ABSTRACT

According to researches, the wireless sensor networks which consume low levels of energy will soon be widely deployed, so the research trend of optimizing power consumption for wireless sensor networks is increasing As of today, major problem in deploying wireless sensor networks is their dependence on limited battery power

LoRaTM technology is a modulation technique that enables the long-range transfer of information with a low data rate Besides, LoRaWANTM is a network protocol which is optimized for battery-powered end devices The LoRaTM and LoRaWANTM can be considered a suitable candidate in addressing the IoT challenges

In the thesis, LoRaTM and LoRaWANTM will be studied and evaluated to propose a solution for optimizing energy consumption in wireless sensor network The solution is based on ADR feature of LoRaWANTM to optimize energy consumption on sensor nodes

In addition, the thesis also demonstrates a set of solutions for deploying a LoRaTM and LoRaWANTM based IoT system which including:

- A battery-powered sensor node, which will collect air quality information and send to a LoRaTM gateway

- A LoRaTM gateway, which will receive data from sensor node and forward to LoRaWANTM server

- A LoRaWANTM server runs LoRaWANTM stack version 1.1, which will process data and implement energy-optimized solution
