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
