Wireless sensor network security enhancement
Team-led WSN hardening using scale-free modeling and the ROSE algorithm, demonstrating improved robustness over existing approaches.
- Role
- Project Lead — Ball State University (undergraduate), 2019
- Stack
- Python, NetworkX, graph algorithms, security modeling
Highlights
- Led the team enhancing WSN resilience against attacks on critical nodes.
- Modeled scale-free topologies and applied ROSE to reorganize edges into an onion-like robust structure.
- Showed improved robustness versus prior industry baselines under the same threat model.
Problem
Wireless sensor deployments in adversarial settings can collapse if a few high-value nodes are compromised; the team needed a principled topology strategy rather than ad hoc hardening.
Approach
Combined scale-free graph modeling with the ROSE ranking approach to iteratively rewire edges toward layered defense depth, then evaluated the structure against representative attack patterns.
Outcome
Demonstrated improved robustness over existing approaches with a clear graph-theoretic narrative suitable for academic defense.
Technical notes
- Reproducible graph generation seeds for fair comparison runs.
- Visualizations of before/after centrality profiles for reviewers.
