Sensor network history suggests that clustering is one of the most effective techniques to increase the performance of deployed wireless sensor networks. But along with the implementation of clustering in WSNs; it is necessary to resolve numerous challenges like secure and efficient data transmission, providing high-level security against variety of security attacks and aggregation of data. It is a challenging task to address all the challenges using a single framework or protocol. However, already few schemes like Sec-Leach, SET-IBS and SET-IBOOS have been proposed to resolve this issue but due to invention of new attacks security has always remained an unresolved issue.
