Wireless Sensor Networks (WSNs) are being increasingly adopted in several fields because of their advantages with respect to classic sensor networks. However, nodes in a WSN cooperate and this exposes them to several security threats. Trust-based systems constitute an established solution to ensure security of distributed systems. In this work, a trust-based approach is discussed to make WSNs tolerant against attacks targeting their routing layer. We show how such attacks are tolerated with low overhead in comparison to unprotected systems. Preliminary experimental results are presented confirming the validity of the proposed approach.

Abstract

Wireless Sensor Networks (WSNs) are being increasingly adopted in several fields because of their advantages with respect to classic sensor networks. However, nodes in a WSN cooperate and this exposes them to several security threats. Trust-based systems constitute an established solution to ensure security of distributed systems. In this work, a trust-based approach is discussed to make WSNs tolerant against attacks targeting their routing layer. We show how such attacks are tolerated with low overhead in comparison to unprotected systems. Preliminary experimental results are presented confirming the validity of the proposed approach.
