Within areas lacking appropriate or having no wire infrastructure at all, fixed WiMAX is recognized as a viable business solution for delivering broadband services to the end users. While in developing countries (like Bosnia and Herzegovina), such areas are widespread among suburban and rural topography, it is of great interest to provide preconditions for(More)
This paper presents the use of coupled BEM/FEM method by the numeric calculations of protection current/potential distribution when the cathodic protection system with galvanic anodes is applied. Cathodic protection (CP) system is very efficient system for protection of underground metal object from corrosion. The most important phase by installing the CP(More)
Each day the Internet connects more people, increasing the need for transmitting secure information. One way to protect the data sent over the web is to conceal the relevant information inside a typical image, hiding the data from intruders. This paper proposes a hybrid heuristic, combining a genetic algorithm and the path relinking metaheuristic to(More)
This paper proposes a cryptographic key establishment method based on set of images shared by sender and receiver. The method is simple, fast and secure. We call it CryptoStego. Possible key sizes are virtually limitless. Proposed method is implemented in C programming language. The implementation is compared with (A)RC4 stream cipher, by comparing CPU time(More)
This paper analyses a dependence of standard definition IPTV service continuity error on code violation block codes. A very reliable method of evaluating of several IPTV QoS parameters by observing the parameters of physical layer of DSL transceivers was introduced. Also, an ability to use the procedures, which have already implemented at common ATU-R and(More)
Wireless technologies, developed within ICT at the end of XX, beginning of XXI century, are followed by adequate analytical support, which also made their implementation faster. At the beginning, their similarity with WiMAX concept launched the implementation of WiMAX systems in the scope of closely related research achievements. Therefore, this paper in a(More)
Importance of digitalization of AV (audio/video) signals, produced in TV studios, has been recognized long time ago, and in many countries, TV studios abandoned old analog transmission, leaving place for digital signal transmission. In Bosnia and Herzegovina, TV studios are still producing and broadcasting analog PAL signal, but according to recommendation,(More)
Wireless data services, boosted by the massive use of popular Internet-based services such as email, WWW, etc., wireless wideband networks capable of supporting mobile multimedia services have attracted increasing intention in last few years. An important requirement has been postulated for these wideband services — they cannot be substantially more(More)
