Abstract: In Wireless Sensor Networks, Traditional Aggregation Schemes were used to aggregate the ciphertext without decryption. Since it causes problems such as aggregation constraint and failure of data integrity, a new technique called Recoverable Concealed Data Aggregation was introduced. Here in this scheme, the base station can recover all the sensing data even these data has been aggregated. Such a property is called as ‘recoverable’. Also it suits well for both homogeneous and heterogeneous wireless sensor networks. In this paper, a comprehensive overview of all the supportive aggregation mechanisms was discussed briefly.
