The Internet of Drones (IoD) is becoming foundational for collaborative aerial services in agriculture, inspection, disaster response, and logistics, where fleets must coordinate sensing, computing, and decision-making at scale. However, resource constraints on UAVs (limited energy/CPU), dynamic topologies, and latency sensitivity, as well as security threats (identity spoofing, rogue task injection, block forgery, and resource exhaustion), continue to impede reliable and large-scale deployment. We present C2B-DroneNet, a Cyber Clone-Driven Blockchain framework that unifies: (i) operation externalization, which offloads compute-intensive tasks from resource-constrained drones to fog nodes or capable peers; (ii) cyber clones, cloud-hosted predictive orchestrators that mirror drone states and proactively coordinate scheduling, failure avoidance, and routing; and (iii) a lightweight blockchain with L-PBFT consensus and elliptic-curve signatures to provide tamper-evident, low-overhead trust. Unlike prior IoD solutions that address offloading, security, or orchestration independently, this unified integration enables simultaneous resource optimization, Byzantine fault tolerance, and predictive coordination; a combination not achieved in existing frameworks. A hybrid reinforcement learning (RL) + Graph Neural Networks (GNN) decision engine exploits topology-aware embeddings and real-time telemetry to optimize offloading under mobility and deadline constraints. In simulation, C2B-DroneNet improves battery life by up to 18%, reduces latency by 68%, achieves 14% faster task completion, 12% higher throughput, and 6% higher decision accuracy relative to strong baselines. A security evaluation shows that over 99% of spoofing attempts are thwarted, malicious block forging is rejected by consensus, and deposit-reward economics suppress spam/denial-of-service (DoS). Overall, C2B-DroneNet contributes to building resilient infrastructure by unifying adaptability, computational offloading, and robust defense mechanisms for next-generation IoD environments. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.
