GNSS IoT Positioning From Conventional Sensors to a Cloud-Based Solution

摘要

The advent of the Internet of Things (IoT) has considerably increased the number of services and applications that require positioning information. In this sense, IoT positioning sensors usually obtain and deliver their position to a central node where it is further managed and analyzed by a user or scheduler. Nonetheless, the stringent requirements of low-cost IoT sensors in terms of low power consumption to achieve larger battery lifetime are pushing current technologies to their limits. In this context, we propose a cloud-based Global Navigation Satellite System (GNSS) solution to deal with the typical constraints faced by IoT sensors by migrating the signal processing tasks from the sensor to cloud servers. Theoretical and experimental results demonstrate the feasibility of a cloud-based GNSS approach in energy efficiency, performance, and economic terms.
