Abstract—In the last decade, the Internet of Things (IoT) technologies have brought many applications in different fields. Many
communication technologies have been developed to communicate everything to each other and the Internet. Besides, the long-range
power-efficient wireless technologies have emerged, such as LoRa (Long Range), which enables transmission over long distanceswith low energy consumption and can work within p2p, star, or mesh topologies. In this paper, we analyze a model of a meshnetwork based on the LoRa technology. The model considers various parameters of nodes and communication channels in thenetwork. Based on a simulation model on OMNET++, a series of computer experiments are performed to analyze the delivery
latency and packet delivery ratio (PDR) in different cases. According to the analytical results, conclusions are drawn about thepossibility of using a LoRa mesh network to expand the network coverage and integrate with other short-range networks.
Keyword— IoT, LoRa, mesh network, routing method, latency, packet delivery ratio
