Hierarchical Processing of Signals for Smart Crop Monitoring*

Smart crop monitoring is a new concept for different modern agricultural research and production management. The paper presents a hierarchical structure of data processing from the sensors used in crop monitoring. The proposed system consists in the integration of multi WSN network at ground level, a team of UAVs at aerial level, with the mission of both direct data acquisition and data collecting from WSN. The information from UAV is next transmitted to a central data analysis and interpretation via internet. To this end, a multi levels data processing structure is proposed: in field processing, fog computing processing and cloud computing processing. The design of an efficient UAV trajectory for collecting of data and obstacle avoidance and, also, a model of intelligent data processing and transmission are proposed.
