Energy-Efficient and Secure UAV Next-Generation Networks with Blockchain for Revolutionary Agriculture

 Since with the growing era of modernizing culture Unmanned Aerial Vehicles based agriculture is also  increasing in demand for precisely  crop monitoring, soil analysis etc. However, this large-scale utilization of aerial vehicles  faces significant challenges in energy efficiency, data integrity and secure coordination on flight. Various traditional centralized communication models suffers from high transmission overhead and vulnerability in data transmissions. This paper researches for the novel idea of  energy-efficient, blockchain-enabled UAV network architecture that ensures secure data exchange, with decentralized optimised communication. Though it is hybrid edge-blockchain with adaptive routing, it minimizes energy consumption of aerial vehicles which also impacts on longevity in the farming field. Experimental results demonstrate a 25–35 % reduction in energy , 20–27 % improvement in mission time. It also shows latencies  and packet-loss that supports revolutionary agriculture operations such as precision irrigation, autonomous spraying, yield prediction and carbon-efficient farming laying the foundation for next-generation sustainable smart agriculture networks.
