LoRa-based Mesh Network for IoT Applications

In this paper, we study LoRa-based private networks for IoT applications. First, we consider the problems that may arise when LoRa devices are deployed in a private network with special operation scenarios (other than commercial networks) based on the standard LoRaWAN. We propose an improved LoRa protocol that can replace LoRaWAN. The proposed LoRa protocol overcomes the shortcomings of the existing LoRaWAN and can be effectively deployed in private networks of various applications. The proposed LoRa protocol employs mesh networking to improve the network coverage and a new multiple access scheme (other than Aloha) to reduce the data collision rate.
