Towards Requirements Engineering Process for Self-adaptive Embedded Systems

At present, there are a large number of embedded systems (ES) which need to modify their behavior at run time in response to changing environmental conditions (sensor failures, noisy networks, malicious threats, unexpected input. etc.) or in the cases where the requirements themselves needs to change. i.e. ES require self-adaptive capabilities. This kind of ES has been widely used in different domain, for instance in the smart home systems, automotive systems, telecommunication systems, environmental monitoring and others. Unfortunately, up to now, there are few researchers which interest for the high level design process of the self-adaptive embedded systems (SAES) specifically in the field of requirement engineering (RE). For this reason, the objectives of this paper is to try as much as possible to recall and compare between existing works build around the RE of SAES in the sake of identifying advantages and weak points of each work.
