Average User Interface

Conclusion (1/2)

• A gateway for services presence and discovery

▫ Translate an information of service discovery

into a presence information

• The architecture

▫ Modular

▫ Extensible

• Assessment

▫ SIP/SIMPLE protocols

▫ Bluetooth and RFID technologies

24

Conclusion (2/2)

• Graphical User Interfaces

▫ An Interface for administrators

▫ An Interface for average users

25

Prospects

• Connect several gateways to a main gateway▫ The main gateway provide the presence

information

• Add New Technologies ▫ Plug in new modules in the gateway

• Once a service is detected :▫ Use of the service

Take into account the service Invocation
