Even the most cutting-edge communication-mediated technology like satellite navigation for orbit positioning, pedestrian movement recognition systems based on inertial sensors, 5G systems, let alone medical devices for coordination of human organs functionality would not be invented without technologies for language processing as an information source between humans and communication systems. Regardless...
Fault Diagnosis is an essential management task for any telecommunication network and it is even more crucial for Wireless Sensor Networks due to their dynamic nature. Based on Agent Technology, this paper presents an architecture that combines different network and diagnosis models to carry out a Fault Diagnosis process: a Causal Model to relate fault root causes with their symptoms and a Structural...
In our century, human race gets older because the number of young people is less than the expected values. Thus, medical maintenance and treatment systems are getting more important. Besides, computer and transmission technologies improve consistently and they are utilized in many areas. For this reason, researchers contrive to benefit new technological improvements and instead of using old medical...
This paper considers the network energy efficiency in multi-cell OFDMA downlink systems. We propose a resource allocation scheme with limited coordination to optimize the network energy efficiency and satisfy user requirement. The proposed scheme has two steps; centralized and distributed. In the first step a central unit allocates the resources for cell- edge users at first place giving them high...
In this paper a novel and fast algorithm of transmit antenna selection in multiuser MIMO system is proposed which is based on block diagonalization as a precoding technique to cancel inter-user initerference. The proposed algorithm adopts the projection on the null of perpendicular effective channel as a performance metric. Simulation results show that our algorithm achieves very close to the optimum...
On behalf of the FGCT 2015 conference, the program committee has the pleasure to welcome the attendees to participate in the Fourth edition of the International Conference on the Future Generation Communication Technologies (FGCT 2015) which is dedicated to addressing the challenges in computing technologies for the new generation.
In traditional recommender systems, services/items are recommended to the user based on the initial ratings while the results comes from the predicted rating values are not considered which further refers to top N recommendations. In top N recommendation algorithms, recommendation process is further enhanced by predicting the missing ratings where the basic objective is to find the items that might...
The integration of WiFi and WiMAX will allow a seamless connection between users for both connections with larger capacity, higher speeds and mobility access. A special router is needed to allow the interconnection between two different protocol network known as WiFi/WiMAX router. In this paper, we investigate and simulated based on the scenario using OPNET modeler simulation tools and compared their...
A cooperative based Guided Local Search (GLS) framework has been proposed to deal with difficult combinatorial optimization problem in [1], [2]. This framework is called Population Based Guided Local Search (P-GLS). In P-GLS, we study how GLS performance can be further enhanced thorough designing a cooperative mechanism based on the search principle Proximate Optimality Principle (POP) [3]. The experimental...
This paper presents a novel approach to complex classification of heart abnormalities registered by electrocardiogram signals. It uses a combined approach of a Fast Fourier Technique for signal filtering and R-peaks detection and heart rate extraction, followed by signal modelling and classification by neural network based on recording of ECG. Obtained information is processed together for a complex...
In this paper we provide a review for the time domain analysis of the normalized timing error dynamics of a wireless receiver Early-Late tracking loop (A loop that controls the timing of a pseudo-noise code that is locally generated in the receiver). This review shows that the timing error dynamics modelling is cumbersome and can be simplified by linearizing the tracking loop. The linearization assumption...
The purpose of this paper is to explore the importance of Information Technology (IT) Governance models for public organizations and presenting an IT Governance model that can be adopted by both practitioners and researchers. A review of the literature in IT Governance has been initiated to shape the intended theoretical background of this study. The systematic literature review formalizes a richer...

Email is one of the most popular Internet ap- plications which enables individuals and organisations alike to communicate and work effectively. However, email has also been used by criminals as a means to commit cybercrimes such as phishing, spamming, cyberbullying and cyberstalking. Cyberstalking is a relatively new surfacing cybercrime, which recently has been recognised as a serious social and...
Advancements in hardware, software, and computing technologies make the design and application of series and diverse kinds of networks deployment in several environments possible. An instance of such networks greeted with the enormous interest in research and industries is the vehicular ad-hoc networks (VANETs). Currently, information dissemination in the practical communication networks is achieved...
Nature-inspired computing algorithms (NICs in short) inherit a certain length of history tracing back to Genetic Algorithm and Evolutionary Computing in the 50’s. Since February 2008 by the birth of Firefly Algorithm, NICs started to receive lots of attentions from researchers around the global. Variants and even new species of NIC algorithms boomed like sprouts after rain. While it may be disputable...
