Analysis of LoRa network`s QoS and QiS performance in various gateway densities

Abstract

LoRa technology is one of the recently proposed LPWAN technology. It is gaining attention of both researchers and industry. Number of connected devices through LoRa is increasing significantly year by year. Public and private LoRa networks are being deployed all continents of the world. Minimal infrastructure and maintenance cost are vital point in all deployment of LoRa network. Optimizing energy consumption while satisfying QoS demands of application will prolong lifetime of network. In this work we analyses performance of LoRa network, concerning QoS and QiS metrics, such as energy consumption and solid chemical waste from batteries in various gateway densities. We conduct two experiments to analyze how gateway density will affect QoS and QiS metrics of network performance. In first experiment we place 1 to 7 gateways and compare delay, PSR, energy consumption and chemical waste (from batteries) of network, in second experiment we perform correlation analysis of output power (2-14 dBm) and QoS, QiS metrics of the LoRa network. In first experiment best performance in terms of Packets Succes Rate is achieved in 5 gateway scenario with 96%. In the second experiment results show that properly configuring end devices` output power can decrease energy consumption.
