Abstract: Wireless sensor network uses a large number of sensing nodes to collect real-time data of the deployed environment, and then send these data to the base station. For limited resources and energy, we have to consider the energy consumption problem in practical applications. In addition, data aggregation protocols need privacy protection. We have found out the high energy cost issue of the basic privacy-preserving data aggregation protocol and introduce two novel elements into the basic protocol: mobile sink and straw-man structure. Combining these two novel elements, we propose the new energy-saving privacy-preserving data aggregation protocol. In the basic protocol, the sensor nodes in each sensing period need to receive and send multiple ciphertexts. While in our proposed new protocol, the sensor nodes in each sensing period only need to send a ciphertext. Therefore, our protocol can reduce the energy consumption of the whole network and prolong the service life of wireless sensor networks.
