Title:	INTEGRATION OF MOBILE AND WEB APPLICATION: AN IMPLEMENTATION OF DIABETIC MANAGEMENT SYSTEM
Author:	M.A. JABAR, M.F. AZMI, F. SIDI
Abstract:	Rapid development and high mobile devices penetration around the globe has impacted wireless and flexibility usage that promotes usability of technology at anytime and anywhere. Wireless technology has turned out to be the major medium in communication. One of the best-known examples of wireless technology is the mobile phone that can help to create solutions faster and easier than earlier days. However, designing and implementing these types of information systems can be highly challenging and difficult as user interaction with such technologies will be continuous and pervasive. Therefore, we propose a solution on how to deliver and share information in an ubiquitous environment. A prototype of diabetes monitoring system that support both mobile and web platform were implemented and evaluated. An evaluation based on expert judgment technique was used to validate the prototype. This study has shown that integration with mobile and web to access information on the internet can be a paradigm to promote ubiquitous information access and sharing.

Title:	A SURVEY ON MITIGATING ATTACKS RELATED TO SHORTCOMINGS OF ANDROID PERMISSION FRAMEWORK
Author:	IMAN KASHEFI, MAZLEENA SALLEH
Abstract:	Today Smartphones are the closest user assistants since they offer a wide range of functionalities to users. Although there are many applications developed in the market which facilitate the day-to-day user activities and provide a comprehensive means to entertain users, the number of malicious applications which misuse the users’ personal data or overcharge them are increased accordingly. These applications are granted privileges legitimately while they may not use them in a proper way. The aim of this paper is to address attacks related to the shortcomings of Android permission framework, which further are categorize to attacks result from applications with excessive privileges, confused deputy, and collusion attacks. This work compares the ability of existing approaches in mitigating these attacks since any improvement in current mechanisms or proposing novel methods to impede these types of attacks would not be achieved unless a comprehensive study on the current approaches takes place.

Author:	HAIROL NIZAM MOHD SHAH, MOHD ZAMZURI AB RASHID, NUR MAISARAH MOHD SOBRAN, ROZILAWATI MOHD NOR, ZALINA KAMIS
Abstract:	This project related to develop and implementation of autonomous vision based mobile robot following human based on clothes color. There have two part are involve which is mobile robot platform and classification algorithms by color. The core of the classification of color are comprise into two process; offline and online. An offline process consists of the training of the static image, using deference input sources that depend on the application. An online process consists of the matching process and the result of the clothes color position. Then classification algorithm is applied to find the centroid of the human. This centroid is then compared with the center of the image to get the location of the human with respect to the camera, either at the left or right of the camera. If the human is not in the center of the camera view, then corrective measures is taken so that the human will be in the center of the camera view. Data for the centroid of human is shown through the Graphical User Interface (GUI). One of the unique advantages in this project, the detection of human by color only uses image processing that generated by the algorithms itself without additional sensor like sonar or IF sensor.

Title:	PREVENTION OF WORM HOLE AND BLACK HOLE ATTACKS IN SECURE VBOR FOR MOBILE AD HOC NETWORKS
Author:	T. PEER MEERA LABBAI, V. RAJAMANI
Abstract:	In Mobile ad hoc networks, security is the main among the challenges to be considered. There are various types of attacks such as passive attacks and active attacks. Active attacks are more harmful than passive attacks. Some of the active attacks are more dangerous in mobile ad hoc networks since there is no central authority in MANETs. Examples of these attacks are: Worm hole attack, Black hole attack and Distributed Denial of Service (DDoS) attack and etc., In this paper, Secure VBOR is taken as our base paper. In Secure VBOR, groups are formed based on the residual energy of the node. Then the keys are exchanged among the user inside the group. Gateway members are playing the main role in group formation and preventing these attacks.

