Dynamic Switching in the Measurements’ Collecting from Heterogeneous Data Sources

Abstract

The Data Stream Processing Strategy (DSPS) focus on online data processing based on IoT environments. Because of the IoT devices are possibly heterogeneous between them, the data gathering is coordinated through a measurement adapter (MA), who is responsible for data transmission to the data processor. In this work, measures’ indirect transmission is incorporated through measurement adapters, promoting cooperative behaviour and the interaction between them. This extends DSPS allowing direct and indirect data collecting. The new states and process view are analysed in terms of the MA. An enveloping strategy is introduced for verifying the data integrity in the transmission path. A simulation was carried out around the generated overhead with this kind of strategy in the MAs. A mean-time of 5.781 ms is obtained as overhead, which makes it feasible of application, considering that in another way the data would be lost, and the MA becomes uncommunicated.
