Non-functional requirements elicitation for edge computing

The proliferation of the Internet Things (IoT) devices and advances in their computing capabilities give an impetus to Edge Computing (EC) paradigm that can facilitate localize data storage. As a result, limitations like network connectivity issues, mobility constraints, real-time processing delays, Cloud be addressed more efficiently. EC create lot opportunities across breadth IT domains cyber–physical systems. Several studies have been conducted describing general requirements, challenges, issues. However, considering complexity involved paradigm, non-functional requirements (NFRs) are equally important as functional thoroughly investigated. This paper discusses NFRs, namely, performance, reliability, scalability, security assist maturing paradigm. To accomplish objective, available case state-of-the-art related real-world challenges concerning reviewed. Ultimately, anatomizes aforementioned NFRs leveraging six-part scenario form source-stimulus-artifact-environment-response-response measure assert Quality Service (QoS) EC.
