The Study in Edge IOT Era: A Software Framework Based on the Knowledge

In order to solve the inadaptability of traditional software and utilize the computing resources of edge nodes in the future Edge IOT Era, the paper analyzes the characteristics of IoT software and puts forward a new distributed knowledge framework. In this study, we introduce knowledge base into the normal wireless node and translate Wireless Sensor and Actor Network (WSAN) topology along with the software logic into knowledge for it. Moreover, seven heuristic rules are proposed in the process of design, based on experience, including node selection criterion and node collaboration mechanism. Finally, the proposed framework is illustrated and evaluated with a small greenhouse scenario.
