Engineering and implementing software architectural patterns based on feedback loops

A highly decentralized system of autonomous service components consists of multiple and interacting feedback loops which can be organized into a variety of architectural patterns. The highly complex nature of these loops make engineering and implementation of these patterns a very challenging task. In this paper, we present SimSOTA-an integrated Eclipse plug-in to architect, engineer and implement self-adaptive systems based on our feedback loop-based approach. SimSOTA adopts model-driven development to model and simulate complex self-adaptive architectural patterns, and to automate the generation of Java-based implementation code. The approach is validated using a case study in cooperative electric vehicles.
