Abstract:

A bucket partition based privacy-preserving top-k query processing (BPTQ) in two-tiered wireless sensor networks was proposed. BPTQ can protect the privacy of sensing data during the storage, communication and query processing by introducing bucket partitioning scheme and encryption technique. Analysis and experiments show that BPTQ can preserve the privacy of the sensing data and query result, and it is more efficient in energy consumption than the existing work.

Key words: two-tiered wireless sensor networks, privacy preserving, top-k query, bucket partition
