  1. 1. iMouse Integrated Mobile surveillance & Wireless Sensor System
  2. 2. Introduction <ul><li>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 . </li></ul><ul><li>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. </li></ul>
  3. 3. Static Sensors <ul><li>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. </li></ul><ul><li>An event occurs when the sensor input is higher or lower than </li></ul><ul><li>a predefined threshold. </li></ul><ul><li>Sensors can combine inputs to define a new event. </li></ul><ul><li>For example, a sensor can interpret a combination of light and temperature readings as a potential fire emergency. </li></ul><ul><li>To detect an explosion, a sensor can use a combination of temperature and sound readings. </li></ul>
  4. 4. Mobile Sensors <ul><li>Mobile sensors can move to event locations, exchange messages with other sensors, take snapshots of event </li></ul><ul><li>scenes and transmit images to the server. </li></ul><ul><li>Each mobile sensor can connect to the following equipment </li></ul><ul><li>a Lego car to support mobility </li></ul><ul><li>a mote, to communicate with the static sensors </li></ul><ul><li>a webcam, to take snapshots </li></ul><ul><li>To support high-speed, long-distance communications, such as transmitting images. </li></ul>
  5. 5. iMouse architecture
  6. 6. How static sensor can run <ul><li>Three types of messages activate a static sensor </li></ul><ul><li>Tree-maintenance message </li></ul><ul><li>Sensory input </li></ul><ul><li>Event message </li></ul>
  7. 7. Grid like sensing field <ul><li>Current prototype uses the light </li></ul><ul><li>sensors on the Lego car to navigate </li></ul><ul><li>mobile sensors. </li></ul><ul><li>We stick different colors of tape on </li></ul><ul><li>the ground, which lets us easily navigate the Lego car on a board. </li></ul><ul><li>In this prototyping, we implemented an experimental 6 by 6 grid-like sensing Field. </li></ul><ul><li>Black tape represents roads and golden </li></ul><ul><li>tape represents intersections. </li></ul><ul><li>We constructed the system by placing two mobile sensors and 17 static sensors on the sensing field. </li></ul><ul><li>For static sensors, a light reading below 800watts simulates an event. </li></ul><ul><li>So we cover a static sensor with a box tomodel a potential emergency. </li></ul>
  8. 8. Benefits of iMouse <ul><li>It provides online real time monitoring. </li></ul><ul><li>It’s event-driven. </li></ul><ul><li>The more expensive mobile sensors are dispatched to the event locations. </li></ul><ul><li>They don’t need to cover the whole sensing field, so only a small number of them are required. </li></ul><ul><li>It’s both modular and scalable. </li></ul><ul><li>Recent advances in wireless communications and MEMS technologies have made WSN possible. </li></ul>
  9. 9. Existing sysytem <ul><li>Traditional visual surveillance systems continuously videotape scenes to capture transient or suspicious objects. </li></ul><ul><li>Researchers in robotics have also discussed the surveillance issue. Robots or cameras installed on walls identify obstacles or humans in the environment </li></ul><ul><li>Some researchers use static WSNs for object tracking. These systems assume that objects can emit signals that sensors can track. </li></ul><ul><li>Researchers have also proposed mobilizers to move sensors to enhance coverage of the sensing field and to strengthen the network connectivity. </li></ul>
  10. 10. Proposed system <ul><li>The proposed iMouse system combines two areas, WSN and surveillance technology, to support intelligent mobile surveillance services. </li></ul><ul><li>On one hand, the mobile sensors can help improve the weakness of traditional WSN. </li></ul><ul><li>On the other hand, the WSN provides context awareness and intelligence to the surveillance system. </li></ul><ul><li>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. </li></ul>
  11. 11. Implementation <ul><li>iMouse is implemented in Java and Java Script . </li></ul><ul><li>We use java script to provide authentication and redirection. </li></ul><ul><li>iMouse is developed with the following java script pages. </li></ul><ul><li>1. Login Page (Authetication page – index.html)‏ </li></ul><ul><li>2.Redirecting/Home Page (connecting to iMouse – author.html )‏ </li></ul><ul><li>The core of iMouse is simulated using Java. The iMouse simulation contains the following modules . </li></ul><ul><li>1. User Interface Design(‏ </li></ul><ul><li>2. Simulation of Static sensors(‏ </li></ul><ul><li>3. Design of Wireless Sensor Networks(WSN – </li></ul>
  12. 12. User interface design <ul><li>The iMouse contains the following User Interface Design controls </li></ul><ul><li>1.Configure area </li></ul><ul><li>2.System command area </li></ul><ul><li>3.Sensor status area </li></ul><ul><li>4.Action control area </li></ul><ul><li>5.Log area </li></ul><ul><li>6.Monitor area </li></ul>
  13. 13. Class diagram <ul><li>Class diagram may be used as an alternative more graphical notation over Class Responsibility Collaborator (CRC) cards in order to record responsibilities and collaborators </li></ul>
  14. 14. UML Diagram <ul><li>iMouse Server WSN client </li></ul><ul><li>It illustrates the names of used cases and actors and relationships between them. </li></ul>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. 15. Sequence diagram <ul><li>Sequence diagram illustrate interaction in a kind of format in which each new object is added to the right </li></ul>
  16. 16. Collaboration daigram <ul><li>Collaboration diagram illustrate object interaction in a graph or network format in which objects can be placed anywhere on the diagram </li></ul>
  17. 17. Activity diagram <ul><li>Activity diagram offers rich notation to show a sequence of activities it may be applied to purpose </li></ul>
  18. 18. Component diagram <ul><li>Component diagram represents a modular, deployable and replaceable part of a system that encapsulation implementation and exposes a set of interfaces </li></ul>
