An Improved RE Framewrok for IoT-Oriented Smart Applications Using Inetgrated Approach

Requirement engineering (RE) plays a vital part for developing proficient systems and a major cause of system failure is due to the flaws in the RE. Understanding requirements for developing a system is an essential task and requires domain expertise. Internet of things (IoT) is the emerging field consists of smart devices and sensors connected to the Internet where they communicate with each other in order to exchange data and information. RE community gives very less attention towards IoT domain. This research proposes an improved RE framework for IoT-based smart applications using integrated approach. The proposed framework addresses the challenges faced in the requirement development of smart applications using existing RE methodologies. The proposed framework is an integrated approach which is equipped with the emerging RE techniques in the context of IoT-based smart applications. The proposed framework is comprised of five different steps of RE which are embedded with set of verified RE techniques for efficient requirement management. The proposed framework is validated with a real-time healthcare IoT-based case study to verify and realize the applicability of proposed framework. It is revealed that the projected framework provides precious impending into the requirement management of IoT based smart applications.
