Title:	SYMMETRIC CRYPTOGRAPHY KEYS MANAGEMENT FOR 6LOWPAN NETWORKS
Author:	ANASS RGHIOUI, RIAD ABDMEZIEM, SAID BOUCHKAREN, MOHAMED BOUHORMA
Abstract:	Thanks to the 6LoWPAN (IPv6 over Low power Wireless Personal Area Network) technology, each object will get the opportunity to obtain an IPv6 address and integrate the world of the Internet of Things. This provides the ability to collect and monitor data remotely. Objects are heterogeneous; they vary depending on their operation, their material resources, and their role: data server, data requester or both. They are deployed everywhere and the information communicated via the internet between two separate objects is not secure and is vulnerable to an eavesdropping or modification attacks. We must implement an end-to-end security system to protect exchanged data confidentiality and integrity. Efficient used systems are based on asymmetric cryptography, but since these objects are resource-constrained and low power energy, it is not practical to adopt such solutions. Thus, 6LoWPAN combines between two different networks: LoWPANs and IPv6, we need a solution that addresses the security of internal communications and those across the internet. Existing solutions address the security of each type of communication separately from each other, where we must implement multiple solutions to secure a single network, the thing that is not practical for networks with resource constraints. In this paper, we propose a hybrid solution suitable for 6LoWPAN networks, based on the use of a remote server for authentication and security keys management, which aim to secure inter-LoWPAN and end-to-end communications. Our simulations and performance analysis shows that our solution provides security, and it is efficient in computation, communication, and storage.

Title:	GENERIC ANALYSIS METAMODEL BASED ON SERVICE ORIENTED SOFTWARE DESIGN
Author:	NIK MARSYAHARIANI NIK DAUD, WAN M.N. WAN KADIR
Abstract:	Analyzing software in order to evaluate its quality attributes is not a foreign concept in software lifecycle. There are many methods that can be implemented to analyze software with some focusing on source code analysis and others concentrating on analyzing software artifacts from various phases such as design artifacts. Service oriented software is not excluded from this. As software that uses services as part of its functionalities, service oriented software designs represent more completed view of the software compared to other artifacts. This work focus on identifying elements from design artifacts that represent service oriented software structure and behavior based on standard modeling language for service oriented architecture. The elements are then represented in a generic metamodel that can be used to analyze the software. A case study will be used to show how design artifacts from selected standard modeling language, SoaML being mapped to model based on proposed metamodel.

Title:	THE EVALUATION OF OPERATIONAL PERFORMANCE OF SUPPLY CHAIN AT AUTOMOTIVE INDUSTRY
Author:	GHOLAMREZA GHOLAMPOUR, ABDUL RAHMAN BIN ABDUL RAHIM
Abstract:	Todays, Supply Chain Management is one of the most important and complex issues for automakers in the world. The main objectives of this research are to explore the factors to predict operational performance of the supply chain (OPSC) through survey and case study research in IRANKHODRO Company (IKCO). Based on the supply chain theories, previous studies and structural equation modeling operational performance of the supply chain was predicted by process innovation (PI) and partnership quality (PQ). In addition, the relationship between IT and OPSC was moderated by process innovation and the positive effect of IT on OPSC was rejected. A total numbers of 217 completed questionnaires were collected from IKCO. The reliability of data was evaluated by using SPSS to analyse Cronbach’s alpha, where all values of alpha were acceptable strongly. According to SEM, measurement and structural model were analyzed to evaluate validity and hypothesizes. The confirmatory factor analyses (CFA) were utilized based on the Maximum Likelihood (ML) to examine model. OPSC model was examined for the first time in the automotive industry, which as the research gap was concluded. This research contributes to focus on IT, PQ, PI and OPSC as theoretical, managerial and practical implications.

