Authentication mechanism based on distributed blockchain for secure and energy efficient mobile ad-hoc networks

Area of Science:

• Computer Science
• Network Security
• Wireless Communication

Background:

• Mobile Adhoc Networks (MANETs) face significant security challenges.
• Existing MANET security solutions are often centralized and power-intensive.
• There is a need for decentralized, energy-efficient security mechanisms in MANETs.

Purpose of the Study:

• To propose a novel technique, DBlock-Auth, for enhancing security in MANETs.
• To achieve high security levels with minimal energy consumption.
• To improve overall network performance metrics.

Main Methods:

• DBlock-Auth technique divides networks into zones and clusters based on Similarity Score (Sim-Score).
• Nodes are authenticated using Blockchain-based Physical Unclonable Functions (BPUF).
• Cluster Heads (CH) are selected using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), and data transfer paths are optimized using MuMoT.
• Light HB technique ensures data security.

Main Results:

• Simulations using ns-2 network simulator evaluated Quality of Service (QoS) parameters.
• The DBlock-Auth technique demonstrated superior security levels.
• Improved Packet Delivery Ratio (PDR), energy efficiency, reduced latency, and enhanced throughput were observed.

Conclusions:

• The DBlock-Auth technique effectively addresses MANET security issues.
• The proposed method offers a balance between high security and low energy usage.
• The results validate the efficiency and effectiveness of the DBlock-Auth technique in MANETs.
