A comprehensive study of node replication attack in wireless sensor networks

The adversary can get benefit from the unattended nature of Sensor Networks to physically capture the sensor node, compromises the node and extracts the contents from node and clone them in many replicas. This paper attempts to comprehensively review the current research and schemes for the detection of node replication attack. In order to evaluate the maturity level of the top current scheme in replication detection, a set of significant features, that best describe the functionality and the characteristics of the schemes, has been selected to derive a comprehensive study. The aim of this survey is not to censure, but to serve as a reference for researchers and developers in this area and to provide direction for future research improvements. This paper also classifies proposed schemes into Distributed and Centralized according to their nature of defense. The complexities of communication & memory cost for both types of scheme are also evaluated.
