ApplicationsApplications

PDAs, smart phones, WiFi, 3G, RFID : where/what are pervasive applications?

Smart fridge, smart cars, robotic hovers/mowers : where are the mainstream offers, where is the interoperability?

Weather /mood connected lamp, (AR) PacMan in the streets of Taiwan:

where is the public?

Etc.

Are we there yet?

Why?

The 2 Faces of EmulationThe 2 Faces of Emulation

Existing Bricks Architectures

In computer science

and other scientific fields

To emulate:

• (Computer Science) To imitate the function of another system (not necessary at the same speed)

• Effort or ambition to equal or surpass another

• To strive to equal/match or excel, especially through imitation

Real Test-beds vs. EmulationReal Test-beds vs. EmulationReal Test-bed Emulation/simulation

Expensive

Difficult to set up/maintain

Limited scale

Quick obsolescence

Fixed location

Replay difficult

Class of applications - oriented

Safety and privacy issues for specific applications

Reduced cost

Quick set-up, prototyping, development

Scalability

Consistent/coherent replay

Safe

Reality check! It’s not reality

Reality is more complex

Modeling is difficult

Real-time is even more difficult

Validity?

What features would you like to see?

Developing applications shouldn’t/doesn’t imply lots of money and hardware and rebuilding almost everything from scratch
