Data storage has become an important issue in wireless Sensor Networks (WSN) as a huge amount of collected data needed to be archived for future reference. Storage nodes are introduced here to store the data collected from the sensors in their proximities. The storage nodes alleviate the heavy load of transmitting all data to a central place for archiving and reducing the communication cost induced by the network query. This paper proposes a new security mechanism to store the data and the query processing through the secure routing in WSN, and also addresses the storage node placement, aiming to minimize the total energy cost for gathering data to the storage nodes, replying queries and level of encryption for extend the security for data communication. This paper examines the secure routing protocol for query processing and data transmission in it.
