Wetlands are the transitional zones between permanently aquatic and dry terrestrial ecosystems. Wetland systems directly and indirectly support millions of people, providing goods and services to them. The use of remote sensing technology for the mapping, identification, inventory and classification of the wetlands has been a common application of satellite imagery. Remote sensing has provided a great mean to study various ecosystems of the earth including wetlands by providing cost and time effective data. For a country like India, with its vast biological and cultural diversity, a comprehensive use of remote sensing, GIS and other related technologies is of great use in their conservation.DOI: http://dx.doi.org/10.11591/ij-ict.v1i1.547

This paper presents the effective method for the whole view synthesizing of the large-scale object. This synthesizing method is developed based on the image registration approach. The foreground object is extracted from each image by color image processing. The information of the feature points of an object is obtained from a foreground image and establishing the correspondence among views. The translation and rotation parameters between two successive images are estimated by the computed camera calibration parameters. The second image is transformed by using these parameters and combine to first image. The integrated image is obtained by combining the overlapping parts of these images. A whole view of the large scale object is reconstructed image by applying the above process successively. Preliminary investigations with sampled images of a real scene have been done to confirm the effectiveness of the proposed method.DOI: http://dx.doi.org/10.11591/ij-ict.v1i1.597

In LTE-Advanced, orthogonal frequency division multiple access (OFDMA) has been selected as the multiple access scheme for downlink and single-carrier frequency division multiple access (SC-FDMA) for uplink. OFDM is an attractive modulation technique in a cellular environment to combat frequency selective fading channels with a relatively low- complexity receiver. However, OFDM requires an expensive and inherently inefficient power amplifier in the transmitter due to the high peak-to-average power ratio (PAPR) of the multicarrier signal. This paper, presents the main components of LTE-Advanced including the all the details of Uplink (SC-FDMA) and Downlink (OFDMA). Also this paper clarifies the main reasons of using SC-FDMA in uplink and using OFDMA in downlink only, in order to obtain flexible mobile communication technology.DOI: http://dx.doi.org/10.11591/ij-ict.v1i1.557

Extra features can increase computation time, and can impact the accuracy of the Intrusion Detection System. Feature selection improves classification by searching for the subset of features, which best classify the training data. This paper proposed approach uses Mutual Correlation for feature selection which reduces from 34 continuous attributes to 10 continuous attributes and Fuzzy Decision Tree for detection and diagnosis of attacks. Experimental results on the 10% KDD Cup 99 benchmark network intrusion detection dataset demonstrate that the proposed learning algorithm achieved high true positive rate (TPR) and significant reduce false positive rate (FP ).DOI: http://dx.doi.org/10.11591/ij-ict.v1i2.591

The aim of this paper is to measure the security and related verification method in requirements engineering (RE). There are a few existing approaches to measure RE performance like IEEE Software Requirements Specification (SRS) and Security Quality Requirements Engineering (SQUARE). However, these existing approaches have some limitations such as lack of flexibility and require long implementation period. In order to address these issues, this paper intends to propose a new set of tools. First is the Effective Security Check List (ESCL), which is a check list with security questions that should be considered for measuring security. Secondly, the Traceability Matrix(TM), which is a two dimensional matrix to measure security during RE. Thirdly, Requirement Engineering Assessment Document (READ), which is a tool containing all statistical information about security performance during RE.  The combination of presented approaches had been implemented in a case study. The outcome results are encouraging and illustrated integrated outcomes within existing RE model. The security level had also been properly measured.DOI: http://dx.doi.org/10.11591/ij-ict.v1i2.695

The evolution of mobile Broadband over the years has been phenomenal and worthy of attention by academics, researchers, the corporate world and users alike. From the days of the First Generation (1G) through the Third Generation (3G) communication systems, the evolution has continued and has been largely influenced by an ever increasing demand for improved services and greater capacity evident in higher data rates, wider and improved coverage, improved spectral efficiency and lower latency. In response to these demands and to address some of the loopholes of the 3G networks, the 3rd Generation Partnership defined the Long Term Evolution (LTE). LTE though an evolving technology is widely accepted due to its unprecedented promised performance. As the evolution continues, the design of the ‘LTE-Advanced’ is already in progress and has been tagged different names such as the ‘4G’ and ‘Beyond 3G’ (B3G). The main backbones behind these evolutions are technological developments in the underlying mobile radio technology such as multicarrier technology (majorly OFDMA), multiple-antenna technology (MIMO) and the application of packet-switching to the radio-interface through improvements in techniques like adaptive scheduling in both the frequency and spatial dimensions, link adaptation of modulation and code-rate and several modes of fast channel state reporting. This paper is set to present the multiple antenna technology and how it contributes to the delivery of the expectations of the wireless communication systems beyond 3GDOI: http://dx.doi.org/10.11591/ij-ict.v1i2.1482

