Deploying Storage Node Aiming to Minimize the Communication Cost of Sink in Sensor Networks
Data storage has became very important issue in Sensor networks for future information retrieval. Data Storage is happens via the Forwarding nodes and Storage nodes. Forwarding nodes are regular sensors and they always forward the data received by other nodes or generated by themselves along a path toward the sink. Storage nodes are much larger capacity than the regular sensors. They store all the data received by other nodes or generated by themselves. The sink itself considered as a storage node. 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.
