摘要：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 clusterhead periodically based on the number of data-bytes sense by sensors, data aggregation, data compression and RSA, Publickey based cryptographic algorithm is used for security. Finally, proposed protocol has longer life span, better performance over security overhead and energy utilization.
