Security Challenges of Sensor Network Query Processor in Wireless Sensor Network

Recently, the use of the database paradigm has emerged as a feasible solution to manage data in Wireless Sensor Network (WSN) environments. Various Sensor Network Query Processors (SNQPs) implements in-network declarative query processing that provide data reduction, aggregation, logging, and auditing facilities. These SNQPs view the WSN as a distributed database over which declarative query processor can be used to program WSN applications with much less effort. This paper discusses novel approaches of SNQP in WSN from the point of security. We discuss security requirements, attack models and unique features of SNQP in WSN. Finally, we suggest security challenges of SNQP in WSN.
