Wireless sensor networking is an emerging technology, which potentially supports many emerging applications for both civilian and military purposes, ranging from environmental monitoring to battlefield surveillance. However, since sensor nodes are inexpensive devices, which could be easily compromised and controlled by an adversary, the compromised nodes could report false sensed results and degrade the reliability of the whole network. Therefore, how to identify these compromised nodes in a wireless sensor network is a very important security issue. To solve this problem, we propose an efficient algorithm, called AICN, to logically identify the compromised nodes in an efficient and effective way. Based on the network reliability estimation (NRE), we also present its enhanced version to further improve the efficiency.
