Manipulation and Analysis

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Area of Science:

  • Computer Science
  • Network Security
  • Mobile Computing

Background:

  • Mobile Ad-hoc Networks (MANETs) face significant security and energy challenges, especially in critical disaster management scenarios.
  • Existing data aggregation techniques often lack robust security or are energy-intensive, limiting their effectiveness in dynamic environments.

Purpose of the Study:

  • To propose a Distributed Blockchain-Assisted Secure Data Aggregation (Block-DSD) technique for MANETs.
  • To enhance security, energy efficiency, and data reliability in disaster management operations within MANETs.

Main Methods:

  • A Zone-based Clustering Approach (ZCA) was used to segment the network into secure zones.
  • Optimal Cluster Heads (CHs) were selected using the Artificial Neuro-Fuzzy Inference System (ANFIS).
  • Data aggregation was secured using a Two-Step Secure (STS) method combined with Elliptic Curve Cryptography (ECC), and routing was optimized with the Improved Elephant Herd Optimization (IEHO) algorithm.

Main Results:

  • The Block-DSD technique achieved a 97% Packet Delivery Ratio (PDR).
  • Demonstrated a 20% reduction in energy consumption compared to existing methods.
  • Achieved minimal latency of 0.0012 seconds for emergency data transmission.

Conclusions:

  • The proposed Block-DSD framework is efficient and robust for secure data aggregation in dynamic MANET environments.
  • The integration of blockchain, ANFIS, ECC, and IEHO significantly improves network performance and security for disaster management.
  • The results validate the practical applicability of the technique in real-world emergency scenarios.
