A Goal-Oriented Requirements Engineering Approach for IoT Applications

Requirements Engineering of IoT systems has the twin objectives of specifying functionality as well as communication objectives of the system. Existing goal-oriented and use case approaches were not developed to bring out communication objectives of systems. Consequently, when these techniques are applied then communication remains subordinate to functionality. We integrate both objectives in the notion of a GOT, GOal of Things. The GOT model represents the structure of GOTs and an instance of this model is the requirements specification of an IoT. The accompanying GOT Process provides three ways of GOT reduction. We illustrate its application to an Accident Reporting System. The GOT proposal is compared with a use-case oriented approach and a goal oriented approach.
