One of the important factors affecting communication performance in the Internet of Things is the messaging protocol. MQTT, XMPP and AMQP are centralized application protocols that communicate through the server. DDS and CoAP are application protocols that can communicate directly, especially in real-time applications. As the Internet of Things is becoming more widespread and usage scenarios have different requirements, new approaches to data communication are required. In this study, a UDP based hybrid application layer protocol has been designed which can communicate both directly and through central server. In addition, operating logic and packet structure of the developed hybrid protocol is examined.
