Abstract Telecommunication networks produce large amounts of alarm information daily. This data contains potentially valuable knowledge about the network. We present a methodology for the analysis of large telecommunication networks ...

Georgia Low income countries Europe World Fixed line telephony Main telephone lines (k), 2000 860 Main telephone lines per 100 inhabi-The market of communication se...

Telecommunications are strategic assets for the design and operation of train control systems based on automatic train protection to prevent errors due to the human factor. The ERTMS/ETCS train control system developed in Europe is considered a world-wide de facto standard. It utilizes a dedicated telecommunication network based on the GSM-R system. This approach is not economically sustainable...

Telecommunication systems are becoming increasingly complex. This is due to the size and heterogeneity of such systems, as well as to the complex interaction among network elements. In telecommunication system, wireless networks have witnessed tremendous development. Presently, the field of wireless sensor networks (WSNs) is an important and challenging research area. Advancements in sensor net...

In the past, telecommunication technologies did not present any particular problem for persons with visual disabilities. The telephones themselves were auditory in nature and could be operated by touch. As telecommunication begins to incorporate video and as telecommunication devices become more complex (including the incorporation of visual displays), new barriers are appearing. Fortunately, a...

We present algorithms for the drawing of survivable telecommunication networks. The visualization of telecommunication networks is a very important problem. For some specific rings in a network, we may have a high traffic. The network designers may decide to add more equipment to the nodes (sites) of these rings in order to increase the performance of the network. Therefore, one of the most imp...

Since the birth of ARPANET and the first commercial applications of computer networks, through explosion of popularity of the Internet and wireless communications, we have witnessed increasing dependence of our civilization on information services of telecommunication networks. Their efficiency and reliability have become critically important for the well-being and prosperity of societies as we...

Networks reliability analysis consists of determining the probability of correct operations of a system. Generally, the network is modeled as a connected graph and formally approached as a stochastic coherent binary system (SCBS). It represents the functioning of a system such as telecommunication and transportation networks, or simply hardware/software devices. Real networks model could be ver...
