On December 1, we organized a scientific seminar on “Robust Data Transmission in 5G Networks without Infrastructure“. The scientific seminar was led by Maroš Baumgartner, a lecturer at Slovak University of Technology in Bratislava. The scientific seminar was organized in the framework of the FrontSeat project as part of the seminar series on “Research Seminar on Smart Cybernetics”.


The resilience of mobile networks is one of the biggest challenges for data transmission in networks without infrastructure. Communication under current routing protocols is through a communication path that, although the shortest, may not perform satisfactorily in terms of resilience. Routing and communication within such a path may occur using malicious or inappropriate nodes in the communication process due to maliciousness or poor technical state. In this paper, an algorithm for resilient routing in mobile multi-hop networks has been proposed. The algorithm based on decentralized blockchain technology and artificial intelligence has been implemented in the reactive and proactive routing protocols. The objective of this algorithm was to select the most appropriate communication path from source to destination node in terms of resilience. The selection of such a communication path consisted of selecting the most suitable node in terms of resilience, where the selection of such nodes was provided through a network and technical parameters. The key metrics of quality of service, throughput, total delay, number of signaling and data packets delivered, and the ratio between them were used to evaluate the proposed resilient routing algorithm. From the results obtained, it could be concluded that the modified resilient routing protocols achieved improvement in all the analyzed parameters compared to the original reactive and proactive protocols. The improvement in these parameters led to an increase in the resilience of the routing process based on the actual data obtained from each node in the network and previous communications.
