> The remarkable advances of micro sensing micro
electromechanical systems (MEMS) and wireless communication
technologies have promoted the development of wireless sensor
networks. A WSN consists of many sensor nodes densely deployed
in a field, each able to collect environmental information .
> WSNs provide an inexpensive and convenient way to monitor
physical environments. With their environment-sensing capability,
WSNs can enrich human life in applications such as healthcare,
building monitoring, and home security.
WHAT IS IMOUSE…?
> Incorporating the environment sensing capability of
wireless sensor networks into video based surveillance systems
can provide advanced services at a lower cost than traditional
surveillance systems .
> The integrated mobile surveillance and wireless sensor
system (iMouse)use static and mobile wireless sensors to detect
and then analyze unusual events in the environment.
WHAT IS WSN…?
>A wireless sensor network (WSN) is a wireless
network consisting of spatially distributed autonomous
devices using sensors to cooperatively monitor physical
or environmental conditions, such as temperature,
sound, vibration, pressure, motion or pollutants, at
APPLICATIONS OF WSN
The applications for WSNs are many and varied. They are used in
commercial and industrial applications to monitor data that would
be difficult or expensive to monitor using wired sensors.

The three main components of the iMouse system architecture are:
>Static sensors forms a WSN to monitor and notify to server of
unusual events.The sensing board can collect three types of data:
>An event occurs when the sensor input is higher or lower than
a predefined threshold.
>Sensors can combine inputs to define a new event.
For example, a sensor can interpret a combination of light and
temperature readings as a potential fire emergency.
> To detect an explosion, a sensor can use a combination of
temperature and sound readings
BENEFITS OF IMOUSE
>It provides online real time monitoring.
>The more expensive mobile sensors are dispatched to the
>They don’t need to cover the whole sensing field, so only a
small number of them are required.
>Recent advances in wireless communications and MEMS
technologies have made WSN possible.
>Traditional visual surveillance systems continuously videotape
scenes to capture transient or suspicious objects.
>Robots or cameras installed on walls identify obstacles or humans
in the environment
>Some researchers use static WSNs for object tracking. These
systems assume that objects can emit signals that sensors can track.
>Researchers have also proposed mobilizers to move sensors to
enhance coverage of the sensing field and to strengthen the network
>The proposed iMouse system combines two areas, WSN and
surveillance technology, to support intelligent mobile surveillance
>On one hand, the mobile sensors can help improve the weakness
of traditional WSN.
>On the other hand, the WSN provides context awareness and
intelligence to the surveillance system.
>WSN’s status and control includes Config, Command, Status,
Control, Monitoring and Log areas. The Config area is to input
configuration information, such as mobile sensors’ IP addresses,
ports, sensors’ positions,etc.
>With iMouse we can implement WSN which can detect any event
at a desired position in sensing field without human interaction
> By this we can implement low cost based surveillance system
which is user friendly and easily recognises places in any real
