Currently there are several Application Layer protocols running on Internet of Things system. Protocols such as MQTT, CoAP, XMPP, and DDS have different architectures and performance. Wireless sensor networks operating in low power, low bandwidth and with limited reliability, is more suitable to use CoAP. However, CoAP is inferior to MQTT architecture in terms of scalability. Therefore this research focuses on CoAP Broker implementation of an IETF draft which enables MQTT-like architecture to be implemented in CoAP. This research aims to implement an Access Gateway with the proposed protocol and show its use-case in poultry farm, involving sensor monitoring and actuator controls on multiple location. The result of this research shows the success of CoAP Broker implementation along with the mentioned use-case and the performance evaluation which has not indicate any congestion when handling 130 requests per second and good error-rate with low value between 0.01% - 0.04%.
