  • 1. iMouse Integrated Mobile surveillance & Wireless Sensor System
  • 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.
  • 5. iMouse architecture
  • 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.
  • 11. Implementation
    • iMouse is implemented in Java and Java Script .
    • We use java script to provide authentication and redirection.
    • iMouse is developed with the following java script pages.
    • 1. Login Page (Authetication page – index.html)‏
    • 2.Redirecting/Home Page (connecting to iMouse – author.html )‏
    • The core of iMouse is simulated using Java. The iMouse simulation contains the following modules .
    • 1. User Interface Design(‏
    • 2. Simulation of Static sensors(‏
    • 3. Design of Wireless Sensor Networks(WSN –
  • 12. User interface design
    • The iMouse contains the following User Interface Design controls
    • 1.Configure area
    • 2.System command area
    • 3.Sensor status area
    • 4.Action control area
    • 5.Log area
    • 6.Monitor area
  • 13. Class diagram
    • Class diagram may be used as an alternative more graphical notation over Class Responsibility Collaborator (CRC) cards in order to record responsibilities and collaborators
  • 14. UML Diagram
    • iMouse Server WSN client
    • It illustrates the names of used cases and actors and relationships between them.
    ADMIN LOGIN Activate Mobile Sensor Activate Static Sensor Deactivate Static/Mobile Sensor iMouse Server, to initiate iMouse applications Client which asks events and status data from server
  • 15. Sequence diagram
    • Sequence diagram illustrate interaction in a kind of format in which each new object is added to the right
  • 16. Collaboration daigram
    • Collaboration diagram illustrate object interaction in a graph or network format in which objects can be placed anywhere on the diagram
  • 17. Activity diagram
    • Activity diagram offers rich notation to show a sequence of activities it may be applied to purpose
  • 18. Component diagram
    • Component diagram represents a modular, deployable and replaceable part of a system that encapsulation implementation and exposes a set of interfaces
  • 19. Software & Hardware Requirements
      • Programming :JDK 1.5 and higher
    • :java script
    • :Net-Beans 6.5
    • Web server :Apache tomcat6.0
    • Deployment :Glassfish
    • Processor Name :Pentium 4 or above versions
    • Ram :512MB or above
      • Operating System :Windows XP
  • 20. Conclusion
    • With iMouse we can implement WSN which can detect any event at a desired position in sensing field without human interaction directly.
    • By this project we can implement low cost based surveillance system which is user friendly and easily recognises places in any real world system.
