Privacy preservation in wireless sensor networks has drawn considerable attention from research community during last few years. Emergence of single-owner, multi-user commercial sensor networks along with hostile and uncontrollable environ- ment of such networks, makes the security issue in such networks of a great importance. This paper concentrates on token-based privacy preservation schemes. A possible attack on such schemes is introduced and two different approaches are utilized to mitigate the attack. Mathematical models for considering the attack effect and overhead are presented and the results are verified using extensive simulations.
