W-DaM: Weather Data Management in Smart Agriculture using Blockchain-as-a-Service

Weather plays a vital role in growing and securing the yield of crops. The data collected from forecasts through different sources have been helpful in avoiding some calamities. The forecast applications are built with conventional database systems; processing and reaching real-time data without being tampered with for farmers is a bottleneck. Most of the time, weather providers' data doesn't match what happens in the farming fields. These differences can lead to heavy damage, especially during unexpected weather strikes. In the current age, smart agriculture makes use of modern equipment such as sensors and satellites that give forecasts more precisely and carefully compiled. The present paper shows an Edge hub near the IoAT device that controls all sensor devices to establish bidirectional communication and embeds Blockchain-as-a-Service (BaaS) for weather data integrity in immediate time. We present a novel architecture with algorithms for this weather data management system and implement the system to see the performance with real-time sensor data.
