The NITOS Wireless Sensor Network Testbed for Experimenting with Long-Range Technologies.

In this work we demonstrate the NITOS Wireless Sensor Network testbed that allows remote and reproducible experimentation at city-scale, employing long-range wireless protocols. Specifically, we deploy 10 custom-made LoRa-enabled nodes in the city of Volos, Greece, coupled with an embedded device utilized as a means to provide remote access and configuration as well as for monitoring the experiments upon execution. Moreover, the testbed offers power consumption monitoring capabilities being able to capture the power draw of the entire sensor node, while also of individual modules such as the attached wireless interface, to characterize the energy-efficiency of new protocols.
