| In this project, we design and implement a low-cost and flexible software defined radio based sensing and communication system for various unmanned aerial vehicles (UAVs). This design provides a practical solution for various UAV applications where adaptable and high performance communication is required. The regular communication system for most of the commercial UAVs performs in the unsilenced industrial, scientific, and medical radio (ISM) band, which is highly affected by high interference and lack of security. However, the proposed designed has a fairly wide frequency range and can provide the desired flexibilities in dynamic network condition through the usage of software defined radio communication. Several design parameters including level of autonomy, number of UAVs in the system, types of communications used, required frequency range and the security of the system are considered in the proposed design. The system consists of a radio base station Universal Software Radio Peripheral (USRP) N210, unmanned aerial vehicles, USRP B200, Arduino Uno and Raspberry Pi which will serve as the processing unit. One of the main reasons for this system is to successfully track wildlife creatures and collect meaningful data. The radio system will be built on the UAV and it will fly over the areas where the animal is expected to be and look for the radio-frequency identification signal. After the animal is found, the UAV will send the location and other sensor-collected data to the base station. The addition of an SDR system will allow us to autonomously change radio parameters using software on the UAV, track and collect data from different wildlife. |
