Goals for AmI

• Self configuring devices

• “Calm computing” [weiser1995]

• Context Awareness

6


Architecture

• Client-/Server

• Peer-to-peer

7


Client/Server Architecture

• Benefits:

• Easy to configure

• Simple routing

• Drawbacks

• Single point of failure

• Additional hardware

8


Peer-to-Peer

• Benefits

• robustness

• performance

• Drawbacks

• service discovery

9


Meta-Data

10

• What

• When

• Where (Source/Destination)

• How long

• ...


• Files

• Information

Data


Communication & Exchange

12


Requirements

• Service Discovery

• Service Propagation

• Exchange of meta data

• Exchange of files and information

13


• First Level: Access to the Network

• Second Level: Offering and Consuming Services

14

Two Levels of Service Discovery


• Part of iROS

• Blackboard

• Services announced on central instance

• events are interpreted by devices

15

EventHeap


EventHeap - consideration

• Positive

• events interpreted by clients

• flexible, robust

• Negative

• events interpreted by clients

• server as bottleneck

16


Oxygen

17


Oxygen

• Vision (?) of Human Centered Computing

• Stationary devices, hand-held devices, infrastructure, networks, software architecture

• Automation, collaboration

18


Oxygen - consideration

• Benefits

• Comlete concept for pervasive human centered computing

• Drawbacks

• Software not available (?)

19


Dynamic Adaptive Multimodal IT-Ensembles

• Intelligent multimodal interaction

• distributed networked devices

• dynamical changeable ensembles

20


DynAMITE - Entertainment Demo

21

http://www.igd.fhg.de/igd-a1/dynamite-project/english/index.html




DynAMITE

• Decentralized middleware

• Self-organizing device ensembles

• Peer-to-peer

22


DynAMITE - consideration

• Benefits

• Self-configuring environment

• Conflict resolution

• Drawbacks

• Clients have to be rather “smart”

• Communication via broadcasts (?)

23


Jadex / Agent based Middleware

• Smart Agents

• Jadex executes Agents

• Communication via Messages/Events

24


Agent based Middleware - consideration

• Benefits

• “pluggable” intelligence

• standardized communication

• peer to peer possible

• Drawbacks

• heavyweight clients

25


Other already discussed approaches

• CAMUS [urich2007]

• PIE [pierce2007]

• Distributed file systems [gaerner2007]
