Energy-Efficient Indoor Localization WiFi-Fingerprint System: An Experimental Study

In order to apply indoor localization systems in real environments it is necessary to provide an accurate location without implying a high impact on the user’s normal behaviour. To achieve this goal, in this paper, a combination of battery saving techniques with a system based on WiFi fingerprinting...

To achieve this goal, in this paper, a combination of battery saving techniques with a system based on WiFi fingerprinting is proposed.

There are not many studies analyzing energy consumption of existing localization systems, even though it is an important factor in real applications. In this paper, both energy consumption and accuracy are analyzed, having an energy consumption of only 0.8 Wh (having a 3.7 V battery) during a 24-hour cycle and an average localization error of 4.51 meters.
