Workplace Applications of Sensor Networks

Intel R&D and USC/ISI 2004

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

Outline Hardware

App-1:Conference Room Scheduling

App-2:Follow-Me Guidance

Challenges

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

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

Follow-Me Guidance Objective:

To guide visitors.

Key innovation: Use “deployment order approach” to configure the network in a logical topology.

Logical Topology

Sensor Deployment

More on Follow-MeDeployment order approach

1) Linear Paths: in a sequential way

2) Intersection: manually handling

Challenges Power: Power outlet Vs Battery

Communication Protocols: Topology-aware protocol Synchronization protocol

More User Interaction To guide multiple visitors at the same time
