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 Stickers or more LoRa end devices are placed between the source node and the destination node to act as relay nodes.

A simple routing based on the packet length is configured to determine the packet transmission path.As the results, the designed multi-hop communication could improve packet success rate until 2,47 times in 521 indoor environment.Whereas, the optimum delay time for multi-hop communication is 100 ms for each hop to produce high PRR and lowest RTT.
