Requirements Metamodeling for Self-Adaptive Embedded Systems

Abstract

Embedded systems (ES) ubiquity has increased in the last two decades; it is seldom to find any electronic device that is not controlled by ES. Additionally, there are a large number of ES which need to modify their behavior at run time in response to changing environmental conditions or in the cases where the requirements themselves need to be changed. Up to now, few researchers are interested in the high-level design process of the self-adaptive embedded systems (SAES) specifically in the field of requirement engineering (RE). While there exit some metamodels on RE for SAES, to the best of the authors' knowledge, there is no comprehensive metamodel that can be used as a reference for the development of RE for SAES. For this reason, the objectives of this paper are twofold, first, to review the literature state of the art and practice of requirements engineering for self-adaptive embedded systems and secondly to propose a complete metamodel (MM4SAES) that defines all concepts and relationships that must be taken into account in the development of SAES
