Abstract
In this paper we present results of the simulation analysis of the impact of transmission parameters and distance between LoRa node and gateway on communication performance (packet loss rate and energy consumed by nodes). FLoRa simulation framework based on Omnet++ was used to vary spreading factor, bandwidth, coding rate and transmission power. For given distance of 100 m, Lora gateway successfully received the packets in 80 configurations. In particular case, when the distance between node and gateway was doubled, just 8 configurations were able to deliver the packets. Finally, we used 5 values of path loss variance in range from 0 to 7.08 dB with a distance of 400 m, and the success rate of data transmission from node to the gateway decreased to 48.83%.
