Protokol pre komunikáciu medzi uzlami siete LoRa

Abstract

LoRa technology is currently one of the most promising for IoT and is gaining a lot of attention. However, there are limitations in current applications due to the LoRaWAN specification used, which uses a star topology. LoRaWAN-based networks typically have limited scalability due to the use of a centralized management strategy. Recent advances in various LoRa mesh network designs may present a potential solution to these limitations. In this work, we address the design and implementation of a protocol that enables communication between LoRa network nodes using a mesh topology. The protocol developed in this thesis focuses on real time communication through LoRa technology and as a demonstration an application has been developed primarily intended for chat communication between users in a mesh network. However, sensor nodes can also be part of the network, sending data from the sensors to the network.
