DESIGN AND IMPLEMENTATION OF A WIRELESS SENSOR NETWORK
ABSTRACT
A wireless sensor network is presented for
monitoring the energy use of electric appliances in a home environments and aquatic
environments such as lakes, ponds, drinking water reservoirs, or rivers. The
aquatic sensor network consists of an array of submerged nodes distributed
throughout the area of interest. As dependent upon the desired application,
each node of the network can be equipped with different types of sensors,
enabling measurement of physical, chemical, or biological parameters of
interest. Each node contains an acoustic transducer for underwater node-to-node
communication, with node communication protocols and sensor data processing
overseen by a programmable microcontroller. Network information is collected by
an uplink node floating on the surface of the water, which is then transmitted
via radio waves to a host node, located on shore, which uploads network data to
a computer for display and evaluation.
This paper describes the design,
implementation, and testing of a wireless sensor network for monitoring the
energy use of electric appliances in a home environment. The network includes
energy measurement nodes and a central server, where the nodes read the energy
use of connected appliance, and wirelessly report their readings to the central
server for processing. The server displays the readings from these nodes via a
user visual interface in real time. Through this system, users can easily understand
their electricity usage patterns and adapt their behaviour to reduce their
energy consumption and costs. Moreover, users are able to remotely power on/off
individual devices to actively control the power use of certain appliances. The
system allows for inexpensive monitoring of home energy use and illustrates a
practical way to control the energy consumption through user interaction.
