Security is critical aspect in two-tiered wireless sensor network and it is twofold in nature i.e. preserving privacy and integrity. To preserve the privacy, intermediate tier i.e. storage node has to process encoded queries over encoded data without knowing the actual values of sensor collected data. To do this, the authors use Prefix Membership function. To preserve the integrity of query result, they have considered two different techniques Merkle Hash Tree and Neighbor Chaining and compared the performance of these two techniques.
