IMPROVISATION OF PERFORMANCE IN CLUSTER NETWORKS

Abstract

Recently identity-based digital signature has been made available as a key management in wireless sensor networks for security. We study effective data transmission meant for cluster-basis sensor system, in our work in which clusters are created dynamically and intermittently. We aim to study the proposals regarding two Secure and Efficient data Transmission procedures for cluster-based wireless sensor networks known as secure and effective data transmission-Identity-based on digital signature and secure and effective data transmission-based on online/offline digital signature. Data transmission protocol based on Identity based online/offline digital signature is projected to further decrease computational overhead for security by means of secure and effective data transmission-based on online/offline digital signature in which security depends on hardness of discrete logarithmic complexity. Identity-based protocol of digital signature on basis of complexity of factoring integers from cryptography of identity-basis is to obtain an entity’s public key from its identity information. The important notion of proposed data transmission protocols is to authenticate encrypted sensed data, by means of application of digital signatures which are efficient in communication. Both of these schemes totally work out orphan-node problem from using symmetric key management for cluster-based wireless sensor system.
