This research work proposes a Distributed Blockchain-Assisted Secure Data Aggregation (Block-DSD) technique for MANETs, ensuring high security and energy efficiency in disaster management scenarios. A Zone-based Clustering Approach (ZCA) is employed to segment the network into secure zones, with optimal Cluster Heads (CHs) selected using Artificial Neuro-Fuzzy Inference System (ANFIS). aggregation secured through Two-Step (STS) method Elliptic Curve Cryptography (ECC), while routing achieved Improved Elephant Herd Optimization (IEHO) algorithm. Simulations ns-3.25 demonstrate 97% Packet Delivery Ratio (PDR), 20% lower consumption compared existing methods, minimal latency of 0.0012 s emergency data, validating proposed framework's robustness dynamic MANET environments.

The Internet of Things (IoT) is a disruptive technology that underpins Industry 5.0 by integrating various service technologies to enable intelligent connectivity among smart objects. These enhance the convergence Information Technology (IT), Operational (OT), Core (CT), and Data (DT) networks, improving automation decision-making capabilities. While cloud computing has become mainstream across multiple domains, it struggles efficiently manage massive volume OT data generated IoT devices due high latency, transfer costs, limited resilience, insufficient context awareness. Fog emerged as viable solution, extending capabilities edge through distributed peer-to-peer (P2P) network, enabling decentralized processing management. However, networks still face critical challenges, including connectivity, heterogeneity, scalability, interoperability, security, real-time constraints. Security key challenge in implementations, secure communication, fog device identity, end-to-end authentication, storage. This paper presents an efficient blockchain-based framework creates communication cooperative flow network. utilizes hybrid blockchain network collaborates offer collaborative from end servers will maintain private next-generation public infrastructure identify authenticate IoT's devices. consortium be maintained integrated with permission system. system ensures storage, authorization, exchange, remote protection (encryption) all sensitive information. To improve synchronization block generation, reduce overhead, ensure scalable operation, we proposed threshold signature-based Proof Stake Validation (PoSV) consensus. Additionally, lightweight authentication protects resource-constrained nodes using aggregate signature, ensuring security performance scenarios. implemented, its evaluated metrics such cryptographic consensus efficiency, acceptance time, transaction delay. findings show consensus, reduces computational burden individual signature verification, which results optimized latency 80–150 ms, compared previous 100–200 ms without Non-PoSV. aggregating signatures different events signing time 1.98 2.72 overhead verifying transactions 2.87 significantly reduced to1.46 along delay ranges between 95–180 ms. Hence, improves over existing approaches regarding linear complexity, increased methods, more process.
