The use of aerial vehicles in applications such as disaster management has a significant impact on society. One of the challenges in developing technologies that utilize these vehicles is the ability to carry out tasks or missions as a group of nodes, thereby efficiently reaching points of interest or transmitting valuable data. This study proposes an evaluation of the performance of a multi-UAV (Unmanned Aerial Vehicle) network using different channel models on a critical scenario of point of failure between two nodes. In this potential application scenario defined, a transmitter and receiver exchange User Datagram Protocol (UDP) packets through a relay node. Metrics such as Bit Error Rate (BER), Packet Delivery Ratio (PDR), and Energy Consumption were used to quantify the system's performance with various modulations and traffic loads. The difference in impact between channels became noticeable at medium to high traffic levels, where, for instance, using BPSK modulation resulted in an energy savings of up to 10% compared to 64QAM, while maintaining a PDR above 90%. This trade-off between energy efficiency and communication quality was crucial in selecting the channel that best meets the application requirements.

摘要

The use of aerial vehicles in applications such as disaster management has a significant impact on society. One of the challenges in developing technologies that utilize these vehicles is the ability to carry out tasks or missions as a group of nodes, thereby efficiently reaching points of interest or transmitting valuable data. This study proposes an evaluation of the performance of a multi-UAV (Unmanned Aerial Vehicle) network using different channel models on a critical scenario of point of failure between two nodes. In this potential application scenario defined, a transmitter and receiver exchange User Datagram Protocol (UDP) packets through a relay node. Metrics such as Bit Error Rate (BER), Packet Delivery Ratio (PDR), and Energy Consumption were used to quantify the system's performance with various modulations and traffic loads. The difference in impact between channels became noticeable at medium to high traffic levels, where, for instance, using BPSK modulation resulted in an energy savings of up to 10% compared to 64QAM, while maintaining a PDR above 90%. This trade-off between energy efficiency and communication quality was crucial in selecting the channel that best meets the application requirements.
