By way of the development of network and
communication technology, the inconvenience of wiring is
solved with Wireless Sensor Network (WSN). It has wide
perspective and practicability in the area of remote
sensing, industrial automation control, and domestic
appliance. It is used for data collection, transmission, and
processing. It has many advantages compared to
traditional wired network, like convenient organizing
network, small influence to environment, low power
dissipation, low cost, etc. They have a number of
disadvantages like complexity, large power dissipation,
short distance, networking in small scale. A wireless sensor
network is a collection of large number of sensor nodes and
at least one base station. The sensor node is an autonomous
small device that consists of mainly four units that are
sensing, processing, communication and power supply.
These sensors are used to collect the information from the
environment and pass it on to base station. A base station
provides a connection to the wired world where the
collected data is processed, analyzed and presented to
useful applications. Thus by embedding processing and
communication within the physical world, Wireless Sensor
Network (WSN) can be used as a tool to bridge real and
virtual environment.

Wireless Sensor Network(WSN)
Network
WSN is a promising technology and used in a range of
application that requires minimum human intervention.
Researchers have designed a number of network
configurations like heterogeneous and single-hop which
uses WSN. The flexibility, fault tolerance, high sensing
fidelity, low-cost and rapid deployment characteristics of
sensor networks create new and exciting application areas for remote sensing. A wide range of application
areas will make sensor networks an integral part.
However, realization of sensor networks needs to satisfy
the constraints.