The importance of measuring service quality perceived by customers is an issue since the service quality is a key to success in service oriented industry. The estimation of service quality should be carried out with suitable measurement scales according to the types of service provided. To the best of authors’ knowledge, there have been little discussion about the applications of interval-valued intuitionistic fuzzy sets- based evaluation in measuring service quality. This paper proposes an evaluation for service quality of five vehicle insurance companies using interval-valued intuitionistic fuzzy entropy measure. Linguistic data were collected from customers using a questionnaire. An averaged interval-valued intuitionistic fuzzy number is used to construct decision matrix.  Interval-valued intuitionistic fuzzy weighted averaging operator is used to aggregate the interval-valued intuitionistic fuzzy numbers for alternatives. It is found that PCF Insurance was evaluated as the best vehicle insurance company in providing service quality to customersDOI: http://dx.doi.org/10.11591/ij-ict.v2i1.1525

The Semantic Web is an extention of the current Web that will allow to find, share and combine information more easily. The meaning in the Semantic Web is mostly represented by Resource Description Framework (RDF). To harvest such power requires robust and scalable data repositories that can store RDF data. Most of the existing RDF storage techniques rely on relation model and relational database technologies for these tasks. The mis-match between the graph model of the RDF data and the rigid 2D tables of relational model jeopardizes the scalability of such repositories and frequently renders a repository inefficient for some types of data and queries. This paper proposed a system that can store RDF data in the XML repository and discuss the basic idea of conversion from RDF Schema to XML Schema and XPath queries for extract information from XML database.DOI: http://dx.doi.org/10.11591/ij-ict.v2i1.1503

One of the major difficulties in face recognition system is an in-depth pose verification problem. Face recognition is a broad area of research over the last 25 years. However, the field is highly unsolved, largely due to variations in pose, illumination and expression. In this paper, a Ternary based Angle Oriented Face Recognition algorithm is proposed. In this algorithm, the data is made into two clusters namely, Clock wise and Anti-clock wise rotations using Fuzzy method. The image is extracted using angle oriented DCT (Discrete Cosine Transform) that invokes certain normalization techniques. Face Matching is compared to the technique of k-means. Based on Image Recognition pattern, the reliability of clusters is studied using Nelson model. The experimental results are verified.DOI: http://dx.doi.org/10.11591/ij-ict.v2i1.1779

Ranking is the central problem for information retrieval (IR), and employing machine learning techniques to learn the ranking function is viewed as a promising approach to IR. In information retrieval, the users’ queries often vary a lot from one to another. In this paper we take into account the diversity of query type by clustering the queries. Instead of deriving a single function, this system attempt to develop several ranking functions based on the resulting query clusters in the sense that different queries of the same cluster should have similar characteristics in terms of ranking. Before the queries are clustered, query features are generated based on the average scores of its associated retrieved documents.  So, for each query cluster, there will be its associated ranking model. To rank the documents for a new query, the system first find the most suitable cluster for that query and produce the scoring results depend on that cluster. The effectiveness of the system will be tested on LETOR, publicly available benchmark dataset.DOI: http://dx.doi.org/10.11591/ij-ict.v2i1.1505

Knapsack problem is a problem that occurs when looking for optimal selection of objects that will be put into a container with limited space and capacity. On the issue of loading goods into the container, optimal selection of objects or items to be sent must fulfilled to minimize the total weight of the capacity or volume limits without exceeding the maximum capacity of containers that have been determined. The types of knapsack that has been discussed so far is only to maximize the use not to exceed the limits specified capacity so it cannot be applied to the problem. This study aims to develop a dynamic programming algorithm to solve the MinMax 0/1 knapsack, which is an extension of the 0/1 knapsack with minimal and maximal constrain.  The result study showed that application of the MinMax 0/1 knapsack is used to generate the optimal solution to the problem of loading system goods into the container to optimize container space available compared with the loading of goods by PT DFI.DOI: http://dx.doi.org/10.11591/ij-ict.v2i1.1299

