ripple Down Rule Learner (RIDOR) classifiers are used for classification. The proposed method is compared with features extracted based on Inverse Document Frequency (IDF). Hence, this method is useful for reducing feature subset size and computational complexity thereby increasing the classification accuracy.

Title:	ARIMA MODEL-BASED RTT ESTIMATION FOR CONGESTION AVOIDANCE MECHANISM IN ASYMMETRIC NETWORKS
Author:	JEYASEKAR A., KASMIR RAJA S.V., ANNIE UTHRA R
Abstract:	The delay-based congestion control mechanism performs well over the bandwidth-symmetric network rather than bandwidth-asymmetric network. The upstream and downstream link of asymmetric network has different bandwidth ie high bandwidth in the downstream link and low bandwidth in the upstream link. Therefore mostly the bottleneck link is the upstream link, not the downstream link. Therefore even if the downstream link of data flow is uncongested, congestion in the upstream link can disrupt the acknowledgement flow. Even if ACKs are smaller in size than data packets, the upstream link is unable to carry the high rate of ACKs. The congestion in the upstream link increases the round-trip-time of a packet and causes loss of ACKs. The increase in round-trip-time triggers the congestion avoidance mechanism and slows the window growth which reduces the throughput performance. Therefore we propose a congestion avoidance mechanism which uses RTT estimation based on Auto Regressive Integrated Moving Average model (ARIMA). It provides better performance than the delay-based TCP in the asymmetric network and also symmetric network. The simulation results show that the proposed congestion algorithm achieves 39% to 400% throughput improvement than the delay-based TCP.

Title:	AN OPTIMIZED QOS BASED COST EFFECTIVE RESOURCE SCHEDULING IN CLOUD
Author:	S.P.JENO LOVESUM, DR.K.KRISHNAMOORTHY, BLESSED PRINCE. P
Abstract:	Cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and consumers. Resource scheduling, which is a part of resource management is an important process that takes place in storage cloud which falls under IaaS cloud, so that the available resources may be properly allocated to the requesting tasks in a best fit manner so that no resources are wasted. As most of the scheduling techniques do not consider the minimum memory wastage in our work we have considered this factor as a QOS since most of the users of cloud resource are concerned about their cost and as memory usage plays a major role is calculating the cost we try to schedule the jobs among the available VMs so that minimum memory wastage is taken into account while allocating the VMs to complete the task. In this paper a QOS model for optimized task scheduling is used to minimize task completion time and task response time and minimum memory wastage. The task manager checks all the virtual machine and assigns the task to proper virtual machine which will have least memory wastage. Here the task is taken as storing a file in cloud storage. A QOS algorithm based on PSO is used to provide an optimal solution for resource scheduling. The simulation results show that the proposed method has the ability to find optimal trade-off solutions for task scheduling problems that represent the best possible compromises among the conflicting objectives.
