A Survey on Secure and Efficient Data Transmission for Cluster-Based Wireless Sensor Networks (CWSN)

Secure data broadcast is a severe problem for wireless sensor networks (WSNs) so the clustering is an efficient and realistic method to get better system performance of WSNs. This paper discussed the secure data broadcast for cluster-based WSNs (CWSNs) where the clusters are created dynamically and periodically. The two proposed Secure and Efficient data Transmission (SET) protocols used in cluster-based WSNs [1] are SET-IBS and SET-IBOOS with the Identity-Based digital Signature (IBS) method and the Identity-Based Online/Offline digital Signature (IBOOS) method, respectively. In SET-IBS, security depends on the rigidity of the Dife-Hellman problem in the coupling domain. The SET-IBOOS additionally minimize the computational burden for protocol security, which is crucial for WSNs, at the same time as its security depends on the rigidity of the discrete logarithm problem. This paper shows the practicability of the SET-IBS and SET-IBOOS protocols regarding the security requirements and security analysis beside a variety of attacks. The result shows the efficiency of the proposed protocols. In the terms of security overhead and energy consumption, the outcome of the proposed protocols have enhanced performance than the existing secure protocols for CWSNs, In this paper, we discussed a secure data transmission for cluster-based WSNs in which the clusters are formed dynamically and at regular intervals.
