Agenda

• Sensor Query Technology
• Graphical Technology Tools
• Can we combine these two?
• Create a LabVIEW sensor toolkit ?
• Softwire marketplace ?

Sensor Query Technology - Sensor ML

• http//stromboli.nsstc.uah.edu/SensorML
• Allows visual interaction with historic sensor
  data, mostly geographic data.

SensorML
5
Sensor Query Technology - Cornell Cougar

• Allows graphical query by interacting with map -
  not clear about higher level queries.

Sensor Query Technology

• ISI Diffusion - http//www.isi.edu/scadds/projects
  /diffusion.html - data disemmination paradigm
• ISI-East

Graphical Programming - Intro

• Heirarchical
• Quick to learn - especially for novices
• Optimized for code reuse and sharing
• Good for novice users to query sensor networks?

9
Graphical Technology - LabVIEW

• Graphical Programming Environment, also
  integrates C, MatLAB
• Dataflow paradigm
• Function Palette and Control Palette

10
Graphical Technology - LabVIEW

• Now supports web and database services
• (sql, daq xml, DataSocket)
• Could support a sensor Toolkit
• Demo

11
Sensor Toolkit Ideas

• Functions to be included
• Where, When, What
• Heirarchy of functions

12
Graphical Technology - Softwire

• Eliminate thousands of lines of code that you
  currently must develop and maintain.
• Combine controls with text code, on top of .net
  C, and VB

13
Graphical Technology -Softwire

• Seamless integration with Microsoft's Visual
  Studio IDE
• Becomes part of Visual Studio .NET
• Projects can be constructed purely from SoftWIRE
  controls and wires, or may include code you write
  and .NET components

Graphical Technology - Softwire

• Components can be offered for sale in the built
  in online marketplace.
