AB The execution context in which pervasive systems or mobilecomputing run changes continuously. Hence, applications for these systemsshould be adapted at run-time according to the current context.In order to implement a context-aware dynamic reconfiguration service,most approaches usually require to model at design-time both the list ofall possible configurations and the plans to switch among them. In thispaper we present an alternative approach for the automatic run-time generationof application configurations and the reconfiguration plans. Thegenerated configurations are optimal regarding di erent criteria, such asfunctionality or resource consumption (e.g. battery or memory). This isachieved by: (1) modelling architectural variability at design-time usingCommon Variability Language (CVL), and (2) using a genetic algorithmthat finds at run-time nearly-optimal configurations using the informationprovided by the variability model. We also specify a case studyand we use it to evaluate our approach, showing that it is efficient andsuitable for devices with scarce resources.
