Description Privacy protection problem in wireless sensor networks has drawn a lot of attention in recent years. Yet, the existing privacy protection mechanisms are not likely to bring an optimal privacy/cost trade-off for real networks. They target a specific attacker model and static application scenario requirements. However, both the attacker model and the requirements may evolve during the network lifetime. We propose a multilevel privacy protection framework that allows for a dynamic adjustment of the privacy/cost trade-off. We give concrete examples of five privacy levels each targeting a different attacker model in a given application scenario. The privacy levels deploy both existing and novel privacy protection mechanisms. We also introduce our scheme that enables a dynamic privacy level interchange. All the proposed privacy levels support a concurrent operation of a network intrusion detection system.
