A Comparison of Signal Strength Localization Methods with Sigfox

2018 15th Workshop on Positioning, Navigation and Communications (WPNC), 2018
Location-based services play an important role in Internet of Things (IoT) applications. However, a trade-off has to be made between the location estimation error and the battery lifetime of an IoT device. As IoT devices communicate over Low Power Wide Area Networks (LPWAN), signal strength localization methods can use the existing communication link ...
