The current research work in wireless sensor networks has mostly focused on the resolving issues related to power consumption and computational resource constraints in the wireless sensor networks. To achieve the same various specific routing schemes, MAC and cross layered protocols and techniques have been proposed and designed. But with recent advances the privacy issues related to the data collected and transmitted by the wireless sensor networks had taken the center stage. Privacy preservation in wireless sensor networks has become more challenging because of the wireless nature of communication in WSN as well as its self organizing architecture.
