“…Visually, both recordings offered no observable difference and similar results were observed for other speeds. On contrary to the findings in[38] who reported a significant influence on PRR even at speed 8kmph, the experiment results show no observable influence on PRR nor spectrogram records even at high speed of 80kmph.…”

“…Apart from a static deployment of sensors, in some cases, sensor networks might employ mobile sensor nodes too. The impact of nodes mobility on the performance of LoRaWAN has also been studied by Patel and Won [9], and two key findings have been reported: (i) LoRaWAN is susceptible to mobility; and (ii) the effect of mobility worsens the performance for end-nodes in case of bad reception conditions (indoor systems or far from gateway).…”

The response conducted by emergency units after natural disasters, such as earthquakes, has to be coordinated, fast, and efficient in order to rescue and care for the victims, keeping all the population-and the units themselves-safe amidst the usual chaos. Outages in wireless networks, as well as fiber-or copper-based landline and Internet connections, are to be expected in these situations, so alternative communication solutions must be considered. To contribute in this duty, we propose a communication system that uses the LoRaWAN architecture to allow citizens to report their status to emergency units and public authorities with simple messages and interaction mechanisms. The purpose of this system is to keep people and first responders connected, and thus improve the capability to coordinate the evacuation activities. To analyze the system performance and capabilities, we model a district of Coquimbo, a harbor town in Chile that houses approximately 28,000 people in 7500 homes, and simulate it with a baseline configuration. We explore several settings for the system in order to determine its characteristics and limitations, to better understand its scalability and portability to other environments, and to outline the remaining challenges to make the system attain specific performance guarantees.

Thus, the impact of mobility on the performance of LoRaWAN has been studied in [ 30 ]. Two key findings regarding the impact of mobility on LoRaWAN have been reported: (i) LoRaWAN is susceptible to mobility; and (ii) the effect of mobility worsens the performance for end nodes in case of bad reception conditions (indoor environments or far from gateway).…”

LoRaWAN is one of the low power wide area network (LPWAN) technologies that have received significant attention by the research community in the recent years. It offers low-power, low-data rate communication over a wide range of covered area. In the past years, the number of publications regarding LoRa and LoRaWAN has grown tremendously. This paper provides an overview of research work that has been published from 2015 to September 2018 and that is accessible via Google Scholar and IEEE Explore databases. First, a detailed description of the technology is given, including existing security and reliability mechanisms. This literature overview is structured by categorizing papers according to the following topics: (i) physical layer aspects; (ii) network layer aspects; (iii) possible improvements; and (iv) extensions to the standard. Finally, a strengths, weaknesses, opportunities and threats (SWOT) analysis is presented along with the challenges that LoRa and LoRaWAN still face.
