Modeling and simulation of web-of-things systems part 1: sensor nodes

In the Web of Things (WoT), special communication networks composed of sensor nodes, actuator nodes and service nodes form the basis for new types of web application systems, which are directly connected to the real world via sensors and actuators. The simulation of a WoT system allows evaluating different design options. It may require supporting “hardware in the loop”, “software in the loop” and “humans in the loop”. We propose several elements of a conceptual framework for simulating WoT systems at the application level, focusing on the simulation of three simple types of sensors. Our conceptual framework includes an ontology of WoT systems as sensor/actuator systems, and a meta-model for defining a WoT simulation language.
