| Abstract |
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. |
