Study of Implementing Available Security Controls of Wireless Computer Networks

This article will present an analysis of security levels of wireless home networks based on IEEE 802.11 standard. The analysis of security implementation will be done on the basis of activated security checks available to end users in order to protect their own wireless system to the full. The analysis will encompass average users as regards to their knowledge of network communication systems and implemented security checks. The end result, i.e. a realistic picture of the way end users think about wireless computer network security, which in turn will have an impact on science and society in general, will enhance the awareness of possible ways wireless networks can be abused.

Guidelines for Developing e-Learning System for Visually Impaired

According to the last “People with Disabilities Report” (cro. Izvješće o osobama s invaliditetom) in Republic of Croatia lives 529 103 persons with disability which is more than 10 % of total population. There is 18 317 persons with impaired vision (blind and visually impaired). Compared to previous years this number has increased by 2044 people. According to estimates 10%, with a tendency to increase, of blind people is using the Internet. Estimates are based on documents and reports that are currently derived from the project “Communication Rod to Independence” (cro. Komunikacijskom štapom do neovisnosti). This paper will discuss described definitions and standards that will be im-plemented in learning management system (LMS) as a module for visually im-paired. LMS developed at the Faculty of Transport and Traffic Sciences has been in use since 2004. System is composed of five modules: Document Management System (DMS), The Authorization and Supervision System (cro. Sustav Autorizacije i Nadzora; SAN), students module e-Student, SMS module SMSCentar and mobile learning module FPZMobile.

Modelling of System for Transport and Traffic Information Management in Republic of Croatia

The traffic system is expected to provide faster, safer, more reliable, more comfortable and less expensive movement with enabling of maximal personal mobility. One of the necessary preconditions to realize these expectations is the real-time information of all those participating in the traffic processes with all the relevant data. Consequently, it is necessary to design and construct a traffic system that will, with the application of advanced information communication technologies (ICT), insure the backbone that will integrate the users’ services based on the principles of intelligent transport systems (ITS), in order to be able to provide the system users with reliable, precise and timely information necessary for a more efficient realization of the transport process.

With the application of modern ICT, the system for traffic information management collects, performs the adaptation process, fusion and processing (verification and addition of weights to each collected information) and carries out the distribution to all the interested users. Thus, new services may be offered that directly contribute to the improvement of traffic system quality by improving the change of space – time (s, t) coordinates (Figure 1) of the transported entity which is transported or transferred in adequate transport entity and moves with it along the transport network, with better efficiency of the consumed energy and less polluted environment.

Reminder Based on the User’s Location

The sense of technology and its future development has been primarily led by the idea of finding ways in which to make life for people easier. Simplicity, practicality and functionality represent characteristics of good products. Mobile information and communication technology determines the society and behaviours since it represents an element of individual quality and a way of communicating and doing business. The potential provided by hardware can be fully used only by adapting to the users’ requirements by improving the software side. Today’s development of the information and communication technology has to be created with the focus on the humans and with technology transparent for the user.
Regarding the mobile information and communication technology, the problem has traditionally been that the mobile applications focused too much on the technology, which means that applications had been developed for certain purposes or for special technologies. The new standpoint has been led by the idea that the application has to provide the users with what they want, anywhere they want it and in the best possible way. The user has to be able to employ the mobile device and software based on the installed applications in different environments and independent of the environment.
Developing an application that may make everyday life easier is a sufficient motive to turn an idea into reality. The topical feature of the application development technology for mobile devices called for an idea that would take into consideration the users’ requirements and satisfy them by providing a simple solution for their everyday life. This idea is a reminder based on the user’s location.

XaaS Services as Modern Infrastructure of e-Goverment in the Republic of Croatia

The emphasis of research on the analysis of features, and effects of new innovative services ICSP’s in Croatia, based on XaaS paradigm, the function of implementing the necessary e-communications infrastructure and services for good governance, development and competitiveness of the Republic of Croatia.

The Framework of e-Forensics in the Republic of Croatia

With the development of information communication systems and the services they provide, the complexity of the organization of information within information systems is growing. The complexity itself contributes to the increase in the number of electronic incidents and affects the high demands of forensic procedure implementation. It is estimated that in the near future the number of electronic incidents will outgrow the number of classical criminal incidents both financially and quantitatively. Due to the things mentioned above, early identification, discovering and taking legal proceedings against the perpetrator of an electronic incident are necessary. It is necessary to investigate all electronic incidents adequately and promptly and adapt the legal framework and laws related to e-Forensics. e-Forensics is a relatively new discipline within which there is a low level of standardization and consistency. With the purpose of increasing the quality of performing e-Forensics and presenting the evidence in a possible judicial proceeding one has to define the legal framework of e-Forensics. The analysis of current legal standards and methods used to perform e-Forensics is presented in the paper as well as the proposal of performing e-Forensics with defined procedures and methods.

