The iMouse system combines wireless sensor networks and mobile surveillance to provide advanced monitoring services at a lower cost than traditional systems. Static sensors form a wireless sensor network to detect events like changes in light, sound or temperature. Mobile sensors can then move to the event locations to take photos and transmit information to the server. The iMouse architecture uses static and mobile sensors on an experimental 6x6 grid to detect simulated events and test the system's real-time monitoring, event-driven response and scalability.

2. Introduction 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.

3. Static Sensors Static sensors forms a WSN to monitor and notify to server of unusual events.The sensing board can collect three types of data: light,sound,temperature. 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.

4. Mobile Sensors Mobile sensors can move to event locations, exchange messages with other sensors, take snapshots of event scenes and transmit images to the server. Each mobile sensor can connect to the following equipment a Lego car to support mobility a mote, to communicate with the static sensors a webcam, to take snapshots To support high-speed, long-distance communications, such as transmitting images.

6. How static sensor can run Three types of messages activate a static sensor Tree-maintenance message Sensory input Event message

7. Grid like sensing field Current prototype uses the light sensors on the Lego car to navigate mobile sensors. We stick different colors of tape on the ground, which lets us easily navigate the Lego car on a board. In this prototyping, we implemented an experimental 6 by 6 grid-like sensing Field. Black tape represents roads and golden tape represents intersections. We constructed the system by placing two mobile sensors and 17 static sensors on the sensing field. For static sensors, a light reading below 800watts simulates an event. So we cover a static sensor with a box tomodel a potential emergency.

8. Benefits of iMouse It provides online real time monitoring. It’s event-driven. The more expensive mobile sensors are dispatched to the event locations. They don’t need to cover the whole sensing field, so only a small number of them are required. It’s both modular and scalable. Recent advances in wireless communications and MEMS technologies have made WSN possible.

9. Existing sysytem Traditional visual surveillance systems continuously videotape scenes to capture transient or suspicious objects. Researchers in robotics have also discussed the surveillance issue. 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 connectivity.

10. Proposed system The proposed iMouse system combines two areas, WSN and surveillance technology, to support intelligent mobile surveillance services. 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.
