Transcript

  • 1. Kalimucho - OW2 annual conference 1 KALIMUCHO1 Marc Dalmau, Philippe Roose IUT of Bayonne LIUPPA / University of Pau - France • Paris • Bayonne 1 Kalitatea means « Quality » in Basque language, Mucho means « a lot » en Spanish language
  • 2. Kalimucho - OW2 annual conference 2 Objectives of Kalimucho • Kalimucho is a platform that allows development of applications distributed on several kind of devices: • PC • Smartphones • Tablets • Sensors • … • Application are made of components • The components of these applications exchange flows of data • Components can be added/removed/migrated while the application is running: • On users requests • Because of context changes (mobility …) • According to available resources (network, energy, CPU, memory …)
  • 3. Kalimucho - OW2 annual conference 3 Why a platform ? • Classical solutions: • Embedded = ad hoc application (=> can be heavy) • Self or no adaptation • Our solution: • Components of the application are downloaded when needed and removed when not yet used (=> light and evolutive) • Components can be created / stopped / moved at any time without stopping the running application • Communications between components are transparent to the designer: they send / receive data and the platform decides from/to where
  • 4. Kalimucho - OW2 annual conference 4 Applications • Made of services • (an application = a set of services) • Services are assemblies of components • (a service = an assembly of components with connectors) • Components are simple • (a component = a function) • Dynamic deployment and reconfiguration of applications • Add a new user / Remove a user • Add/Remove a service • Modify the constitution of a service • Dynamic adaptation of the application • To the context • To the users • To the usage
  • 5. Kalimucho - OW2 annual conference 5 Application model • Distributed components linked by connectors • A component has 0 to N inputs • A component has 0 or 1 output that can be duplicated
  • 6. Kalimucho - OW2 annual conference 6 Example of application • An organism taking care of environment sends an agent (with a smartphone) to the scene of an environmental accident 1. At his arrival he films the scene he and sends the video (in streaming mode) to the organism's center. 2. The center wants this video to be sent to an expert who is not actually in the center but has a smartphone. 3. The expert decides that it is necessary to get pictures in order to constitute a file. These pictures will be sent simultaneously to the him and to the center. 4. In order to complete the information in the file the center wants these pictures to be tagged by their GPS position. 5. Etc .
  • 7. Kalimucho - OW2 annual conference 7 Scene Center Act #1: Arriving on the scene • Video captured by the agent’s smartphone is sent to the center Kalimucho Kalimucho Video capture Video display Deployment : Commands executed by the platforms Agent : CreateComponent video application.video.VideoAcquisition [null] [vid] Agent : CreateConnector vid internal Center Center : CreateComponent videodisplay application.videodisplay.VideoDisplay [vid] [null]
  • 8. Kalimucho - OW2 annual conference 8 Act #2: The expert • Video is now received by the expert Kalimucho Kalimucho Video capture Kalimucho Center Scene Expert Commands executed by the platforms Center : SendComponent videodisplay Expert Video display Kalimucho Scene Center Scene
  • 9. Kalimucho - OW2 annual conference 9 Act #3: Taking pictures • Video is replaced by pictures Kalimucho Kalimucho Video capture Video display Kalimucho Centre Scene Expert Commands executed by the platforms Agent : RemoveComponent video Expert : RemoveComponent videodisplay Expert : RemoveConnector vid
  • 10. Kalimucho - OW2 annual conference 10 Kalimucho Centre Pictures display Kalimucho Expert Act #3: Taking pictures • Video is replaced by pictures Kalimucho Picture capture Scene Commands executed by the platforms Agent : RemoveComponent video Expert : RemoveComponent videodisplay Expert : RemoveConnector vid Agent : CreateComponent pictures application.camera.PictureAcquisition [null] [tocenter] Center : CreateConnector tocenter Agent internal Center : CreateComponent picturesdisplay application.camera.PictureDisplay [tocenter not_used] [null] Expert : CreateComponent picturesdisplay application.images.PictureDisplay [toexpert not_used] [null] Agent : CreateConnector toexpert internal Expert Agent : DuplicateOutputComponent photo toexpert Pictures display
  • 11. Kalimucho - OW2 annual conference 11 Act #4: Adding GPS tags • Pictures sent to center are tagged by their GPS position Kalimucho Kalimucho Picture capture Picture display Kalimucho Centre Scene Expert Picture display GPS capture Commands executed by the platforms Agent : CreateComponent position application.GPS.GPSAcquisition [null] [tag] Agent : CreateConnector tag internal Center Center: ReconnectInputComponent picturesdisplay 1 tag
  • 12. Kalimucho - OW2 annual conference 12 Unpredictable context changes • In this example all the decisions were taken because of utility • but .. • If, when sending the video to the expert, the platform detects that the quality is bad (network throughput too low). It can decide by itself to send pictures rather than video: the video capture and video display components will be replaced by a picture capture and a picture display component. • Later, if the expert moves and get a better reception, the platform can choose to come back to the video mode as initially. • ….

  • 50. Kalimucho - OW2 annual conference 50 Developing applications • Only BCs and classes of exchanged data are to be developed • BC inherits from an abstract class (BCModel) • Life cycle is controlled by: • init executed only the first time (not after a migration) • destroy executed when stopped (either before a migration) • run_BC BC activity • Inputs can be read by • Direct blocking method • Listeners • Output is written by • Direct method
  • 51. Kalimucho - OW2 annual conference 51 Developing applications • Kalimucho offers services to the BCs for: • Resources access (resources loaded with the code) • User interface definition and management (on Android) • Hardware access (GPS, SMS, GoogleMaps, sensors, camera) • Sending commands to a local or a distant platform and receiving replies • BCs exchange data of user defined classes • Data classes inherits from a Kalimucho’s class (Sample) • Data classes code availability is managed by the platform • Data is time stamped when created and the date is adjusted to local time when received (DNS)
  • 52. Kalimucho - OW2 annual conference 52 Example: The BC for GPS acquisition public void destroy() throws StopBCException, InterruptedException { localGPS.stopGPS(); // stop the GPS for this BC } public float levelStateQoS() { return 0.9f; // actual QoS of this BC } } public class GPSAcquisition extends BCModel { private static final long serialVersionUID = 64240010100000001L; private transient GPSAccess localGPS; // not sent by migration private double latitude, longitude, altitude; // sent by migration public void init() throws StopBCException, InterruptedException {} public void run_BC() throws StopBCException, InterruptedException { localGPS = (GPSAccess)ServicesRegister.waitForService("GPS_ACCESS"); localGPS.startGPS(); // start the GPS for this BC while (isRunning()) { Location loc = localGPS.getGPSLocation(); latitude = loc.getLatitude(); longitude = loc.getLongitude(); altitude = loc.getAltitude(); writeSample(new GPSCoordinates(latitude, longitude, altitude)); Thread.sleep(10000); // send location every 10s } }
  • 53. Kalimucho - OW2 annual conference 53 Exchanged data: the class GPSCoordinates public class GPSCoordinates extends Sample { private static final long serialVersionUID = 64240010100000001L; private double latitude, longitude, altitude; public GPSCoordinates() { latitude = 0; longitude = 0; altitude = 0; } public GPSCoordinates(double lat, double longt, double alt) { latitude = lat; longitude = longt; altitude = alt; } public double getLatitude() { return latitude; } public double getLongitude() { return longitude; } public double getAltitude() { return altitude; } }
  • 54.
