Unmanned Aerial Vehicle Swarm Uses Wi-Fi to Search for Stranded People in Remote Areas Embedded devices as active scanners in search for Wi-Fi-enabled mobile phones

Ever since new System on Chips got more powerful and integrated into small scale printed circuit boards, with the development of new generation processors, a whole new generation of devices started to appear in everyday life. Two of the most intriguing one are smartphones and air drones or UAVs (Unmanned Aerial Vehicles). This paper suggests that combination of both can significantly add to cost effective Search and Rescue (SAR) operations in remote areas with no terrestrial infrastructure available and only GPS as guidance.

I. Introduction

Perhaps one of the most plastic examples of continuous progress of embedded circuitry and engineering are modern multi-function enabled mobile phones, also commonly known as smartphones - a title they deserve for many reasons. Not only they are good examples of technology progressing at fantastic rate, they are also examples of technology that managed to reach almost 50 [%] of the world population in 2021 [1] and almost every person [2] in technically developed world. Aside the design and practical functionalities, those devices nowadays (e.g. iPhone6, as proposed by [8]) have the computing power that is 120 million times the one of the Apollo 11 Guidance computer that was built by Massachusetts Institute of Technology (MIT) and sent on a moon mission in space in 1969. [3] That computer had cycle of 43 [kHz] and 64 [kB] of memory with over 30 [kg] in mass.
