Abstract

The constant need to monitor devices has increased in recent years to the point that devices are not only tracked outside, via GPS or similar systems, but inside too, using Internal Positioning Systems. These systems are usually using Wi-Fi signal and other sensor information to determine de the smart device location. This article presents the implementation of a simple position monitor for smart devices inside buildings using Raspberry Pi as the smart device and the Wi-Fi signal strength for distance indication. Wi-Fi AP location is considered fixed for this implementation.
