An Efficient Top-k Query Processing with Result Integrity Verification in Two-Tiered Wireless Sensor Networks
In two-tiered wireless sensor networks, storage nodes take charge of both storing the sensing data items and processing the query request issued by the base station. Due to their important role, storage nodes are more attractive to adversaries in a hostile environment. Once a storage node is comprom...
