Data aggregation processes: a survey, a taxonomy, and design guidelines

Internet of Everything (IoE) Taxonomies: A Survey and a Novel Knowledge-Based Taxonomy

“…IoT processing of sensing data streams provides ubiquitous sensing services [ 42 , 102 , 106 ]. Data aggregation processes are vital for improving the quality of the designed system [ 107 ]. Big data technologies assist in data processing [ 76 ], the uncovering of new and valuable insights and information from incorporated data sources [ 28 , 69 ], and in improving prediction and decision-making [ 102 ].…”

“…Interaction between IoE smart devices can influence the service’s response time to end-users. The time interval between the initiation and the conclusion of the task is the response time [ 49 , 107 , 109 ].…”

“…The time dimension depends on how sensors are requested or provide data to the system in specific periods or on an ad-hoc basis (as software system makes a request), which is characterized as the following two distinct methods that were proposed in [ 107 ]: Pull method: The software component in the control of obtaining sensor data from sensors makes a requisition periodically (after specific intervals) or instantly obtains sensed data [ 107 ]. Push method: The physical or virtual sensor pushes data to the software component in the control of obtaining sensor data periodically [ 36 , 107 ]. In many cases, a sensor observation can be the result of a local sensor data fusion [ 68 ].…”
