Advanced Security Mechanism in Wireless Sensor Network Using Watchdog and SAFEQ Mechanism

Gajendra Singh [7] | Monali V. Ghode


Abstract: In Wireless Sensor Networks, where twotier architecture is used; the storage nodes hold the data collected bysensors acting as mediator between sink and sensors. This will help in efficient query processing in WSN. However, in reality the storage nodes are the center of attraction to attackers. Recently Chen and Liu proposed a protocol that will protect the WSN and support privacy preserving range queries. This protocol uses a novel technique for encoding data, queries and results in such a way that the whole communication is secured. In this paper we implemented a custom simulator which demonstrates the proof of concept. The empirical results revealed that the proposed security approach is effective.