This study examines consumer’s perception related to perceived risk while doing transaction in e-auction system. Previous researches found there are some features in e-auction system recognized unclarity features as they indicate having fraud or cheating. In the online auction environment, perception could be categorized in two types such as privacy and security. This study proposed a conceptual framework based on perceived risks from consumer’s investigation, associated directly with four cost features of e-auction system: payment method, auction fee, bidding fee and third party services that combined with four perceived risk components: performance risk, psychological risk, financial risk, and time risk. Researcher has developed a questionnaire for collecting data from consumer’s who has experience in using e-auction. Through statistical analysis using multiple regressions, this study found that payment method, auction fee, and bidding fee have a positive impact on perceived risk. However, third party services have a significant effect upon consumer perceived risk on financial risk but not significant effect to time risk. Furthermore, the online auction features is directly related to reducing consumers' risk perception. As a summary, online auction features associated with financial play a crucial role in reducing consumers' perceived risk in online auction transactions.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.2529

Hypoxia inducible factor (HIF) is the main protein in hypoxia pathway. The response of HIF to changes of oxygen pressure is regulated by 2 oxygen sensors, prolyl hydroxylase (PHD) and factor inhibiting HIF (FIH). Studies have shown that biochemical reactions at molecular level actually exhibit stochastic and random behaviors. Modeling biochemical reactions using purely deterministic method, therefore, ignore these characteristics. Hence, we use stochastic modeling using CTMC to model this regulation. Nevertheless, the use of pure CTMC on complex biochemical reaction networks, such as hypoxia, results in an infeasible computation time and typically requires very large memory. Therefore, we use a numerical hybrid method that combines pure CTMC and deterministic methods. The purpose is to reduce time complexity and to obtain a better accuracy than deterministic method. Using this model, we can observe that an increase of oxygen pressure results in a decrease in the amount of HIF and that oxygen sensor FIH only inhibits C-TAD activity. The model is also able to classify 84% genes that were observedDOI: http://dx.doi.org/10.11591/ij-ict.v2i2.3845

In a VANET, the network topology is constantly changing. In fact, it requires distributed self-organizing security systems. In this article, we propose a distributed self-organizing trust management system for vehicular ad-hoc networks (VANETs), given the disastrous consequences of acting on false information sent by the malicious peers in this context. Our application can verify the correctness of alert messages sent by other vehicles about road accident. We opted to apply ambient communication technology to provide a self-organized network. We introduce the concept of “ambient intelligent vehicle” that consists in integrating ambient intelligence features in VANET. Vehicles are considered as intelligent agents that communicate in an ambient environment. Such vehicles are able to control and to detect false warning based on trust management system depicted in this article. Vehicles are arranged into clusters in order to facilitate communication and to reduce overhead. We model how vehicle operate using UML state diagram.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.2980

In wireless communication systems (WCS), channel characteristics are random and unpredictable. The resultant effect of the randomness is the multipath effect that leads to multipath fading. Multipath fading is a major contributor to the unreliability of wireless communication links. In this paper, Multiple-Input, Multiple-Output (MIMO) schemes were investigated in mitigating the effect of signal fading. Space-time coded MIMO-OFDM was developed to enhance the performance of the WCS. The performance of the developed space-time coded MIMO-OFDM over both flat and frequency selective channels were compared with that of conventional WCS. The simulation results show that the space-time coded MIMO-OFDM considerably reduced the effect of multipath fading in WCS with improved bit error rate (BER) value.DOI: http://dx.doi.org/10.11591/ij-ict.v2i2.2014

Noting the problem of increasing airports congestion, it is crucial to obtain a practical and efficient scheduling for departure and landing. The problem of deciding how to land an aircraft on the airport involves assigning each aircraft to an appropriate runway, computing a landing sequence for each runway and scheduling the landing time for each aircraft. The objective was to achieve effective runway use. In this paper, a multiple runway case of the static Aircraft Landing Problem was considered. It was assumed that one of the runways is not available. A mixed integer formulation approach was proposed to deal with the problem. The approach of solving this problem was breaking down the main problem into several sub problems. To validate the model, eight test problems were extracted from the OR-Library and discussions made on their solutions.DOI: http://dx.doi.org/10.11591/ij-ict.v2i3.5284

