Efficient Secure Routing Mechanism in MANET Using Trust Model

Overview & Implementation

This case study highlights the research assistance provided by TEQ Research Solution for a Ph.D. research project titled “Efficient Secure Routing Mechanism in MANET Using Trust Model” in the field of Mobile Ad Hoc Networks (MANET), Secure Routing, and Trust-Based Communication Systems. The research focused on developing a novel trust-aware routing framework called STBRA (Secured Trust Based Routing Algorithm) to improve secure packet transmission, malicious node detection, throughput performance, and routing efficiency in MANET environments.

Problem Statement

Mobile Ad Hoc Networks (MANETs) are infrastructure-less wireless communication systems with highly dynamic topology and node mobility. Existing routing methods faced several challenges including:

·         Frequent link failures

·         Routing attacks

·         Packet loss

·         Poor throughput

·         High routing overhead

·         Increased end-to-end delay

·         Energy consumption issues

·         Low malicious node detection rate

·         Poor packet delivery ratio (PDR)

Existing trust-based routing techniques such as:

·         TDSR (Trusted Dynamic Source Routing)

·         TAODV (Trusted Ad hoc On-Demand Distance Vector)

·         TOLSR (Trusted Optimized Link State Routing)

·         TACO (Trusted Ant Colony Optimization)

·         Fuzzy-FPSO

primarily focused on throughput and delay optimization but lacked effective secure routing mechanisms and trust evaluation models.

Proposed Solution

TEQ Research Solution assisted in developing a novel routing framework called:

STBRA – Secured Trust Based Routing Algorithm

The proposed STBRA framework was designed to:

·         Provide trusted and secure routing

·         Detect malicious nodes effectively

·         Improve packet delivery ratio

·         Reduce routing overhead

·         Minimize end-to-end delay

·         Enhance network throughput

·         Optimize residual energy utilization

·         Improve secure communication in multi-hop networks

The algorithm dynamically selected trusted paths using:

·         Trust Value Calculation

·         Huddle Formation

·         Huddle Head Election

·         Optimal Route Selection

·         Bayesian Trust Verification

·         Artificial Fish Swarm Optimization

The framework ensured secure routing through trusted huddle head nodes while minimizing communication overhead.

Key Phases of STBRA

The proposed STBRA algorithm consisted of four major phases:

1.      Huddle Formation

2.      Huddle Head Election

3.      Trust Value Calculation and Updating

4.      Optimal Route Selection

The algorithm divided the MANET environment into multiple huddles (zones) to simplify trust calculation and improve secure communication efficiency.
