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.
