Abstract

Low Power Wide-Area Networks (LPWANs) are gaining a
lot of attention in use cases related to the Internet of Things. Most LP-
WAN communication technologies are asymmetric and have inherently
better uplink communication, thus can implement ubiquitous monitor-
ing and data collection eciently. 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 at https://github.com/madsthom/lorawan.
