Towards an Architecture Model for Dynamic Software Product Lines Engineering
Edilton Lima dos Santos, Ivan Machado · 2018
Dynamic Software Product Lines (DSPL) engineering makes it possible to deliver software products capable of adapting to fluctuations in user needs and evolving resource constraints at runtime. Based on an architecture-centric approach, a DSPL is capable to analyze changes in context, thus responding by performing system adaptations. In this work, we propose an architecture model for DSPL engineering based on the MAPE-K model concept, a feasible strategy to gather and analyze contextual information thus enabling product reconfiguration at runtime. We evaluated the proposed architecture model in a Smart Home System, using OSGi and MQTT. The results are promising, as the DSPL demonstrated its capability to adapt and reconfigure itself according to the new sensors connected to the system.
