TrustSense: An energy efficient trust scheme for clustered wireless sensor networks
Adedayo Odesile, Brent Lagesse

TL;DR
TrustSense is a reputation-based security protocol for clustered wireless sensor networks that improves energy efficiency and reliability by combining trust updates, spatial correlation, and packet validation at cluster-heads.
Contribution
It introduces a semi-centralized reputation management protocol that reduces energy consumption while maintaining security in resource-constrained sensor networks.
Findings
Significant energy savings compared to legacy systems
Improved reliability in the presence of malicious nodes
Maintains acceptable path length with fewer energy resources
Abstract
Designing security systems for wireless sensor networks presents a challenge due to their relatively low computational resources. This has rendered many traditional defense mechanisms based on cryptography infeasible for deployment on such networks. Reputation and anomaly detection systems have been implemented as viable alternatives, but existing implementations still struggle with providing efficient security without a significant impact on energy consumption. To address this trade-off between resource consumption and resiliency, we designed TrustSense, a reputation management protocol for clustered WSNs. It is a semi-centralized family of algorithms that combine periodic trust updates, spatial correlation, and packet sequence validation at the cluster-heads' hierarchy to relieve the sensor nodes of unnecessary opinion queries and trust evaluation computation. We compared the…
