The topic of privacy preservation in Wireless Sensor Networks (WSNs) has attracted many research studies during past few years. Two types of privacy have been discussed in the literature; data-oriented privacy and context-oriented privacy. This paper introduces the concept of rate privacy in the context of wireless sensor networks. The authors' discussion reveals that the concept indeed is of a great importance for the privacy preservation of such networks. As a result, they propose a buffering scheme to protect the rate from adversaries. Simulation results verify the applicability of their approach.
