About Paper:

In resource-constrained austere environments, such as animal agriculture, the utilization of reactive hybrid topologies proves effective in addressing the challenges associated with long-range, low-power connectivity. While LoRaWAN technology offers extended coverage, it consumes considerable power, particularly with routing nodes requiring additional energy. Additionally, the ad-hoc approach commonly employed results in collisions and packet losses. To overcome these obstacles, our research introduces a novel two-way synchronized slotted approach utilizing a star-like topology. Each node is allocated a dedicated slot time, guaranteeing collision-free communication, and allowing for dynamic adaptation to varying packet sizes and sampling rates, particularly in dense clusters. In emergencies, a switch to a broadcast strategy using higher spreading factors is triggered, enabling a longer range when required. The effectiveness of our proposed approach is validated through a comprehensive evaluation encompassing various scenarios inspired by real- world conditions prevalent in animal agriculture. Both simulation and hardware testbeds are utilized to validate the performance and practicality of our solution. This research serves to adapt long-range communication to meet the unique challenges encountered in austere environments, fostering enhanced connectivity and reliability in resource-limited settings.
