Optimized Communication Model for IoT Network Using LoRaWan

Abstract

In today’s world concept of internet of things is emerging rapidly and high demand of IOT requires a communication standard that can provide lower power consumption, long coverage area and scalability. Some of the communication standards including cellular, wireless sensor or Bluetooth cannot provide these requirements as a package, so to counter these issues LoRaWan is the protocol. Key feature of LoRaWan is that it can provide communication at longer distances with lower power consumption that is ideal in the concept of IOT network. In this study we are going to analyze the performance of LoRaWan in outdoor and indoor scenarios conditions, which will give directions in implementation of network using LoRaWan as a communication standard between the sensor nodes in different scenarios. We will deploy multiple nodes and gateways in different real world created scenarios and test their performance indicators by manipulating spreading factor and distance between end LoRa nodes and gateways. Study was conducted at SEECS building, school of electrical and computer engineering NUST, Pakistan. This study will provide comprehensive picture of desired deployment of the LoRaWan in IOT network to ensure seamless long distances communication. We manipulated the spreading factor from low to high (SF 7 to SF 12) in different outdoor and indoor scenarios to analyze the changes in RSSI, SNR which will ultimately help in the designing of IOT network or wireless sensor network for future. After analyzing the factors optimized placement of infrastructure will be proposed to achieve optimized performance, LoRaWan in internet of things.
