Wireless Sensor Network (WSN) has been used in various fields and for various applications that typically use the module NRF24L01. This includes environmental monitoring, volcanic activity monitoring, supporting components in order to provide a smart city, and monitoring activity in the agricultural field. The system on Wireless Sensor Network (WSN) designed in three main components: broker, publisher, and subscriber. As for a real-time communication system of WSN, an access method which is not dedicated for merely two communication devices is needed. Broker is supposed to handle some different communication data from publisher or subscriber and to ensure that the data transmitted among the three received at the destination. The basic question while designing a communication protocol for Wireless Sensor Network (WSN) is on how to coordinate the communication among Publisher, Subscriber and Broker. Generally, publish / subscribe on Wireless Sensor Network (WSN) using NRF24L01 are configured using the WiFi module with MQTT protocol in which each sensor node transmits data through the gateway and then to the server via the Internet. Thus, the WSN with the intranet or local network basis has no protocol for applying Publish/Subscribe without using MQTT protocol.
