Performance evaluation of LoraWan physical layer integration on IoT devices

Abstract

Due to the constant motion of wireless devices in the Internet of Things $(\mathrm {I}\mathrm {o}\mathrm {T})$, current wireless networks cannot provide connectivity in each case using altering topolgoies, in comparison with ad hoc networks. LoraWan, as a Long Range Wide Area Network recommended by the LoRa Alliance, is an upcoming candidate for low power and long distance communication $\mathrm {I}\mathrm {o}\mathrm {T}$ environments and applications to different concepts such as tracking, healthcare agriculture. This $\mathrm {I}\mathrm {o}\mathrm {T}$ concept is gaining a rapid growth on the $\mathrm {I}\mathrm {o}\mathrm {T}$ market and is simultaneously improving our living environment. In this paper, we first briefly introduce LoRa as an efficient solution of physical layer integration on the $\mathrm {I}\mathrm {o}\mathrm {T}$ devices. We then conduct a performance evaluation taking into consideration values such as bit error rate, time on air transmission based on Signal to Noise Ratio (SNR) and Spreading Factors modifications for different bandwidth values.
