XU Jiana · Jisuanji gongcheng · 2012
The special characteristics of Wireless Sensor Network(WSN),such as resource constraints and self-organizing nature of its architecture,introduce unique challenges for privacy preservation in WSN.The privacy-preserving aggregation techniques are classified into three categories: cluster-based,slice-based and encrypt-based depending on the protocol operation.It reviews the existing techniques for privacypreserving data aggregation,including CPDA,iCPDA,SMART,ESPART,CDA,RCDA,KIPDA and so on,evaluates their performances in terms of several metrics,such as computation complexity,communication complexity,delay,privacy,accuracy,and then summarizes the pros and cons of each algorithm.Some important future research directions in the field of privacy-preserving data aggregation for WSN are discussed.
