  • 1. DESIGN & IMPLEMENTATION OF SMALL SCALE WIRELESS SENSOR NETWORK
  • 2. PRESENTATION FLOW WIRELESS SENSOR NETWORK BRIEF THEORY DEVELOPMENT PLAN HARDWARE IMPLEMENTATION PROGRAMMING AND SOFTWARE PROBLEMS TESTING AND RESULTS FUTURE WORK QUESTION AND ANSWERS
  • 3.
    • Large number of small nodes densely deployed in a region.
    • Collaborate to accomplish a common task, the data is forwarded towards a remote base station.
    • Sensor Nodes: sensing, data processing, communication.
    • Base Station: PC with node compatible wireless interface. Monitor and control all system activities.
    • Applications:
      • Intruder tracking,
      • surveillance,
      • Habitat Monitoring,
      • Monitoring Disaster areas etc.
    1. WIRELESS SENSOR NETWORK (WSN) BRIEF THEORY 1.1 INTRODUCTION WSN concept representation.
  • 4. 1.2 WSN FEATURES WSN Theory continued...
    • Self Configuration: Network formation without human intervention, both communication and positioning.
    • Special Protocols: Handling large number of nodes, broadcast medium, multihop routing.
    • Energy Efficiency: Irreplaceable node and limited battery.
    • Data Aggregation and Fusion: redundant data from multiple nodes can be aggregated.
  • 5. 2. DEVELOPMENT PLAN
    • Demonstration of WSN for Intruder Tracking Application .
    • Development of three sensor nodes having:
      • ultrasonic intruder detector,
      • Micro-controller
      • Wireless transceiver
    • Base station establishment using Wireless interfaced PC.
    • Software development for intruder trajectory mapping using node map.
