Abstract

Abstract The Agro-gain provides an end-to-end lot platform for data-driven agriculture, that gives an seamless data collection from various sensor type like drones, cameras and sensors. Agro-gain can ensure the availability of system even when the power and internet outages caused by bad weather. First, to enable connectivity within the farm, Agro-gain leverages recent work in unlicensed TV White Spaces (TVWS) to setup a high band width link from the farmer’s home Internet connection to an IoT base station on the farm. Sensors, cameras and drones can connect to this base station over a Wi-Fi frontend. This ensures high bandwidth connectivity within the farm. However, due to the lack of power on the farm, the base station is powered by battery- backed solar power which suffers from power unreliability depending on weather conditions. As shown in past work, cloudy weather can reduce solar power output significantly and drain the batteries of the base station to shut it down. To solve this problem, Agro-gain uses a novel weather-aware IoT base station design. Specifically, it uses weather forecasts to appropriately duty cycle different components of the base station. To the best of our knowledge, this is the first weather-aware IoT base station design. Second, internet connection to the farm is typically weak and it is not sufficient to ship high bandwidth drone videos to the cloud. The Agro-gain uses a Gateway based design, where in a PC at the farmer’s home serves as a gateway for the farm data.
