Reliable data transmission is a critical issue for wireless sensor networks. Reliable means providing security for data transmission and providing efficiency in data transmission for cluster based wireless sensor networks. Clustering is an effective and practical way to enhance the system performance of wireless sensor networks. In this paper, the clusters are formed dynamically and periodically. The Identity based digital signature protocol is introduced in order to provide reliable data transmission for cluster-based wireless sensor networks. The Identity based digital signature protocol relies on the hardness of the Diffie-Hellman problem to provide security and also it reduces the computational overhead of the protocol using discrete logarithm problem.
