In Wireless Sensor Networks (WSNs) sensors are constrained in battery power, communication, and computation capability; therefore, reducing the power consumption is a critical concern for a WSN. Recently, a practical solution called data aggregation is introduced. By performing data aggregation the authors can reduce the number of packets transmitted to the base station resulting in conservation of energy and bandwidth. In this paper, they are going to recover the concealed data aggregation for reliability and data integrity in wireless sensor networks where a base station can recover each sensing data generated by all sensors even if these data have been aggregated by cluster heads.
