In the past few years secure transmission of data along with efficiency is a critical issue for Wireless Sensor Networks (WSNs). Clustering is an effectual and convenient way to enhance performance of the WSNs system. In this paper, the authors study a secure transmission of data for Cluster-based WSNs (CWSNs), where the clusters are formed dynamically and sporadically. They make use of two Secure and Efficient data Transmission (SET) protocols for CWSNs, called SET-IBS and SET-IBOOS, by means of the Identity-Based digital Signature (IBS) scheme and the Identity-Based Online/Offline digital Signature (IBOOS) scheme, correspondingly.
