Hybrid Low-Power Wide-Area Mesh Network for IoT Applications

The recent advancement of the Internet Things (IoT) enables possibility data collection from diverse environments using IoT devices. However, despite rapid low-power communication technologies, deployment networks still faces many challenges. In this paper, we propose a hybrid, low-power, wide-area network (LPWAN) structure that can achieve coverage and low power consumption on devices by utilizing both sub-GHz long-range radio 2.4 GHz short-range radio. Specifically, constructed mesh with LoRa, physical-layer standard provide (kilometers) point-to-point custom time-division multiple access (TDMA). Furthermore, extended capabilities enabling ANT, an ultra-low-power, protocol to satisfy in dense device deployments. Third, demonstrate performance hybrid two real-world deployments at Purdue University campus university-owned farm. results suggest have superior advantages terms cost, coverage, vis-\`a-vis other solutions, like LoRaWAN.