Current internet is incompetent and inept for the current trends of communication. The architecture of current internet was drafted almost 40 years ago and it is unable to cop up the problems aroused in context of security, mobility, robustness, congested traffic and vice versa of this millennium. In this paper, publish–subscribe internet routing paradigm (PSIRP) a reengineered architecture of internet is comprehensively studied, which will resolve many of the problems faced by the internet today. Keeping in view the importance of information/data, the reengineered architecture of PSIRP proffers the information–centric communication instead of host–centric communication, in response to which many of the problems of current internet will be resolved automatically. As major portion of internet is publish/subscribe in nature so PSIRP can provide a flexible, efficient and powerful architecture for future internet network design.DOI: http://dx.doi.org/10.11591/ij-ict.v2i3.3562

To envision and evolve the Internet into the future, what required is a simple but a vital architectural modification which focuses on “What (the contents)” rather than “Where (the addresses)”, that the Internet users and the applications are more concern about. So the communication can be more in effect if the customers can simply identify that what content they want to have instead of from where the content can be possessed. To achieve this and also to make the system more efficient and effective, new internet architecture emerged which we baptized as “Named Data Networking” or simply “NDN” in which packets bring with it the hierarchical data names instead of carrying the source and destination address. In NDN when the customer needs some data, he sends the interest packet which carries the name, is first received by the router and the router then forwards it as per instructed by FIB and uphold the status of pending interest , in further which is used for guiding the retrieved data back to the customer. The main objectives behind developing this architecture are to bring the scalability, efficiency, security and robustness in the current internet state, facilitating the user choice and competition as well. In this paper an overview of different future internet architectural approaches are provided such as CCN, NetInf, PRISP and DONA. NDN as a brand new architectural design among them remains the leading focus and its altered architectural design as a source of fulfilling the above mentioned major issues and objectives.DOI: http://dx.doi.org/10.11591/ij-ict.v2i3.5122

The paper demonstrates design of helical antenna to achieve stable frequency response and impedance matching beyond C-band microwave frequency. An impedance matching cavity is developed for excitation of higher order modes along with the fundamental mode in the helical antenna. Triple frequency bands are resonated by loading the designed helical antenna inside the cavity and a dual band response is realized by introducing variation in feed pin height with an incremental offset of 0.1λ to the initial height which is taken as 0.2λ. The broadband gain for all the designs and a detail analysis of modes along the helical antenna loaded in rectangular cavity is reported. A highest measured bandwidth of 5.4 GHz and a peak gain of 10.65 dB is obtained. The antenna being compact and conformal in design may find its application for terrestrial, aerospace communication and personal wireless communication.DOI: http://dx.doi.org/10.11591/ij-ict.v2i3.4861

The traditional mobile communications business model was based on full ownership of network infrastructure. However, network infrastructure sharing has been a trend among mobile network operators. Sharing traditional mobile network infrastructure which were not designed originally for sharing has become prevalent in the face of stiff competition, regulatory requirement and declining revenues. This, despite the reduction in capital expenditure for operators, brings technical challenges with regards to network planning, optimization and expansion in multi-operator shared environments. This paper briefly introduces models of passive infrastructure sharing and their advantages, and investigates the technical challenges which are inherent to communications tower sharing. The effects of non-optimal antenna height on coverage and signal quality, as well as those of tower loading constraints on transmission link quality are investigated among others. Simulation results and on-site measurements confirm these challenges, which may increase the operation expenditure of mobile networks.Our findings challenge the current perception in both academia and industry that passive infrastructure sharing can only produce positive effects, and therefore call for further investigations on the financial benefits of infrastructure sharing.DOI: http://dx.doi.org/10.11591/ij-ict.v2i3.4553

Computer network traffic is computer activity information in a network which explains interconnection between communication processes. The complexity of network traffic itself depends on the number of communication models used. The utilization of classification analyzing of network incident traffic is one of utilization forms of network traffic. The accuracy of classification model itself depends heavily on the formation of data training. The usage of C4.5 method in the establishment of decision tree in data training toward network incident traffic is with the basis to see the efficiency of decision tree formation. Wireshark tool is used as network capture tool to perform data acquisition in the formation of data training.