Title:	SERVICE ORIENTED REAL-TIME BUFFER MANAGEMENT FOR QOS ON ADAPTIVE ROUTERS
Author:	SARAVANAN.K, R.M.SURESH
Abstract:	To increase the quality of service in adaptive routers, this paper proposes a service oriented buffer management algorithm. This paper use different buffers for different service packets and the buffer controller maintains the buffer size according to flow of incoming packets. The buffer controller increases or decreases the buffer size at each input and output port by monitoring the rate of incoming packets and the size of buffer is fixed based on a flow threshold which is dynamic one. The value of flow threshold is computed using dynamic flow approximation algorithm. The proposed system reduces the packet dropping rate and increases the throughput.

Title:	OPTIMIZING OF SVM FOR CT CLASSIFICATION
Author:	N.T.RENUKADEVI, Dr.P.THANGARAJ
Abstract:	An automated classification of Computerized tomography (CT) images method uses Coiflet wavelets to extract features as input for the classifiers. Support Vector Machine (SVM) module is used to classify the images into different classes. Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) are used to optimize the parameters C and gamma of the RBF kernel in SVM. Parameter selection is thought of as an optimization problem where search techniques are used to maximize SVM performance. The observed results are considerably better than the results achieved by employing Support Vector Machine.

Title:	A TEXT-BASED IMPLEMENTATION MODEL FOR REUSABLE ASPECT MODELS
Author:	ABID MEHMOOD, DAYANG N.A. JAWAWI
Abstract:	Model-Driven Engineering utilizes modeling to provide abstraction techniques in order to effectively manage the complexity inherent in software systems development for a problem domain. Further, it emphasizes the use of models as primary development artifacts, and encourages researchers and professionals to develop ways that can lead to obtaining executable systems from models. Reusable Aspect Models is a multi-view modeling approach, which combines existing aspect-oriented approaches to modeling class, sequence and state diagrams, into a single approach. These models can serve as an effective design notation to provide abstraction for a given domain. Moreover, these models may be used as input to a model-driven engineering process to obtaining an executable system, by transforming them into aspect-oriented code. However, when investigating different ways of transforming models into code, an important technical issue is to determine a formal (and semantically equivalent) computer-understandable, text-based implementation of the graphical model. Here, a text-based model for Reusable Aspect Models has been presented. To make sure that the text-based model captures all relevant concepts of the notation, a conceptual reference model for Reusable Aspect Models has been presented first, and later implemented through the use of XML schemas.

Title:	LEACH-EMMR: AN IMPROVED CLUSTER BASED MULTIHOP ROUTING ALGORITHM FOR VEHICLES MONITORING NETWORKS IN MWSN
Author:	R.U.ANITHA, Dr.P.KAMALAKKANNAN
Abstract:	Due to rapid increase of vehicle accessibility and usage, traffic and overcrowding on the highways will produce an unsafe and inefficient to drive the vehicle. Vehicle Monitoring Network (VMN) is a Mobile Wireless sensor network based real-time system, which collects, transmits, analyzes and process the Vehicle Monitoring parameters in a testing area. Even though sensor networks are primarily designed for monitoring and reporting events, they are application dependent. A single routing algorithm cannot be sufficient in energy efficiency for mobile sensor networks in all applications. The cluster based methods and energy saving approaches are plays an important role on designing network routing protocols for the VMN. Thus this paper proposes an enhanced description of LEACH-Mobile algorithm called LEACH-Enhanced Mobile by Multihop routing (LEACH-EMMR) algorithm for the VMN. Simulation results shows that the LEACH-EMMR can reduce the energy consumption of nodes, decrease the process of clustering and prolong the network lifetime in the VMN.

Title:	A JOINT DESIGN OF ROUTING AND RESOURCE ALLOCATION USING QOS MONITORING AGENT IN MOBILE AD-HOC NETWORKS
Author:	P. SENTHILNATHAN, C. KALAIARASAN
Abstract:	In MANETs, mobile nodes can join and leave or change their position inside the network, so its topology can change anytime in unpredictable ways. So maintaining the QoS for the resource allocation is crucial for MANETs. In this paper, we propose a joint design of routing and resource allocation using QoS monitoring agent in MANETs. In this joint design, depending on the bandwidth request, a QoS monitoring agent checks the available bandwidth and allocates the resources temporarily for the real-time flows. In case of QoS changes or route breakages, the monitoring agent sent a feedback to the source, which contains the estimated amount of resources to be reserved or the route failure information. The sender adaptively adjusts the reservations or data rate when there is a QoS change or selects another efficient route when there is a route or link failure. By simulation, we show that our proposed joint design framework improves the throughput and bandwidth utilization.

