A study of Intrusion-tolerant routing in Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) emerge recently as one of the most attractive research subjects. The resource- constraint characteristics of WSNs limit the secure design and development of security protocols for them. Whilst, sensor nodes those usually operate in unattended and even harsh environments, are prone to failures and are vulnerable to malicious attacks. For reliable and secure communications in WSNs, intrusion-tolerant routing becomes a critical attribute that should be integrated into WSNs. In this paper, we study two intrusion- tolerant routing protocols for WSNs, namely INSENS and ITSRP, as well as analyze the intrusion-tolerant properties gained from these two propositions. Simulation and performance analysis have proved that both of them are practical.
