The increasing processing power that personal computers have nowadays determined an accelerated evolution of the quality of video games regarding the graphic details, sound effects and simulation of physical phenomena. All these improvements aim to present a more realistic world in the game, such as Asseto Corsa, a racing car simulator that aims to provide a driving experience as close as possible...
Nowadays, the internet is playing a major role in everyday life, becoming the first choice for sharing information. In the last sixteen years the number of websites increased from three million to almost one billion. An important contribution to this number was brought by the content management systems which provided an easy approach for any user to create its own website without having advanced programming...
The networking industry faces nowadays with the emergence of a somewhat revolutionary paradigm that is intended to rethink network architectures, with the intention to mitigate the limitations that appeared in the traditional networks: Software Defined Networking (SDN). This paper illustrates differences between some SDN controllers, which represent the “brains” of the network. POX, Ryu, ONOS and...
Our keystroke-based user identification system represents a minimal implementation of a software system that can be used for continuous authentication of users, based on their keystroke dynamics. This paper brings into evidence the role of an alerting subsystem as a part of the software system mentioned above. Also, the paper presents a basic implementation of such a subsystem, based on the existing...
In this paper we propose several solutions to combine the use of two algorithms for patterns recognition and user validation, both intended to be used in the same time to improve the overall performance of the validation process in a continuous authentication system based on keystroke dynamics. The first one is based on a Multi Layer Perceptron (MLP) Neural Network and the second one relies on a trust...
In this paper we introduce a continuous authentication system based on keystroke dynamics (BIOMETRIC). We also propose two algorithms for extracting patterns and validating the user, both intended to be used in the same time to improve the overall performance of the validation process. The first one is based on a Multi Layer Perceptron (MLP) Neural Network and the second one relies on a trust algorithm...
The effects of the coexistence of different wireless access technologies in the same area are not very easy to be evaluated and analysed. If these different networks interact with each other and form a heterogeneous wireless network, the analysis becomes even more difficult. Different approaches are possible: to build a pilot heterogeneous network (but, if new technologies or, at least, existing technologies...
The paper describes a video streaming application build to evaluate session continuity over wireless hybrid access networks in vertical handover (VHO) conditions. The results showed us which components have to be improved. Further developments will address these improvements.
In this paper we describe a media streaming application build to test a system which implements the IEEE 802.21 Media Independent Handover (MIH) standard, for interoperability between wireless hybrid access networks. We evaluated the real-time performance of our vertical handover prototype system by means of the audio streaming continuity assessment. The current results proved only moderately performances,...
Multiuser detection technique implies joint demodulation of overlapping data streams of data sent by different users, improving their individual performances based on the knowledge of some key parameters of all users. Each user is identified by its own signature code, which should be, in the ideal case, orthogonal on all the others. Several multiuser detectors have been developed for synchronous CDMA...
During the last years, software applications performing scenarios related to vertical handovers were revealed. However, the great majority of these demonstrators were designed and optimized for multimode notebooks, having a fair amount of processing power. This article aims to describe on how to implement and optimize the main components of the IEEE 802.21 standard on a device like a smartphone powered...
In this paper we describe a context-aware reconfigurable system, which implements the IEEE 802.21 Media Independent Handover (MIH) standard for interoperability between wireless hybrid access networks. The proposed approach uses vertical handover prediction algorithms to improve the resource management decisions, through access to our Web Service implementation of the Media Independent Information...
When developing a network management system, the developer is faced with many choices concerning how to interact with the network resources and how to embed into the schema of manager agent architectures. In this paper we propose NMX (Network Management Extensions), a software framework implementation based on Java JMX (Java Management Extensions) technology and SNMP (Simple Network Management Protocol)...
This paper describes a solution for implementing the Media Independent Information Service, later referred to as MIIS, described in IEEE 802.21 standard. First we present the previous work towards defining a complete system capable of realizing a vertical handover according to the standard. Next we detail the MIIS general architecture, the information gathering procedures and considerations about...
In this paper we describe the design and implementation details of a mobile application supporting news access and virtual community interactive services, based on open technologies such as Java programming language, Java Mobile Edition (Java ME) libraries, MySQL database and an open Web server. The goal was to create an easy to use, mobile, interactive, flexible and extensible client-server solution,...
This paper provides a view on the developing process of the Media Independent Information Service, later referred as MIIS, described in the IEEE 802.21 standard, which has the main functionality of providing the mobile terminal information about all access points in his coverage area. Our approach is towards the management of the entire mechanism of delivering data to the device, that is realized...
