Nowadays, using Unmanned Aerial Vehicles (UAV) is applied to many applications such as rescue, streaming, monitoring. The UAVs’ ability can provide flexibility and efficiency in the monitoring operation. However, this poses different challenges, including topology management, resource allocation, and energy consumption for both UAVs and sensor nodes. To address these challenges, this paper discusses applying the approach of Software Defined Networking (SDN) to Unmanned Aerial System for monitoring sensor data, which provide abilities to manage UAV and sensor networks through a centralized SDN controller. The paper presents an architecture framework of SD-UAV and sensor networking. The comparison is performed between the networks with and without using the SDN approach. The results show the efficiency of using SDN to increases the bandwidth and decrease packet loss.
