Data aggregation and storage has become very important issue in sensor networks for future information retrieval. Storage nodes serve as an intermediate tier between sensors and a sink for storing data and processing queries in wireless sensor networks. The importance of storage nodes also makes them attractive to attackers. Data storage is happens via the forwarding nodes and storage nodes. Storage nodes are introduced in this paper to store collected date from the sensors in their proximities, it reduce the energy cost and communication cost induced by network query.
