Abstract
Low Power Wide-Area Networks (LPWANs) are gaining a lot of attention in use cases related to the Internet of Things . Most LPWAN communication technologies are asymmetric and have inherently better uplink communication, thus can implement ubiquitous monitoring and data collection efficiently. On the other hand, there is a growing demand for a sizable downlink channel. This work aims at providing a framework to study the feasibility of extensive downlink communication in LoRaWAN with moving End Devices (EDs). Starting from a real-world implementation of a Firmware Update Over the Air application, we experiment with two simple strategies to reduce packet loss when EDs move from within range gateway to another. Then, we extend the ns-3 LoRaWAN module to scale up the study by means of simulation. Such tests show that the chosen strategy and the deployment of the gateways have a strong impact on packet loss and on the time needed to complete the transmission of the data to the EDs. The code of the ns-3 module is available athttps://github.com/madsthom/lorawan.