Title:	VLSI DESIGN OF EFFICIENT ARCHITECTURE IN RECURSIVE PSEUDO-EXHAUSTIVE TWO-PATTERN GENERATION
Author:	G. SUDHAGAR, Dr. S. SENTHIL KUMAR
Abstract:	The aim of built in self-test is to make the machine to test by itself. The best method among the built in self-test is pseudo exhaustive two pattern generation produces the output according to the input given with 16bit generator. The main drawback that occurs in this test pattern generation is maximum delay. It occurs in the carry generator module. In this paper, the method proposed with recursive pseudo exhaustive two pattern generator to reduce the delay is that mixing the block of carry generator and adder in order to minimize the delay that produced while in testing process. A method of approaching the testing problem at the chip level is to appropriate built-in self-test capacity that present inside a chip. In exhaustive testing number of test vector are more which is decreased in pseudo exhaustive testing. Built in self-Test pattern generators are commonly discerned into one-pattern and two-pattern generators.

Title:	HYBRID ANONYMOUS LOCATION-AIDED ROUTING PROTOCOL FOR PRIVACY PRESERVING AND AUTHENTICATION IN MANET
Author:	Y.V.S.SAI PRAGATHI, S.P. SETTY
Abstract:	In mobile ad hoc networks (MANETs), the existing anonymous routing protocols result in increased overhead as the network size increases. Also, increased delay and inaccuracies are caused when the nodes deployed in the network lags the topology information in prior. In order to overcome these issues, in this paper, we propose a Hybrid Anonymous Location-Aided Routing Protocol (HALARP) for MANETs. This technique utilizes both proactive and reactive mode of anonymous location based routing. The proactive method is applied for the nodes within the pre-defined radius and reactive method is applied for nodes outside the pre-defined radius. When the source wants to transmit the data to the destination, it is executed using suitable encryption technique in secured manner with the help of topology information. By simulation results, we show that the proposed technique offers minimized overhead and delay and increased accuracy.

Title:	PERFORMANCE COMPARISON OF DYNAMIC MULTICAST GROUPS BASED ON MOBILITY SPEED
Author:	USHA DEVI G, ANUSHA K, RAJYALAKSHMI GV
Abstract:	Mobile Ad-hoc Networks (MANETs) have group of mobile users over a shared medium that can also offer group communications. In group-oriented communications, multicasting plays an important role. The combination of multicast services with ad-hoc environment introduces new challenges towards security issues. Clustering is an effective technique for group communication. Cluster formation involves election of a node as cluster head and it controls other nodes in the newly formed cluster. The joining or association and leaving or dissociation of nodes to and from clusters disturbs the stability of the network topology. This paper analyses the effect of mobility in dynamic multicast clusters, in which nodes uses multicast ODMRP routing protocol to collect its neighbours to form clusters. Simulation results show the performance in terms of throughput and average end-end delay under various network conditions.

Title:	A PREDICTIVE TRUST MODEL FOR E-COMMERCE APPLICATIONS
Author:	USHA DEVI G, SUTANU NANDI , ANUSHA K, RAJYALAKSHMI GV
Abstract:	E-business systems are growing exponentially in present days. Trust is essential for e-business systems and it is a part of modern e-commerce system. In this paper, we proposed a new algorithm to predict the trust value which is a transaction based feedback of peers for e-commerce applications. Before interacting with an unknown peer, it is rational to doubt its trustworthiness. Therefore, it makes the new transaction more secure by enabling trust evaluation prior to interacting with an unknown peer. A peer to peer e–commerce needs reputation for the knowledge of other peers.