Title:	DETECTING SUSPICIOUS PROFILES USING TEXT ANALYSIS WITHIN SOCIAL MEDIA
Author:	SALIM ALAMI, OMAR EL BEQQALI
Abstract:	The exponential advancement in information and communication technology has fostered the emergence of new channels for online discussion and has also reduced distances between people. Unfortunately, malicious people take advantage of this technological achievement in the sense that they use it for illegal purposes. In social media, the users produce several and various formats of suspicious posts (text, image, video…) and exchange them online with other people. The data in most social media sites are stored in text format, so in this work we will focus only on text posts. Text mining is an effective way to add semantics aspect to this communication’s form presenting a significant research challenge. Similarity approach is used in text analysis to detect suspicious posts in social media. The evaluation of our proposed approach is done within real posts.

Title:	PARAMETER OPTIMIZATION OF PROPORTIONAL INTEGRAL CONTROLLER IN THREE-PHASE FOUR-WIRE GRID-CONNECTED INVERTER USING ANT COLONY OPTIMIZATION
Author:	SUSATYO HANDOKO, SASONGKO P. HADI, SUHARYANTO, EKA FIRMANSYAH
Abstract:	This paper presents the parameter optimization of proportional integral (PI) controller in four-leg inverter for DG application when installed in a three-phase four-wire distribution system. The inverter can be utilized as power converter to inject power generated from renewable source to the grid and as shunt active power filter to compensate load current harmonics, load reactive power demand, and current unbalance. To achieve those functions, a reference current needs to be determined. In this study, DC voltage regulator used PI controller to generate the peak value of reference grid current. Optimal tuning of PI gain was required to obtain the best performance of PI controller. An algorithm based on the ant colony optimization (ACO) method was used to optimize the PI parameters. The objective function of optimization was to minimize the integral time absolute error (ITAE) of dc-link voltage and average total harmonic distortion of grid currents (THDiave). The usefulness of the approach was demonstrated by a simulation.

Title:	UDFP-TREE: AN EFFICIENT TREE FOR INTERACTIVE MINING OF FREQUENT PATTERNS FROM UNCERTAIN DATA
Author:	MOHAMMAD H. NADIMI-SHAHRAKI, FATEMEH HABIBOLLAHI, HAMID RASTEGARI
Abstract:	An increasing number of efficient methods have been proposed to mine frequent patterns from uncertain data obtained from real applications such as social networks and life-sciences. Since these data are constantly being updated, needs of the users are changed and they adjust a new minimum support threshold to find new and proper frequent patterns. Obviously, finding the new frequent patterns by running the algorithm from scratch is very costly especially when the database is very large. In this paper, an efficient tree called UDFP-tree is proposed for interactive mining from uncertain data. The proposed tree aims to construct the mining model separated from the mining process. The experimental results show that by using UDFP-tree, there is no need to reconstruct the mining model when user changes the minimum support threshold.

Title:	A FULLY ASSOCIATIVE CACHE ARCHITECTURE
Author:	S.SUBHA
Abstract:	Fully associative caches expend maximum energy among caches for any size. The blocks of fully associative cache are searched in parallel during address mapping. This paper proposes architecture to reduce the power consumption in fully associative cache. The cache blocks are assumed to operate in one of two modes - on or off. The model consists of introducing one bit per block which is enabled on block occupancy. This bit is checked before the address match is performed. This saves power consumption in address comparison. The proposed model is simulated with SPEC2K benchmark. An improvement in power consumption of 59% with no change in average memory access time is observed for the chosen parameters.

Title:	USING MULTI-AGENTS SYSTEMS IN DISTRIBUTED DATA MINING: A SURVEY
Author:	AHMEDAMINE FARIZ, JAAFAR ABOUCHABAKA, NAJAT RAFALIA
Abstract:	Extract accurate information from huge databases about petabytes has an unprecedented utility. However, the implementation of a data mining system requires an enormous amount of work and an extremely long run time in some cases of distributed environments. Distributed Artificial Intelligence consists that the entities with certain amount of autonomy must have the capacities of perception and action on their environment, which brings us to the concept of "cooperative agents" and therefore multi-agent systems. These systems are becoming more and more essential in many application fields due to the fact that they can solve the problems of complexity and distribution, especially when it comes to large systems such as data mining. This document is an overview of the integration of multi-agent systems and distributed data mining known as MADM (Multi Agent-based Distributed Data Mining).

