Introduction to AWAP

Main objective: implementing a platform on which services are managed dynamically through a network

Application developed: implementation of an intelligent Wireless antenna

Environment of services: OSGi, and one of its free implementation Oscar

4

OSGi

Started December 1998 as an initiative from ERICSSON, SUN and IBM Market trend : the ubiquity of broadband connectivity and

Internet access in homes, offices, vehicles and mobile/portable devices increase from $2.4 billion in 2000 to $14.8 billion in 2005 for

broadband revenue in the U.S

home networking equipment and residential gateways will grow from $800 million in 2000 to $5.7 billion in 2004

Goal : define a software framework for all kind of service deployment on electronic devices

OSGi Overview

OSGi platform overview

• Enables the deployment of Java-oriented services : portable byte code, security...

• Component model

• Life Cycle : Install, Start, Stop, Update, Uninstall

• Remote management

• Basic utility services: Logging, HTTP, Device access

7

Implementation of AWAP

First task of AWAP : implement the devices management, described in OSGI specification

First application developed : management of the PCMCIA bus with a Wireless card

8

Devices Management

3 bundles families: core: bundles representing the device service

specification tools: some tools and testing bundles sample: bundles for devices and driver

samples. The example chosen for AWAP is the management of the PCMCIA bus.

9

Core bundles

There are 2 core bundles: devicemanager.jar: provides the main

implementation that listens to a registering device and tries to find a corresponding driver

driverlocator.jar: provides a service that search drivers bundles for a specific device

10

Tools bundles

There are 4 tools bundles: modulemanager : enables to install or remove

Linux modules. logger: is a bundle that displays log results httpresources: is a bundle that registers the url

mapping of the http server wlandrivertest : is a test bundle that triggers a

test method on the wlandriver bundle.

11

Sample bundlesThere are 3 sample bundles:

pcmciadevice : represents the PCMCIA bus in Oscar.

pcmciadriver : is the driver corresponding to the pcmciadevice. It is in charge of listening for events from the slot (card insertion/removal)

wlandriver : is the driver corresponding to the wlandevice.

As the wlandevice is a refined device, depending on the existence of the pcmciadriver, it is included in this bundle

TODO

Mount/unmount the wlan interface when the WlanDevice is registering/unregistering

Configuration of the interface using parameters defined by the user

Make the program completely independent from the operating system

Réflexion sur les usages de notre PFE : l ’immixtion des réseaux informatiques dans nos vies Que sont les "objets communicants" ? Que nous apportent ils? (intelligence ambiante) Quels sont les dangers liés à leur utilisation?
