Abstract:
Smart environment is a technological concept in which the physical world that
is richly and invisibly interwoven with sensors to gather and process their
sensed data. While using certain communication framework send this
information to actuators which take certain actions to control the environment.
The SMART ENVIORNMENT project is exactly based on the same idea. The
two basic things of interests in our smart environment are intrusion and
overheating detection for fire. The reason for the selection of these two
entities is that security and safety are critical in all aspects of today’s world. In
order to ensure safety easily deployable and easy to afford solutions are
required. The Smart Environment Project is just one of those solutions that
can be used as a basic tool for the detection of intrusion with homes and
offices along with the provision to detect overheating. For this purpose, Texas
Instrument’s Ez430-RF2500 devices are used which are equipped with
temperature sensors while PIR sensors for intrusion detection are also
attached to these devices for intrusion detection. Ez430-RF2500 are low
power and resource constrained which support a star topology network. The
basic aim of this project is to establish a multi-hop network with these devices
to enhance the coverage area of the network for which IETF ROLL (Routing
on Low power and Lossy networks) routing protocol has been implemented
on these devices. A desktop application (Smart Monitoring System) is also
developed to graphically represent the gathered information from different
field sensors. This application generates visual, audio and sms based alerts to
notify the end user in case of any critical event.
