Wireless positioning in IoT: A look at current and future trends
In this 2018 paper published in Sensors, e Silva et al. "highlight the importance of positioning features for [internet of things] applications and [provide] means of comparing and evaluating different connectivity protocols in terms of their positioning capabilities." Noting a lack of research on the topic of IoT connectivity solutions and how they are localized and tracked, the researchers present what related work there is on the topic, discuss positioning domains and systems, compare IoT technologies and enablers., and provide several case studies. They conclude "that power-domain positioning currently offers the best trade-off between implementation cost and positioning accuracy for low-power systems."
