  • Introduction
    • Wireless Sensor Networks
    • One of MIT's 10 emerging technologies
    • Low-power systems
    • New applications: sensing, controls, automation
    • WISENET: Wireless Sensor Network
    • Office environment monitoring
    • Temperature, humidity, light
    • Quantitively evaluate heating & A/C systems
    • Funding & support provided by Honeywell, Int'l.
    3
  • Design Goals
    Use of Commercial-Off-The-Shelf (COTS) software & standard interfaces where applicable
    Apache web-server (HTTP)
    MySQL database
    PHP web programming language
    Simple, web-based user interface
    Battery-powered, wireless sensor nodes: 'motes'
    Low-power consumption = Long battery life
    Motes create self-organizing ('ad-hoc') networks for robust communications
    4
  • Design Methodology
    Top-Down Design Process
    Define major subsystems
    Define subsystem interfaces
    Primary Subsystems:
    Client
    Standard Web browser via Internet
    Server
    Wireless mote network
    5
  • System Block Diagram
    6
  • Subsystem – Server
    7
  • WiseDB
    Written in C++
    Utilizes open-source APIs
    Application Programming Interfaces (API)
    MySQL++ database API
    Serial API
    Relays information from mote network to database
    Sends commands to mote network
    8
  • Web Program
    Written in PHP4
    Utilizes Charting Software: ChartDirector v3.0
    Generates 3 Graphs (default)
    Passes Parameters via HTTP GET
    Use bookmarks for specific queries
    Retrieves Data for Specific Mote or All Motes

  • TinyOS
    • Real-time operating system for microcontrollers
    • Open-source project at UC Berkeley
    • Key Features:
    • Developed for sensing applications
    • Emphasis on low-power: Idle & sleep modes
    • Highly modular architecture
    • Efficient utilization of resources
    • Currently developed for Atmega microcontrollers
    18
  • Applications
    Lab / Office Monitoring
    Habitat Monitoring
    Security Applications
    Extreme Weather Surveillance
    Potential Biomedical Applications
    Military Reconnaissance
    19
  • Conclusion
    WISNET is smaller and faster
    Emerging technology that will change the world
    Many real-world applications
    Low-power
    Open-source software
    Modular mote application design (TinyOS)
    Flexible server implementation
    Simple user interface via the web
