Performance Evaluation of Routing Protocols iFORP-3DD for DANET Considering Drone Movement Speed

Unmanned aerial vehicles (UAVs), such as drones, are beginning to be utilized for various purposes. Currently, most communication between drones and their control terminals is one-to-one direct communication, with the range for transmitting data, such as video, limited to the direct reach of radio waves. As a solution to this problem, DANET, a drone-composed ad-hoc network, is gaining attention. However, existing protocols are insufficient for achieving adequate performance in DANETs. To configure a reliable DANET, we have proposed iFORP-3DD, an enhanced version of the iFORP routing protocol that incorporates cooperative control functionalities for managing the movement of relay terminals based on their location information and evaluated its communication performance. In this paper, we propose a route selection method using a cooperative operation approach that determines the duration of cooperative operation and movement speed according to the number of neighboring terminals in order to reduce the load on relay terminals and describe the evaluation results of the proposed method through simulation.
