Service discovery and composition in ubiquitous computing

An autonomous decentralized system based on mobile agents and inspired by the immune system as an approach to adaptive service discovery and composition. The immune system has a set of organizing principles such as scalability, adaptability and availability that are useful for developing a networking model in highly dynamic and unstable setting. Each user request is considered as an attack launched against the global network. The agent-based system reacts like an immune system against pathogens that have entered the body. It detects the infection and delivers an appropriate response to eliminate it. The C-agents can rearrange at run-time by changing affinity values based on user satisfaction and dynamically change of resources. The online service composition with adaptation shows its effectiveness compared to service composition without adaptation.
