Abstract
Low Power Wide Area Network is one of the leading technologies for the Internet of Things. The capability to scale is one of the advantage criteria for a technology to compare to each other. The technology uses a star network topology for communication between the end-node and gateway. The star network topology enables the network to support a large number of end-nodes and with multiple of gateways deployed in the network, it can increase the number of end nodes even more. This paper aims to investigate the performance of the Low Power Wide Area Network Technology, focusing on the capability of the network to scale using multiple gateways as receivers. We model the network system based on the communication behaviours between the end-node and gateways. We also included the communication limit range for the data signal from the end-node to successfully be received by the gateways. The performance of the scalability for the Low Power Wide Area Network Technology is shown by the successfully received packet data at the gateways. The simulation to study the scalability was done based on several parameters, such as the number of end-nodes, gateways, channels and also application time. The results show that the amount of successfully received data signal at gateway increased as the gateways, application time and channel used increased.
Highlights
For the past few years, the advances in the development of Internet-of-Things (IoT) speed up the growth for new, innovative, convenience, and economic benefit applications
The development and simulation of a comprehensive model of Low Power Wide Area Network (LPWAN) to study the scalability using MATLAB simulator is presented. This model includes several assumptions based on the behaviour of LPWAN communication between the end-nodes and gateways, such as the interference conditions of data signal and the selection of the Spreading Factor and the application time
The results show that increasing number of end-nodes, decreases the www.ijacsa.thesai.org value of percentage of received packet data (PPD)
Summary
For the past few years, the advances in the development of Internet-of-Things (IoT) speed up the growth for new, innovative, convenience, and economic benefit applications. The technology inspired by IoT is believed to be able to enhance the effectiveness of energy consumption, resources management, productivity, and environmental monitoring. The IoT has spread its importance to various domains which previously has a limitation in multiple possible applications, for example, real-time environmental, remote health-care, industrial control, productions systems, smart city, and transportation [2]. Traditional short-range communication technologies such as Bluetooth and ZigBee are not ideal for applications that require long-range communication. While cellular technology can provide broader coverage than conventional radio technology, it requires much energy to operate, which is not ideal for low power applications
