Centralized Communication Scheduler for LoRa

The Internet of Things became increasingly popular in a variety of fields. This environment involves interconnected devices connected to the internet, which can transmit data and receive commands. To satisfy requirements such as long communication range and low power consumption, Low-Power Wide-Area Networks can be used. Wireless communications are known for being prone to collisions, which result from the simultaneous transmission of multiple devices. Collisions affect reliability and cause data corruption and retransmissions. Collisions thus influence network reliability and scalability, which are important parameters. To overcome this problem, a variety of collision avoidance and medium access techniques have been proposed. This paper focuses on a more effective solution and presents a centralized scheduler for communication coordination in the LoRa network.
