Data Based-Secure and Efficient Dynamic Clustering (DB-SEDC) for Data Aggregation in Wireless Sensor Network

Abstract: Secure and efficient data aggregation is very critical task in wireless sensor network. To overcome this problem, in this paper, we have proposed cluster-based WSN, where clusters are formed dynamically and periodically. And also cluster-head is elected dynamically. We propose a protocol called DB-SEDC (Data Based-Secure and Efficient Dynamic Clustering); which is having the capability of electing cluster-head periodically based on the number of data-bytes sense by sensors, data aggregation, data compression and RSA, Public-key based cryptographic algorithm is used for security. Finally, proposed protocol has longer life span, better performance over security overhead and energy utilization
