摘要：In the Internet of Things (IoT), a gateway and a set of IoT devices (IoTDs) form a star-topology and the IoTDs compete between them for sending uplink communication during short time slots. Therefore, in this paper, we propose a novel multiple access protocol with time-slot reservation that can increase the success rate of the uplink data transmission with collision avoidance in the IoT. Further, using a modem calculator tool from the LoRa Alliance, we evaluate the system performance of the low power wide area network which is designed for sensors and applications in terms of equivalent bitrate, time on air, and Tx energy consumption for the uplink of the IoTDs.
