Recent Advances of Secure Clustering Protocols in Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) have been employed in many real-world applications that greatly improve our life. The ubiquitous WSNs make security a prime issue, and new technologies have been developed recently. In this article, we review the most recent secure clustering protocols in WSNs. We start with a description of the security requirements for WSNs and discuss the existing security schemes. We analyze to what extend they have been applied to the clustering structure of WSNs. Then, we review secure clustering protocols in emerged recent years. Finally, we present a set of criteria which must be applied to build a secure clustering algorithm.
