Recently, localization in Global Positioning System (GPS) denied environments has witnessed an increase in interest, due to the potential wide range of using in different applications, such as Internet of Things (IoT) providing a solution for the absence of GPS signals inside buildings and tunnels. Different techniques have been used for performing this type of localization, such as sensors and wireless technologies. In this paper, localization and object tracking system is proposed based on WiFi transmission technique. It is done by deploying a WiFi access point with an Unmanned Aerial Vehicle to fly autonomously in such places to read the data of the tracked objects. This is to measure the received signal strength and distance between the WiFi access point and the object to allocate and track it efficiently. The test results show that the proposed system is working in an efficient way with low cost.
