![]() The working mechanism is as follows: one of the UAVs detect a human presence in a predetermined area with the thermal camera and then directs the UAVs to the location to enhance the weak signal and protect the transmitted data. This paper contributes to investigating the possibility of using a wireless repeater placed on a UAV as a mobile booster for weak wireless signals in isolated or rural areas in emergency situations and that the transmitted information is protected from external interference and manipulation. In such previous scenarios, boosting wireless signals in remote or isolated areas would need a mobile signal booster placed on UAVs, and, at the same time, the data would be secured by a secure decentralized database. On this basis, UAVs have been used in many military and commercial systems as emergency transport and air support during natural disasters and epidemics. Recently, the unmanned aerial vehicles (UAV) under the umbrella of the Internet of Things (IoT) in smart cities and emerging communities have become the focus of the academic and industrial science community. 11 Department of Electrical and Computer Engineering, Lebanese American University, Byblos 4307, Lebanon.10 Artificial Intelligence Research Center (AIRC), Ajman University, Ajman 346, United Arab Emirates.9 Faculty of Computer Science &Engineering, Galala University, Suze 435611, Egypt.8 Department of Mathematics, Faculty of Science, Zagazig University, Zagazig 44519, Egypt.7 Department of Information Technology, College of Computer and Information Sciences, Princess Nourah Bint Abdulrahman University, P.O.6 College of Computer and Information Science, Southwest University, Chongqing 400715, China. ![]() ![]() 5 Department of Computer Science and Technology, Zhejiang University, Hangzhou 310000, China.4 Optical Communications Laboratory, Ocean College, Zhejiang University, Zheda Road 1, Zhoushan 316021, China.3 College of Physics and Electronic Information Engineering, Zhejiang Normal University, Jinhua 321004, China.2 College of Software Engineering, Northeastern University, Shenyang 110169, China.1 Department of Management Science and Engineering, Dalian University of Technology, Dalian 116024, China. ![]()
