Multi-hop Communication between LoRa End Devices

Gateway elimination in a LoRa network could highly reduce the network installation cost.However, LoRa end devices could not overcome many obstacles with only a point-to-point communication.Thus, this research implemented a multi-hop communication in a LoRa network.One or more LoRa end devices are placed between the source node and the destination lunchbag node to act as relay nodes.A simple routing based on the packet length is configured here to determine the packet transmission path.

As the results, the designed multi-hop communication could improve packet success rate until 2,47 times in indoor environment.Whereas, the optimum delay time for multi-hop communication is 100 ms for each hop to produce high PRR and lowest RTT.
