  4. 4. Introducción - Main Concepts - Ad-Hoc Networks Mobile Agents & Nomadism Multi-Agent Systems & Platform Service Discovery10/04/08 Diego Casado Mansilla - Applied Computing 2008
  5. 5. Ad-hoc Networks Main features Dynamic, Sporadic & Unpredictable No configuration needed Decentralized topology Distributed MANET “Multi-hop” ➢ AODV Routing ➢ DSR10/04/08 Diego Casado Mansilla - Applied Computing 2008
  6. 6. Ad-hoc Networks Main disadvantages Power limitation Bandwith Efficiency QoS Communication (Network Layer)10/04/08 Diego Casado Mansilla - Applied Computing 2008
  7. 7. Multi-Agent Systems Mobile Agents Processes at application layer Autonomy, proactivity, sociability & mobility Multi-Agent Systems Cooperation, Coordination & Communication between Agents Decentralized & Scalability Asynchronous communication (avoid C/S) Reduce data load, BandWith. Distributed Services10/04/08 Diego Casado Mansilla - Applied Computing 2008
  8. 8. Multi-Agent Systems Service Discovery Multi-Agent Platform --> JADE(middleware) DF (Directory Facilitator) AMS (Agent Management System) Fault Tolerance Allow Decentralization and Main Node Replica Avoid Single point of failure Every Agent: know where the DF is is aware of any platfrom changes10/04/08 Diego Casado Mansilla - Applied Computing 2008
