The long-range and low energy consumption requirements in Internet of Things (IoT) applications have led to a new wireless communication technology known as Low Power Wide Area Network (LPWANs). In recent years, the Long Range (LoRa) protocol has gained lot attention one most promising technologies LPWAN. Choosing right combination transmission parameters is major challenge LoRa networks. LoRa, an Adaptive Data Rate (ADR) mechanism executed configure each End Device's (ED) parameters, resulting improved performance metrics. this paper, we propose link-based ADR approach that aims EDs by making decision without taking into account history last received packets, relatively space complexity approach. study, present four different scenarios for assessing performance, including scenario where mobile are considered. Our simulation results show with high channel noise, our proposed algorithm's Packet Delivery Ratio (PDR) 2.8 times outperforming original 1.35 other relevant algorithms.
