Implementation of semantic system in the smart home lights device based on agent

摘要

The IoT device provides the potential for obtaining data contextually, by observing and measuring the physical events occurring in the environment. Smart Home has excellent interest by IoT device developers. Using a semantic approach to data processing on IoT devices provides the ability to define, modify, and interpret better data. In this research uses Nodemcu ESP8266 as a microcontroller on sensor node and actuator node. Raspberry Pi3 is used as an agent that serves as a router and knowledge base. Both devices already support wifi connectivity to facilitate the communication process. The sensor node is responsible for collecting data derived from the sensors process of the sensor module, the data obtained is sent to the agent to be initialized and inserted into the ontology. The agent performs the reasoning process to change existing data on the ontology according to the rule created and produce more representative and contextual data. The Actuator node performs a query against the current status of the light on the ontology as a reference for the action of switching on or off the light. Smart home with the semantic approach was implementation in the form of lights on and off control system.
