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 bundles

• There 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

Environnement du projet

• Durée 12 semaines
• Tuteur Stéphane Frenot
• Lieu laboratoire CITI, INSA de Lyon
• Deuxième année du projet

18
Cahier des charges

• Reprendre le projet en létat et l avancer au
  maximum
• Il faut rendre le programme le plus autonome et
  fiable possible
• Fonctionnement par étapes directives,
  réalisation, validation et à nouveau directives...

19
Nos réalisations techniques

• Prise en main du projet
• Étude de lexistant
• Réalisation de schémas de fonctionnement
• Plan de tests / débugage
• Réalisation des procédures de stop

20
Nos réalisations techniques

• Gestion du matériel PCMCIA dans Oscar
• Étude du package pcmcia_cs (Card Manager)
• Analyse des fonctions clés
• Implémentation de ces fonctions
• Intégration avec lexistant
• Tests et validation

21
Délivrables

• un package contenant les sources et la
  documentation
• Création dun site web en anglais concernant le
  projet
• guide dinstallation, de compilation,
  documentation technique, téléchargement,
  bibliographie
• Rapports de notre PFE

22
Retour dexpérience

• administration des systèmes UNIX
• compilation du noyau, fichiers virtuels, gestion
  des devices, signaux
• programmation
• Oscar / bundles, JNI, Programmation système UNIX
  en C des devices et des drivers
• humain
• gestion dun projet de développement site web,
  cahier de bord...

Rapport  Services Usages

• 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?
