Enhanced Data Transmission in Cluster Based Wireless Sensor Networks
R Rasoolbee, M Manjula · 2015
Wireless Sensor Networks are tiny devices that are deployed in various environments with less security. Providing security for the Wireless Sensor Networks is difficult while transmission of data to each other in the network. Clustering, a technique in which all the sensor nodes are binded together to form a group of clusters with a Cluster Head to aggregate data from the sensor nodes and then send the data to the Base station. Two protocols for providing security to Cluster Wireless Sensor Networks while transmitting data are SET-IBS and SET-IBOOS. The two proposed protocols uses Identity based cryptography for symmetric key encryption to solve the orphan node problem and increases the performance of the Cluster Wireless Sensor Networks when compared with the existing protocols. Proposed protocols are compared with other clustering protocols for performance metrics like number of alive nodes, system life time and energy consumption. SET- IBS and SET-IBOOS protocols provide security based on Diffie Hellman and Discrete logarithm problems.
