Secure Multi-Hop Data Transmission Over Cluster Based Wireless Sensor Network

In Wireless Sensor Networks (WSNs), secure data transmission is the major problem. LEACH protocols are used in wireless sensor networks which cause orphan node problem based on Security and require high Energy Consumption. Clustering technique is an effective way to enhance the system performance of wireless sensor networks. To address this problem Propose Secure and Efficient data Transmission (SET) protocols for Cluster Based Wireless Sensor Networks (CWSNs), called SETIBS (Identity-Based digital Signature) scheme and SETIBOOS (Identity-Based Online/Offline digital Signature) scheme. In the SET-IBS scheme, provide remedy for the cryptography problem in the pairing domain and used in Base Station of the Networks for security purpose. SETIBOOS scheme is reduced to computational overhead for the protocol security and provide energy consumption for nodes. The SET protocol implements for one way hash function that enhances the security and also provide random key generation algorithm. The SET-IBS and SETIBOOS protocols are used to provide the secure communication by using ID-Based Signature against attacks in the networks. These two schemes provide security and energy consumption for the Cluster based wireless sensor network.
