Spectrally Efficient MIMO-OFDM for THz Communication in FANETs

The primary properties of flying-ad-hoc-networks (FANETs), which are autonomous wireless networks, include high mobility, scalability for various applications, situations, and robustness to handle potential communication failures. They still face a number of limitations, including the restricted flying time of Unmanned aerial vehicles (UAVs) and lower throughput. Because the location of the UAV may be changed in FANET, it is possible to adjust the distance between two nodes and subsequently optimise the capacity of the related connection to increase network throughput. In this study, a simulation model for UAV ad-hoc network is built. Various antenna configurations are examined also. When we utilise up to a certain number of UAVs, the reduced latency makes single input single output (SISO) systems, capable of handling greater data rates. MIMO is shown to boost performance when the number of UAVs in the network surpasses a particular threshold, though. As the system's antenna count increases, its performance improves. The use of MIMO OFDM for terahertz communication in FANET is highlighted. The proposed architecture is built on the Marcov Chain paradigm. We arrive at the formulae for throughput, BER, path loss, and outage probability. When MIMO antennas are configured, the system's overall performance improves as its BER drops and its throughput rises.
