Sensor Network
A sensor network consists of multiple detection
stations called sensor nodes, each of which is
small, lightweight and portable.
Every sensor node is equipped with a
transducer, microcomputer, transceiver and
power source.

The transducer generates electrical signals based on
sensed physical effects and phenomena.
The microcomputer processes and stores the sensor
output.
The transceiver receives commands from a central
computer and transmits data to that computer.
The power for each sensor node is derived from the
electric utility or from a battery.

Existing System
8/6/2019 Storage Node Placement in Sensor Networks
http://slidepdf.com/reader/full/storage-node-placement-in-sensor-networks 6/37
Sensor network is given with one special sensor
identified as the sink and many normal
sensors, each of which generates data from its
environment.
Users specify the data they need by submitting
queries to the sink.
8/6/2019 Storage Node Placement in Sensor Networks
http://slidepdf.com/reader/full/storage-node-placement-in-sensor-networks 7/37
This existing system requires each sensor
to send its readings back to the sink
immediately every time it generates new data.
Generally, transferring all raw data could be
very costly and is not always necessary.

Drawbacks of Existing system
The data communication from the sensors to
the sink may take long routes consuming much
energy.
The sensors around the sink are generally
highly used and exhausted easily.

Project ObjectivePlacing the Storage nodes in sensor works
to minimize the total energy cost by
gathering data to the storage nodes and
replying queries in sensor networks.

Forwarding Nodes(Sensors)
Forwarding nodes are regular sensors and
they always forward the data received from
other nodes or generated by themselves
through a path toward the sink.

Storage Nodes
storage nodes are allowed to hold data. The
sink diffuses queries to the storage nodes by
broadcasting to the sensor network and these
storage sensors reply to the queries by sending
the processed data back.

Implementation
We first deploy regular sensors and construct
a communication tree.
We select some of the regular sensors to be
storage nodes. We can attach large flash
memory to these selected sensors or replace
them by more powerful storage nodes.

Conclusion
This system considers the storage node
placement problem in a sensor network.
Introducing storage nodes into the sensor
network to minimize the communication
burden of sending all the raw data to sink.
We place the storage nodes to save energy for
data collection and data query.
