| Abstract Text | In the Internet-of-Things (IoT), Low Power Wide Area Networks (LPWAN) enable IoT applications to cover large areas and operate with low energy consumption. Long Range (LoRa) Wide Area Network (WAN) is a known LPWAN technology that uses LoRa modulation on the physical layer. The performance of LoRa networks, i.e., energy efficiency, network scalability, and throughput, is typically improved with Adaptive Data Rate (ADR) algorithms. This thesis provides implementation and evaluation of State-of-the-Art (SotA) ADR algorithms in the Network Simulator 3 (ns-3) framework. The simulations revealed problems of SoTA ADRs in highly congested networks. The solutions to those problems led to the specification, implementation, and evaluation of novel ADR techniques that further improve the network performance. Several ADR schemes are compared and show that the newly developed ADR algorithms enable substantially higher network scalability, throughput, and reliability in comparison to the SotA techniques. |
