In this paper a method for calculation of prediction propagation losses in suburban environment at 300 MHz frequency band is proposed. It is dedicated for short range (up to 1 km) communication link and takes into account location of the buildings. To estimate attenuation, proposed…

Information and communication technologies play a key role in ensuring business continuity. In most cases, companies did not envisage a scenario requiring employees to stay home and work remotely. In this situation, employees were unprepared and poorly equipped not only in terms of hardware and…

Software Defined Networking (SDN) means designing network solutions so that they can be controlled and managed dynamically and automatically using appropriate software. SDN architecture solves one of the most serious problems of today's computer networks, which are not very susceptible to changes and reconfiguration so…

The rapid increase of vehicle traffic volume in modern societies raises the need to develop innovative solutions to reduce traffic congestion and enhance traffic management efficiency. The intelligent transportation system (ITS) is an advanced technology that enables improved traffic management. However, ITS suffers from routing…

The use of a spatial selection of radio links in 5G networks is conditioned by the assessment of a power angular spectrum (PAS) of received signals. In this paper, we present a simulation procedure that allows the determination of the PAS for various environmental conditions…

In this paper, a performance of the Network Coding technique that has been adapted to 6LoWPAN-based networks is discussed. The proposed solution named NC6LoWPAN, initially tested in a real wireless sensor network, is then investigated by simulations in terms of packet buffering time and traffic…

This paper presents a study to build a prototype of an unmanned weather station operating as a LoRaWAN end device, equipped with a sensor with an autonomous power system using a battery charged by a solar cell and software created using the Arduino IDE. The…

The article presents the Rich Vehicle Routing Problem (VRP) that reflects a real problem for one of the food retailers network in Poland. To solve this problem a very fast algorithm was proposed basing on the savings heuristic and graph approach. The proposed algorithm was…

Technologies are constantly developing, and the area of ​​transport has no exception. Modern technologies significantly influence decision-making and management processes also in the field of transport. It can be assumed that the aim of deploying modern technologies in the field of transport is mainly to…

The article presents the chances and threats inherent in the use of the Internet of Things (IoT) as a modern technology in cyberspace, which is understood as a dynamically changing combat environment. The authors attempt to find answers to the following question: What is the…
