After disasters occurrence, advanced technologies always play significant contributions to various disaster response tasks. For instance, utilization of Unmanned Aerial Vehicle (UAV) for aerial imagery data helps to get a real-time monitoring system of the stricken areas. Recently, UAV is becoming a ubiquitous system and valuable technology in many civil applications, motivating researchers to endeavor to develop UAVs systems. Moreover, Internet of Things (IoT) has been employed to several study cases of disaster response. Using IoT to communicate, manage and control multiple UAVs after disaster occurrence is a real practical approach. However, this kind of integration wasn’t clearly presented especially in the technical sides like communication and autonomous control. Consequently, this paper aims to reveal the scientific scenes of communications and controls between multiple UAVs and Ground Control Stations (GCSs). Due to an unexpected failure within a single UAV system, this study presents a multi-UAV system for scanning and tracking missions. Authors turned UAV to an IoT device by using embedded LTE dongle on the UAV control board. In the beginning of the paper, authors raised the issues of existing systems. Then, presented the design and process of the proposed system. Lastly, they demonstrated some results through experiments.