The adaptive learning systems are changing the learning process as we know it. One of the advantages they have over the traditional ways of learning is the attempt to adapt to the learner's capabilities in order to deliver the knowledge as optimizing as possible. Even in such sophisticated implementations there are differences in the treatment of the adaptive learning. During the past years spent in research of different aspects of the adaptive learning, we made a distinction of our latest development phase as an advanced adaptive learning, having more specific approach to the problem from the phase where the problem of adaptive learning is treated as a general case. Considering the conditions of advanced adaptive learning rather than basic adaptive learning, the process of learning is different and closely related to the human learner. In order to demonstrate this key improvement, we presented a general learner model through its learning mechanism and its behavior in the adaptive learning environment together with the instantiation process. In this paper we present a new way of learning with learning environment instances, constructed by choosing different ways to obtain the knowledge for a target unit.

Internet changes the way people communicate with each other and also affects the business flow. Technology changes affect how people live and communicate with each other, but they themselves also transform and become more human like. The agent oriented programming and multi-agent systems are relatively new example technologies that manifest these changes in a multifacet way. The goal of this paper is to explore the possibilities one can obtain by combining multi agent systems with the emerging semantic web technologies. This powerful combination leads towards new types of complex system development. Using a case study example, together with a comparison with the traditional system design approach, the paper also discusess the possibilities of semantic agent platforms and their development and shows how developers can benefit from following the standards to agent development.

The integration of computer games in the primary school program is a challenging task which requires changes in the pedagogical approach and teaching practices. Since it is important to understand students, this study follows student-centered approach while evaluating different variables in computer game enhanced classes, which impact the overall students’ Quality of Experience (QoE). We involved a total of 114 students in several primary schools in Macedonia which participated in traditional and game-based learning environment. Students’ feedback was collected through surveys and the data set was analyzed with a path analysis model that illustrates relationships between relevant variables which influence students’ QoE in classes enhanced with computer games. We found that students’ motivation mostly influenced students’ QoE, which was also determined by the increased effectiveness and simplified way of learning. The research results correlated students’ QoE and learning outcomes during integration of computer games in primary schools, which were altogether increased against the traditional environment.

In this work, we propose a proxy-protected proxy multi-signature scheme based on EllipticCurve Digital Signature Algorithm (ECDSA), which aims at providing data authenticity,integrity, and non-repudiation to satisfy the basic properties of partial delegation proxy signaturedescribed by Mambo et al. as well as strong proxy signature properties defined byLee et. al. The proposed signing/verifying scheme combines the advantages of proxyprotectedsignature and multi-signature scheme. The security of the proposed schemes isbased on the difficulty of breaking the elliptic curve discrete logarithm problem (ECDLP).The scheme proposed is faster and secure than the multi-signature based on factoring ordiscrete logarithm problem (DLP). The final multi-signature of a message can be verifiedindividually for each signer or collectively for a subgroup or entire group as well. Finally,the proposed proxy-protected proxy multi-signature schemes can be used in E-commerceand E-government application, which can be implemented using low power and small processingdevices.

Nowadays, Innovation is known as an essential component of competitiveness, classified in different types in literature. For instance, on one hand it is classified based on OECD as product, process, marketing and organizational innovations and on the other hand as incremental, competence developing, market developing and radical ones based on the degree of internal and external newness. Also, innovation models have changed from “simple linear” to “networking interactions” and concepts such as ‘open innovation’ and ‘innovation network’ have become important to both academic and market society due to intensive global competition. Therefore, this paper tried to empirically study and analyze the types of innovation based on OECD regarding to other classification based on the degree of internal and external newness in a networking interaction. Thus, in order to empirically explore the relations between these two classifications, we used the data of last three years (2008-2011) of 50 companies from the network Pardis Technology Park (PTP) in Iran as a case study. The results showed that most of the innovations as product, marketing and organizational were new to the market. Also marketing and process innovations were more related to radical and incremental innovation respectively and less organizational innovations were incremental.
