It is well understood, that cooperation among all entity participants crossing different sectors and borders should be facilitated. The cel-lular network communications, the radio frequency identification techniques and the high-level communication protocols are in fact all modern technologies complementary to each other. The article considers and makes comparison between traditional ways for GPS tracking and modern LoRa WAN devices, utilized in coastal waters. The utilization of such de-vices onboard of small leisure crafts or fishing vessels could be vital to support the operation of vessel traffic services. Cellular trackers have also the advantage to send distress alerts. Measurements of signal strength and quality have been presented to decide whether to utilize cellular network signal for emergency alerting and position reporting. So far, on the Bulgarian coast, the IoT gateway infrastructure might be insufficient but the growth rate is sufficiently high. The potential solution, presented in this article, could serve to improve the operational efficiency of marine traffic control.</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><section><style face="normal" font="default" size="100%">341</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Volodymyr Petrivskyi</style></author><author><style face="normal" font="default" size="100%">Georgi Dimitrov</style></author><author><style face="normal" font="default" size="100%">Viktor Shevchenko</style></author><author><style face="normal" font="default" size="100%">Oleksiy Bychkov</style></author><author><style face="normal" font="default" size="100%">Magdalena Garvanova</style></author><author><style face="normal" font="default" size="100%">Galina Panayotova</style></author><author><style face="normal" font="default" size="100%">Pavel Petrov</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Information Technology for Big Data Sensor Networks Stability Estimation</style></title><secondary-title><style face="normal" font="default" size="100%">Information &amp; Security: An International Journal</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">big data</style></keyword><keyword><style  face="normal" font="default" size="100%">coverage radius</style></keyword><keyword><style  face="normal" font="default" size="100%">data loss</style></keyword><keyword><style  face="normal" font="default" size="100%">sensor network</style></keyword><keyword><style  face="normal" font="default" size="100%">sensor network stability</style></keyword><keyword><style  face="normal" font="default" size="100%">sensors</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2020</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">47</style></volume><pages><style face="normal" font="default" size="100%">141-154</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Sensors and sensor networks are widely used in various industries and human activities and main components of the Internet of Things and Industrial Internet of Things concepts. Nowadays, huge amounts of data, called Big Data, can be transported and collected using sensor networks. This article presents approaches for providing sensor networks’ stability estimation for transporting Big Data and collecting respective use cases. The proposed estimation method allows to detect sensor network’s components that decrease data transport system stability. Consequently, additional connections or sensors can be added to increase stability. In the case of data collection, the solution consists of finding the most vulnerable sensor and an optimal position for the additional sensor with given intersection levels with other sensors. Simulation results confirm the feasibility and effectiveness of the proposed approaches.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><section><style face="normal" font="default" size="100%">141</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Volodymyr Shevchenko</style></author><author><style face="normal" font="default" size="100%">Georgi Dimitrov</style></author><author><style face="normal" font="default" size="100%">Denys Berestov</style></author><author><style face="normal" font="default" size="100%">Pepa Petrova</style></author><author><style face="normal" font="default" size="100%">Igor Sinitcyn</style></author><author><style face="normal" font="default" size="100%">Eugenia Kovatcheva</style></author><author><style face="normal" font="default" size="100%">Ivan Garvanov</style></author><author><style face="normal" font="default" size="100%">Iva Kostadinova</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">One-way Function Based on Modified Cellular Automata in the Diffie-Hellman Algorithm for Big Data Exchange Tasks through Open Space</style></title><secondary-title><style face="normal" font="default" size="100%">Information &amp; Security: An International Journal</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">cellular automata</style></keyword><keyword><style  face="normal" font="default" size="100%">Diffie-Hellman algorithm</style></keyword><keyword><style  face="normal" font="default" size="100%">one-way function</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2020</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2020</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">47</style></volume><pages><style face="normal" font="default" size="100%">233-246</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">The article deals with ways to quickly change passwords in information ex-change through open space. It suggests an improvement of the Diffie-Hellman algorithm by creating a one-way function on the basis of cellular automata with an extended set of rules. The authors have expanded the rules of the game of life towards definition of the rules of birth rate and life extension, control of the radius of intra-population interaction, rules of death from the age of cells, multi-component (multi-population) system of cells. The created algorithm on the basis of a cellular automaton is used to create keys for safe information transfer. Depending on the needs of encryption, the algorithm can be enhanced by using variable parameters of the cell field and cell behaviour, which will allow to regulate the speed and reliability of encryption. The implementation is in Python and MatLab, which allows to compare results and change the modelling environment when changing the features of the task.</style></abstract><issue><style face="normal"