Model of the new LMS generation with user-created content

The Learning Management System (LMS) of the Faculty of Transport and Traffic Sciences has been in operation since 2004 when it was developed for the studying purposes according to the German Fachhochschule study concept and according to the then specific characteristics of studying in the Republic of Croatia. The system consists of five own developed modules (DMS, SAN, e-Student, SMSCentar and FPZmobile) which in synergy form the Faculty LMS. The Document Management System (DMS) is a system of managing documents and processes used for authorized access of the Faculty staff members to the modules that control the work of computer laboratories, e-Learning system administration (publishing of teaching materials, control and assessment of seminar papers, etc.), as well as the module for managing documents and processes within the Faculty (orders for equipment, reports on malfunctions, updated on-line directory, etc.). The authorization and supervision system (SAN) is a set of technologies and applications that allow supervision of students’ work on computers in computer classrooms of the Faculty, and personalization of the working environment in the Windows operating system, regardless of the particular computer the student is using. The e-Student system allows students authorized access to the teaching materials, tasks, exercises and instructions. Apart from this the system provides support in applying and producing seminar papers and various forms of knowledge testing (e-Blic, e-Test, e-Kviz). The SMSCentar and SAN system with smsCRM application (Customer Relationship Management via SMS) open up the possibilities for a number of information services for students and Faculty staff members based on interactive communication by means of SMS messages. Some three years ago, the m-Learning module was added to the e-Learning system of the Faculty in the form of interactive application for real-time information of students via mobile terminal devices, called FPZmobile. The basic idea was to develop an application that will provide accurate and up-to-date information related to the Faculty and the students’ achievements (seminars, exercises, quizzes, etc.) during their studying, in a form suitable for browsing on the mobile terminal devices interface, such as mobile phones, PDA devices or Smartphones. The modularity of such a system allows fast implementation of the new services according to the ideas and suggestions expressed both by the teaching and the non-teaching staff, and the students.

Conceptual Model of Developing a New LMS System of the Faculty of Transport and Traffic Sciences

The e-Learning system of the Faculty of Transport and Traffic Sciences has been continuously developed since 2004 for the study requirements according to the German study concept of the Fachhochschule and according to the specific study characteristics in the Republic of Croatia, using a modular approach. Currently there are five modules functioning (DMS, SAN, e-Student, SMSCentar and FPZmobile) which together form the Learning Management System (LMS) of the Faculty of Transport and Traffic Sciences.
DMS (Document Management System) is a system for managing documents and processes which is used for authorized access by the Faculty staff members to modules: control of work of the computer laboratories (check of access to exercises, etc.), e-Learning system administration (publishing of teaching materials, control and grading of seminar papers, etc.) and the module for documents and processes management within the Faculty (orders for equipment, report on failures, updated on-line directory, etc.)
SAN (cro. Sustav autorizacije i nadzora, eng. The authorization and control system) is a set of applications which applies the advanced IT technologies to allow supervising the work of students on the computers at the computer laboratories of the Faculty of Transport and Traffic Sciences and personalization of the working environment in the Windows operation system, regardless of which computer is being used by the student.

Possible Collision Avoidance With Off-Line Route Selection

The paper describes the traffic flow problems in telecommunication networks based on the Internet protocol. The main aim of telecommunication network operator today is to offer an SLA (Service Level Agreement) contract to end users, with provided QoS for different classes of services. In order to achieve this, it is necessary to establish the routes between marginal network nodes meeting the network traffic requirements and optimizing the network performances free of simultaneous flows conflicts. In DiffServ/MPLS networks traffic flows traverse the network simultaneously and there may come to collision of concurrent flows. They are distributed among LSPs (Labeled Switching Paths) related to service classes. In LSP creation the IGP (Interior Gateway Protocol) uses simple on-line routing algorithms based on the shortest path methodology. In highly loaded networks this becomes an insufficient technique. In this suggested approach LSP need not necessarily be the shortest path solution. It can be pre-computed much earlier, possibly during the SLA negotiation process. In that sense an effective algorithm for collision control is developed. It may find a longer but lightly loaded path, taking care of the collision possibility. It could be a very good solution for collision avoidance and for better load-balancing purpose where links are running close to capacity. The algorithm can be significantly improved through heuristic approach. Heuristic options are compared in test-examples and their application for collision control is explained.

Application Development for Geo-Referenced Audio Video Recording of the Traffic System Using Mobile Phones

The paper analyzes the development feasibility and the possibilities of using the application for mobile terminal devices with the aim of generating geo-referenced audio-video recordings of the traffic network. The application has been developed at the Faculty of Transport and Traffic Sciences in Zagreb, in J2ME environment. The application is meant to create a geo-referenced audio-video recording of the traffic network, and can therefore be efficiently applied by all who are involved in activities regarding the general condition of roads, road signage, road environment, in short, by anyone who may benefit from the geo-referenced audio-video recording of the traffic network in order to operate more efficiently.
