Internet of Things Software Defined Radio Technology for LoRaWAN Wireless Communication: A survey

The past few years we have witnessed an increase in the development of IoT concept. This concept entails the connection of objects that surround us in our everyday life to Internet. This paradigm where the human users are replaced by objects determines the appearance of different problems that are related to: scalability of the systems and sensors, power supply management techniques that must allow the sensor to operate for years and even decades and longer communication range suitable for urban non-LoS. LoRa modulation among the LoRaWAN communication protocol is regarded as a problem solver. In this paper, we present the development and the design of a LoRa traffic generator that has the ability of generating a high volume of traffic. This approach allows for the emulation of large scale LoRaWAN networks without the need of additional costs. Thus, the scalability and the reliability of LoRa networks can be researched and studied in detail. From the obtained results the LoRa traffic generator ensures a high level of performance and can be used for future improvements of LoRa communication.
