Abstract
This study aims at comparing the performances of two wireless sensor network (WSN) architectures which share the same end nodes, but differ from the gateway and the communication protocol, namely raw-LoRa and LoRaWAN (868 MHz). Both the architectures rely on open-source components for time-series storage and network management. Moreover, the key physical building blocks have been implemented through open-source compliant hardware elements. All these aspects have made it possible to achieve two flexible and low-cost platforms for environmental monitoring applications, among others. Data collected in the context of two European projects allow us to assess the reliability and the drawbacks of the two WSNs, when applied to an urban monitoring scenario
