  1. Chapter 5: How can we cooperate within the networked enterprises?

  2. A SelfLetsystem • Composed of many interconnected nodes (SelfLets) • Completely decentralized • Each SelfLet has a goal and is able to offer services to others with different execution semantics • Do • Teach • Know who can do • It is equipped with an autonomic part that continuously monitors the internal and external known environment and changes the SelfLet normal behavior as needed (according to self-* properties) • Could represent (part of) an enterprise and cooperate with the others

  3. Self-* properties • Self-configuration • System configure itself to reach a defined goal • Self-optimization • System should configure itself to maximize a defined utility function • Self-healing • Corrective actions have to be performed if the system realizes that has reached a state preventing the reaching of its goal • Self-protection • System should detect security attacks or anomalies

  4. Features of the SelfLets approach • A conceptual model for building distributed self-organizing components • A runtime support and a programming approach • Formal modeling and analysis techniques
