Wireless sensor networks extend people's ability to explore, monitor, and control the physical world. Wireless sensor networks are susceptible to certain types of attacks because they are deployed in open and unprotected environments. Novel intrusion tolerance architecture is proposed in this paper. An expert intrusion detection analysis system and an all-channel analyzer are introduced. A proposed intrusion tolerance scheme is implemented. Results show that this scheme can detect data traffic and re-route it to a redundant node in the wireless network, prolong the lifetime of the network, and isolate malicious traffic introduced through compromised nodes or illegal intrusions.