Title:	NEW TECHNIQUE FOR DUPLICATION THE REMOTE DATABASES BASED ON MULTI-AGENTS
Author:	NOREDDINE GHERABI
Abstract:	Most enterprises use multiple sites to store remote data. Therefore, it is important to centralize the data in real time with efficient systems that duplicate the data to a central site. In this paper, I present a new approach to duplicate the data stored in multiple remote sites using multi-agents. These facilitate the transfer of data and schema of a database automatically and quickly, we exploit the communication between multiple agents to duplicate data and schema. A prototype has been developed using multiple mobile agents to extract the Relational-Object schema and corresponding data from a remote site, and then make a comparison with the schema from the central site to duplicate the data. The experimental results were highly significant, demonstrating that the proposed method is feasible and effective.

Title:	COMPARATIVE EVALUATION OF SERVICE INTERFACE APPROACHES TO SYSTEM INTEGRATION FOR OPERATION CENTER
Author:	NORZIANA YAHYA, ABDUL HANAN ABDULLAH
Abstract:	System integration of an operation center has become more complex and heterogeneous due to rapid innovations in the IT industry. Problems arise when a new integration requirement emerges due to complexity of the system integration architecture. To simplify the system integration, interoperability has to be emphasized at the design stage. Architectural design is the stage wherein the process to identify the interfaces involved in the system integration needs to be considered. Approaches to simplifying system integration via service interface design have been the subject of many research studies. In this paper, case study on two (2) traffic operation centers in Malaysia i.e. Transport Management Centre of Kuala Lumpur City Hall and Traffic Monitoring Centre of Malaysian Highway Authority were conducted to identify gaps amongst the system integration approaches used in both operation centers. Three (3) prominent approaches of system integration used by both operation centers were chosen, explored and discussed, namely, method-oriented interface, message-oriented interface and resource-oriented interface. The result of a systematic comparison of the approaches mentioned is also presented. Six (6) criteria were established to make comparison on the approaches: interoperability, uniformity, scalability, reusability, heterogeneity, and compatibility. The objective was to determine the best contemporary approach to service interface design in centralized system integration. The outcome of the evaluation was examined and improvement to the service interface design is proposed. The study is very significant as an attempt to establish a practice reference for enhancement of the current system integration as well as serve as a guide for future deployment of operation centers.

Title:	CENTROID DYNAMIC SINK LOCATION FOR CLUSTERED WIRELESS MOBILE SENSOR NETWORKS
Author:	MANAR A. MIZHER, SALEH H. AL-SHARAEH, MEI CHOO ANG, AYMAN M. ABDALLA, MANAL A. MIZHER
Abstract:	The wireless sensor network consists of three main components: a large number of small-sized sensors, a remote sink connected to the internet, and a cluster head whose existence depends on the overall network structure. The sensor in the wireless sensor network can be deployed through many ways, such as a simple model, a random walk model, and a random direction model. There were studies that examined networks and their various installation methods to save energy consumption and increase the network lifetime. These were usually achieved by formatting the network structure with one or multi-sinks, with or without clusters, or using static or mobile components such as sink, cluster heads, and sensors. In addition, using a homogeneous or heterogeneous environment implies using special devices as cluster heads or electing them from sensors periodically at specified times depending on different protocols. Previous studies did not focus on saving energy when all network's components were mobile. Our scheme, Centroid Dynamic Sink Location (CDSL), focuses on this case and aims to reduce the energy consumption through moving the sink to the optimal location with respect to the cluster heads. The simulation results indicated that the CDSL scheme increases the network lifetime by saving the cluster heads energy. When the sink is mobile, the network lifetime increased in all cases from 14.21% to 53.09% compared to that which use a fixed sink.
