“…Since the information and communication technology has emerged information demands and analytics requirements, the data integration becomes an important issue in design and development of IoT systems. Especially for industrial applications, the integration process for data analysis is a hot topic in research, a study (Chen, ) illustrates this point and reviews the ideas and practices that facilitate the information integration process with ICT technologies. - Small to large scale: Since some of the studies on IoT (Piccialli, Chianese, & Jung, ; Rashidi, Cook, Holder, & Schmitter‐Edgecombe, ) attempted to provide an integrated service, how to combine multiple systems for a particular region has also become a research trend of IoT in recent years. A typical example is the smart home application (Rashidi et al, ), which is aimed to gather and integrate data coming from different types of sensors and devices as well as external systems.
