LoRaWAN has become the most widely used low-power wide-area network technology
toimplement monitoring solutions based on the Internet of remote things (IoRT)
paradigm. Typically,these solutions interconnect remote sensing areas and data
processing infrastructure located in urbancenters. The operation expenses of
these solutions depend mainly on the traffic sent through thenetwork backhaul,
i.e., the link that connects the remote sensing area and the urban area where
thedata are usually processed and stored. This service is provided by
telecommunication companies andrepresents the main operation cost of IoRT
solutions. These expenses usually limit the affordability ofIoRT-based systems
in developing countries, and also in scenarios where the operational cost is
anissue to address. This paper presents an extension to the LoRaWAN protocol,
named Node-Aware-LoRaWAN (NA-LoRaWAN), that reduces the traffic in the
backhaul, thus decreasing the operationalexpenses of IoRT-based systems. In
order to evaluate the performance of NA-LoRaWAN, it wascompared to a regular
LoRaWAN implementation. Depending on the network scenario, the
proposedextension reduced the traffic through the backhaul in the range of
12-34%. This extension opensseveral opportunities to use IoRT solutions in
application domains with a low operational budget,e.g., precision agriculture,
environmental monitoring and natural hazards' early detection.
