Optimal Communication Handover of SAR Drone Based on Digital Twin Strategy

With various potential UAV applications, the deployment of drones in groups will increase, some of which will be ad hoc. The drone group's communications network is known as the Flying Ad-hoc Network (FANET). A reliable FANET is essential to ensuring the success of any particular operation, for example, during a disaster where the existing infrastructure is not available. FANET was formed to enable communication for rescuers (human and machine, including Search and Rescue UAVs), as well as victims, in calling for help. In order to collect data more efficiently, UAVs connected to the IoT (Internet of Things) are needed, where data is automatically collected from various sensors and directly sent through the cloud or data storage systems. However, FANET has major challenges in dynamic topology caused by the high mobility of UAVs, so this dynamic results in frequent communication handovers. To overcome this challenge, it is necessary to integrate the UAV swarm network in real time with the help of digital twin technology to find out the improved handover strategy in order to improve service quality.
