Joint Task 6

Project Mission: Definitions OSGi: Developed by OSGi Alliance (BMW, IBM, Ericson, Siemens,

Vodafone, Sun, etc.) OSGi is a dynamic, modular, service-oriented framework over JAVA VM. Components are located in bundles.

R-OSGi : Open-source extension to OSGi, ensures high-level connection among distributed OSGi frameworks over TCP/IP.

Phsysical Device: a hardware, or set of hardwares: sensors, sensor networks, mobile phones, PDAs, UPnP camera, intelligent medical devices, actuators, home automation devices, etc.

Device components: software components, that handle physical devices, offers high-level services. These components are JAVA-based (minimum: J2ME/CDC) and meet the requirements of org.osgi.service.device specification

Driver components : software components, that serve device components. Drivers are assigned to specific technologies: Serial, UDP, USB, UPnP, etc. They also acts on org.osgi.service.device.

Share services among virtual gateways Communication:

• Remote Service Access: Remote method calls supporting complex data object transport (despite UPnP)

• Eventing: OSGi events are transported between connected peers

Automated Service Discovery in subnet Direct connection to known peers via HTTP Supports Bluetooth

Joint Task 6

Tutorial: Device Access in a nutshell Specified by OSGi Alliance, introduced in R3 release Device Access Specification – OSGi based mechanism to handle physical

devices (configuration, life-cycle management,etc.) Using the dynamism of OSGi, enables plug@play, almost zero-conf scenarios.
