| Abstract Text | This bachelor-thesis tries to incorporate Software Defined Networking (SDN) mechanisms into a Long Range (LoRa) Internet of Things (IoT) mesh. Typically, devices used in LoRa-based wireless sensor networks (WSN) are limited in range. Therefore, in a scenario where a significant amount of nodes would be out of range of the LoRa Wide Area Network (LoRaWAN), deploying a mesh topology is a simple yet effective way to connect far away nodes using multi-hop communication. SDN, on the other hand, aims to improve network performance by analyzing the network and applying smart optimization algorithms. The hardware used in this thesis, are nodes being a Raspberry Pi, a popular choice inIoT, and the E32-868T20D LoRa Shield, a budget-friendly option to adapt LoRa technology. The software is implemented in Java, a programming language that promotes human-readability in code and benefits from decades of experience in practical software development. While LoRa networks with mesh topologies have already been subject of previous research using various devices and programming languages, the goal of this thesis is to test the effectiveness of SDN-based mechanisms in improving a LoRa mesh network and finally providing a user-friendly API as a service to other applications as a transmitter of data. Disclaimer: Neither the product, nor the analysis of SDN-based mechanisms have reached a state of success. |