Title:	CHANNEL ESTIMATION OF MIMO-OFDM USING CUCKOO SEARCH ALGORITHM
Author:	K.VIDHYA, Dr.K.R.SHANKAR KUMAR
Abstract:	In wireless communication, Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) plays a major role because of its high transmission rate. Channel estimation and tracking have many different techniques available in OFDM systems. Among them, the most important techniques are least square (LS) and minimum mean square error (MMSE). In least square channel estimation method, the process is simple but the major drawback is it has very high mean square error. Whereas, the performance of MMSE is superior to LS in low SNR, but its main problem is it has high computational complexity. While comparing with LS and MMSE method individually, the combined LS and MMSE method using evolutionary programming can greatly reduce the error. If the error is reduced to a very low value, then an exact signal will be received. Thus, we propose a hybrid technique that includes cuckoo search algorithm performs the conventional LS and MMSE channel estimation followed by enabling a fine tuning on the obtained channel model. The result shows the performance of the proposed method is better than LS and MMSE method in all the mutation & crossover values and also in all the iterations computed. We illustrate the performance of OFDM systems using propose technique can be observed from the imitation and relative results.

Author:	ŞAZİYE YÜKSEL, NAİME TOZLU, ZEHRA GÜZEL ERGÜL
Abstract:	In this paper, we continue the study of soft generalized closed sets in a soft topological space introduced by Kannan [1]. Firstly, we give a representation of soft sets and soft topological spaces. Secondly, we investigate behavior relative to soft subspaces of soft generalized closed sets. We show that a soft generalized closed set in a soft compact (soft Lindelöf, soft countably compact) space is also soft compact. Then, we show that a soft compact set in a soft regular space is soft generalized closed and disjoint soft g-closed sets in a soft normal space generally cannot be separated by soft open sets. Finally, we investigate some properties of soft generalized open sets.

Title:	STUDY OF COMBINED WEB PRE-FETCHING WITH WEB CACHING BASED ON MACHINE LEARNING TECHNIQUE
Author:	K R BASKARAN, DR. C.KALAIARASAN, A SASI NACHIMUTHU
Abstract:	High bandwidth utilization, reduced load on the origin server, high access speed are possible by combining Web caching and pre-fetching techniques. Pre-fetching is the process of fetching few Web pages in advance which will be assumed to be needed by the user in near future and those pages are cached in the memory. Lots of work has been reported for caching and pre-fetching of Web pages in the literature. In this paper, pre-fetching using clustering technique is combined with SVM (Support Vector Machine) – LFU algorithm, a machine learning technique for Web proxy caching .By using real dataset it will be shown that the SVM technique will be better than clustering based pre-fetching technique using caching policy like LFU considering bandwidth utilization and access latency.

Author:	K. HARIHARAN, R. PARAMESHWARAN, C. MANIKANDAN, R. SATHIYAPRIYA, D. SABITHA, Dr. V. VAITHIYANATHAN
Abstract:	TUT concentrates on ease of allocating a group of Weapon to a group of Targets. The problem of allocating weapon to a set of targets is typical an optimization problem with the aim of increasing the probability of hitting all targets by the weapon using Ant Colony Optimization. TUT model is designed in such that it maximizes the probability of mapping a set of most defensive weapon against a set of most attacking targets, to cause maximum destruction. TUT model is designed, mainly for war scenario of weapon coordination, the problem statement can be formulated based on six types of limiting factor, containing all defence information of entry angle, intercept angle ,states potential , power , resource (i.e., weapon constraints), frequency allocation constraints, as an factor to the TUT model.To make it definite, we concentrate on a platform to work with TUT and TUR by sending information from TUT to TUR with certain allocated frequency and power level. To accomplish that a set of Weapon are chosen against a set of Targets for allocation based on Ant Colony Optimization. We initially started with ant colony algorithm and compare the results with branch & bound technique on that we found, than ACO algorithm the branch and bound performs well. This enhances the accuracy of weapon to hit allocated Target. This improves the performance of overall BMD.
