Description

Secure data transmission is a critical issue for wireless sensor networks (WSNs). Clustering is an effective and practical way to enhance the system performance of WSNs. Proposed a CRP for secure data transmission for cluster-based WSNs (CWSNs), where the clusters are formed dynamically and periodically. CRP uses digital signature (DSI) scheme and the identity-based online/offline digital signature (DSOO) scheme, for security. In DSI security relies on the hardness of the Diffie-Hellman problem in the pairing domain so that it uses the hashing technique for signing and verification. In DSOO it reduces the computational overhead for protocol security, which is crucial for WSNs, while its security relies on the hardness of the discrete logarithm problem. To improve the performance if the system Energy aware Rule based scheme was proposed. Simulation results shows that proposed system has better performance compared with the existing system in terms of security, efficiency, energy consumption.
