Wireless Sensor Network is one of the right methods to be used as a monitoring system of a number of resources in buildings simultaneously and to get maximum information without having to be in the area of the building. The fundamental question when designing a communication protocol for wireless sensor network (WSN) is how the system of coordination between nodes, the effective solution to the problem of the coordination system is by providing nodes that use the publish / subscribe messaging system. This study discusses the application of internet of things on wireless building network based on NRF24L01 with publish / subscribe messaging system protocol. The discussion covers simulation, designing, implementation, application testing and system performance both work function and performance of each node. The results showed that the system is able to monitor all information and control the equipment of a building through the web interface facilitate the officer in the maintenance and supervision of a building, then for testing the prototype performance of the system obtained the conclusion that both in the process of publish and subscribe data the value of delay, throughput and packet Loss on each node is directly proportional to the size of the packet sent, the larger the packet sent the greater the value of time delay, throughput and packet Loss..
