Abstract

Abstract Many of the Internet of Things (IoT) profit significantly from long-range connectivity with low power. Low power wide area network (LPWAN) technologies are designed to extend the coverage by minimizing the energy efficiency and less expense of data throughput. Long range WAN (LoRaWAN) is a media access control (MAC) protocol operated by the LoRa Alliance using the unlicensed LoRa radio modulation technology. LoRaWAN provides a successful innovation to meet the long–range and low-power demands. LoRaWAN offers three distinct device classes (A, B and C), providing a trade-off among effectiveness and power usage. This paper provides a comparison of these classes theoretically and the simulation of class A with reduction of duty cycle. The main contribution of this paper is to analyze the scalability of LoRaWAN and its packet deliver ratio (PDR) with maximum number of nodes. Utilizing LoRaWAN the outcomes are built up an examination of scalability and unwavering quality measure in ns-3.
