Presentation Transcript

  1. Workplace Applications of Sensor Networks Intel R&D and USC/ISI 2004

  2. Motivation • To improve workplace productivity • Existing sensors • Thermometers, barometers, safety monitors • Isolated, for a single application + • Emerging sensor network technology • In ubiquitous, ad-hoc deployment • Dynamic user interaction

  3. Outline • Hardware • App-1:Conference Room Scheduling • App-2:Follow-Me Guidance • Challenges

  4. Hardware • Sensor nodes:Mica2, Mica-Z, Telos • Display nodes:LED,LCD • Handheld nodes:PDA • Gateway nodes:Stargate

  5. Conference Room Scheduling • Objective: To assist workers to find conference rooms in a dynamic way. • Bi-directional information transmission: • Sensing: Gather room status information • Actuation: Forward reservation information

  6. Follow-Me Guidance • Objective: To guide visitors. • Key innovation: Use “deployment order approach” to configure the network in a logical topology. Sensor Deployment Logical Topology

  7. More on Follow-Me Deployment order approach 1) Linear Paths: in a sequential way 2) Intersection: manually handling

  8. Challenges • Power: Power outlet Vs Battery • Communication Protocols: • Topology-aware protocol • Synchronization protocol • More User Interaction • To guide multiple visitors at the same time in Follow-Me
