      1
    • Overview
      Introduction
      Design Goals
      Design Methodology
      Primary Sub Systems
      Block Diagrams
      Applications
      Conclusion
      2
    • 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
      9
    • Web Program
      Data Retrieval Form:
      10
    • Web Program
      Generated Graphs:
      11
    • System Block Diagram
      12
    • Block Diagram – Client
      13
    • Block Diagram – Server
      14
    • Block Diagram – Server
      15
    • Block Diagram– Sensor Network
      16
    • Block Diagram – Mote
      17
    • 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
