A secure and energy-efficient fog-integrated UAV surveillance framework using IntelliGuard and DPAFIO
摘要
Unmanned Aerial Vehicles (UAVs) are dramatically rising in terms of border surveillance, but with a low battery capacity, significant communication overhead, and prone to node compromise, it is hard to apply it to large scale deployments. This article presents a dual layer secure and efficient drone-based surveillance system that incorporates multi-cluster communication, Fog Computing (FC), and trust-based authentication. A Dual Phase Adaptive Fusion Intelligence Optimizer (DPAFIO) is proposed to find out Cluster Heads (CHs) based on residual energy, trust score and positional efficiency, and to evenly distribute the work load and stabilize the cluster formation. Each cluster is provided with a load-adaptive group of cooperative CHs, serving to distribute workloads, provide redundancy, and failover in a short time, and member drones transmit to the nearest CH to minimize range of transmission and energy loss. A Fog layer, between the cloud and the drone network carries out the in-network aggregation and early-decision-making that decreases the latency and the transmission over long distances. Dynamic trust score-based validation mechanism is used in order to identify the compromised nodes before passing on the data. The results of the simulation indicate that the proposed framework is efficient and stable. The evaluation is based on 30 independent simulation runs across 50 rounds. The average energy consumed is 0.8133
