SCHEME OF IOT MIDDLEWARE BASED ON MESSAGE SERVICE

Subscription-based message pushing can effectively reduce the processing pressure of data servers in the Internet of Things (JOT) system. This paper describes the architecture of an JOT middleware based on message service. The middleware integrates processing chips for data acquisition and Wi-Fi modules for networking. It provides hardware and software interfaces for locale applications and web services. Both debugging mode and working mode is supplied. Using this middleware to build an JOT system, the development cost will be greatly reduced. The stress testing of a module of middleware-based lighting landscape system is described. With 90 concurrent threads, the response speed and throughput are normal in a stable network environment. At the same time, using the web service framework nginx+ tomcat + microservice + zookeeper based on EMQTTD, a distributed system can be built easily by adding servers in a flat way, and cluster services be developed.
