Robust Data Transmission in 5G Networks Without Infrastructure Based on Blockchain Technology

Mobile ad hoc networks are faced with various security challenges emanating from malicious attacks. Their dynamic nature make nodes more vulnerable to attacks from either malicious nodes or intruders since there is no fixed infrastructure resulting in each node acting as router to transmit data. Currently, several solutions have been proposed and implemented in different ways aimed at eliminating or reducing these malicious attacks. This document proposes a model to increase the robustness of data transmission using blockchain technology. As blockchain technology forms the basis of our robust model, the simulation results obtained were analysed in terms of blockchain parameters. The achieved results show that the blockchain technology implemented in the MANET network ensures the elimination of malicious nodes in the network, based on changed or discarded data packets by individual nodes. In addition to these parameters, we analysed the proposed network in terms of the number of generated blocks and the rate of malicious nodes in the network, because these parameters have a great impact on the robustness of data communication.
