It is a well-known fact that nowadays access to sensitive information is being performed through the use of a three-tier-architecture. Web applications have become a handy interface between users and data. As database-driven web applications are being used more and more every day, web applications are being seen as a good target for attackers with the aim of accessing sensitive data. If an organization...
Video streaming through Internet faces different challenges caused by network performance and heterogeneity nature of internet. The larger the distance between end-user and streaming server the stream passes through different networks and causes delays which affect the user quality of experience (QoE). An optimal approach to minimize delays and offer high video quality is Cache implementation. Operators...
Air quality degradation is the result of combining different substances which consist of solid particles in the air. Such particles can be: ozone, car emissions, different chemicals from factories, etc. Some of these substances are hazardous for human health. The lack of periodic measurements in different location makes it impossible to plan and act, in order to reduce the air quality high coefficients...
In this paper we will develop a system that could be used at science fairs to teach children regarding robotics. The system which we developed is named “dancing with the robots”. This system explains the basic parts of robot (sensing and acting) through a dancing activity. The system incorporates a Microsoft Kinect sensor, used to detect the dancing movements of a child and control a Lego EV3 robot...
Cyber attacks are becoming more and more sophisticated, obtaining access to sensitive data. These attacks are causing major damages to various organizations, such as financial losses, service disruption etc. In this paper, we will use Penetration testing technique in order to test network security. This technique uses the same tools and methods as malicious attackers use, in order to take control...
Technology is becoming more natural and intuitive. People already use gestures and speech to interact with their PCs and other devices. In this paper, we have developed an application interface to recognize human body gestures and reflect these gestures through Kinect sensor to Lego robot. The main contribution of this paper is implementation process of the system and development of application interface...
Quality of Service (QoS) refers to the possibility of networks to offer different services. Because nowadays we have an evolution of wireless customer's requests, it is needed to pay attention to QoS in WLAN (Wireless Local Area Network) standards. Thus, in this paper, we have analyzed the QoS of WLAN standards 802.11g and 802.11n, since they are most commonly standards used today. In order to evaluate...
This paper is focused on the Quality of Service (QoS) for the newest standards of WLAN (Wireless Local Area Network); 802.11g and 802.11n. QoS refers to the possibility of networks to offer different services. The QoS is needed in WLANs, because there is an evolution of the customer's needs for different applications. Oldest WLAN standards were used only for transmission of low bandwidth traffic....
IPTV (Internet Protocol Television) is one of the broadband services all operators tend to offer to the customers. Telecom of Kosova (TK), has implemented IPTV platform. This IPTV platform is integrated in NGN (Next Generation Network). In access network, TK has implemented copper cable and ADSL (Asymmetric Digital Subscriber Line) technology, whereas in core network has implemented optical network...
Telecom of Kosovo (TK) is an incumbent fix telecommunications service provider. In its efforts to keep the leading position in Kosovo's competitive telecommunication market, TK has implemented IPTV platform. The trend toward increasing the number of customers and their requirements for IPTV services, very soon will overcome Gbps capacities in core network. While we have a competition for bandwidth,...
As the demand for IPTV services increases, one of the main challenges for offering these services is fair bandwidth allocation among users requesting different IPTV video services. Most existing approaches treat all video streams equally, without taking into consideration that some video channels require higher bit rates than the others to reach the same quality. In this paper we present several algorithms...
It is well known that dipole antennas are suitable for applications in wireless technology, because they are simple to design and have excellent radiation properties. The analysis of series-fed printed strip dipole antennas gets complicated by the presence of dielectric inhomogeneity. In addition, the strip dipoles are closely spaced and connected through transmission lines that are integral part...
