Paper Abstract

With the increasing popularity of wireless sensor networks (WSNs) for the daily operations in both commercial and defense sectors, designing an efficient and secure query processing mechanism becomes critical to returning a reliable data response to the user in a timely manner. While recent research efforts on database based query processing dramatically improves the efficiency of query processing, another critical component, security, is still in its early stage of development. The intent of this work is to develop an efficient trust-aware querying mechanism to identify the trustworthiness of sensor nodes, while simultaneously filtering out bogus data in the querying process. Our final goal is to return the highest-fidelity data response to the user while monitoring the health of the network by flagging suspected compromised nodes. It is noted that the proposed trust-aware querying mechanism does not eliminate the utilization of any conventional cryptographic approaches, and it works as a complementary component to provide an advanced security solution with the imperfect WSN of today.
