Abstract

This paper presents a data aggregation protocol that ensures security and reliability of aggregated data in the presence of compromised sensor nodes. The proposed protocol relies on a novel trust development algorithm which is used by data aggregators and sensor nodes to ensure the reliability of aggregated data and to select secure and reliable paths. Simulation results show that the proposed protocol improves the security and reliability of aggregated data significantly.
