  1. Interoperable Multi-AgentSystems in Near-FieldCommunication Networks Mathias Rieder

  2. Contents Understand the architecture of JADE.Develop an implementation strategy for an Extension without corrupting the architecture or the implemented standards Implement and test a Bluetooth Message Transport Protocol. • Motivation • MAS / Agent • Standards • JADE • Jade Bluetooth Extension Show the role and the purpose of interoperability standards Develop an understanding for Multi-Agent Systems and for Software Agents Interoperable MAS in NFC Networks

  3. Motivation • Moreno, Valls& Viejo presented an implementation of a MAS for mobile devices1) • Always-connected & IP-based (GPRS) • Implementation for MIDP/CLDC (Java MicroEdition) • They omit the idea of using short range communication technologies for building MAS 1) Antonio Moreno, AïdaValls, Alexandre Viejo, Using JADE-LEAP to implement agents in mobile devices, 2002 http://www.gsmworld.com Interoperable MAS in NFC Networks

  4. MAS • “looslycoupled network of problem solvers that interact to solve problems that are beyond the individual capabilities or knowledge of each problem solver” [Durfeeand Lesser, 1990] • distributed Agents with incomplete of information or capabilities to solve a problem • No system global control • No centralized knowledge base • Agents run asynchronously / in parallel[Sycara, 1998] Interoperable MAS in NFC Networks

  5. Agent • [Russel and Norvig, 2003] • Agent Function f … Agent FunctionP ... all possible perceptions (measurements)E … EnvironmentA … all possible Actions Interoperable MAS in NFC Networks

  6. Standards • Foundation For Intelligent Physical Agents – FIPA • FIPA Abstract Architecture • promote interoperable agent applications and to define a common agent infrastructure Interoperable MAS in NFC Networks

  7. Standards (2) • MAS Interoperability • Agent Interoperability Interoperable MAS in NFC Networks

  8. JADE • Java Agent Development • 100% pure Java Interoperable MAS in NFC Networks

  9. JADE (2) • How do Agents communicate with each other? • FIPA compliant Message Transportation • Asynchronous Messaging (Mailbox) Interoperable MAS in NFC Networks

  10. JADE (3) • How do Containers manage Message Transport? • JADE Containers implement the Composite Filter Pattern • Decorate an Object with a chain of filters for incoming and outgoing method calls. (inspired by Aspect-oriented programming) [Bergmansand Aksit, 2004] Interoperable MAS in NFC Networks

  11. JADE (4) • How do Containers manage the Message Transport? • Agents communicate with the container using the Command-Pattern. The commands travel through the filter chain (Composite Filters) Interoperable MAS in NFC Networks

  12. JADE (5) • How to tell the container to use Bluetooth? • Message Delivery Filter (“CommunicationChannel”) must be extended in order to use Bluetooth Interoperable MAS in NFC Networks

  13. JADE Bluetooth Extension Interoperable MAS in NFC Networks

  14. JADE Bluetooth Extension (2) • Connection SetupBT-InquiryService Discovery • ~ 17 sec  • Avg. Roundtriptime • ~250 ms Interoperable MAS in NFC Networks

  15. Future Work • More detailed performance measurements • Implement test-scenarious proposed by [Vitaglione et al., 2002]. • Message Routing • Inter-container routing in order to support higher distance • Fully distributed MAS • Implement the FIPA components (AMS, DF) as fully distributed databases as proposed by [Jinbae Park, 2009] in order to get rid of the Main-Container.
