MQTT-SN is a development of the widely used protocol on the Internet of Things Technology, MQTT. In common MQTT-SN protocol is same as well as MQTT, but MQTT-SN is focused on the sector of wireless sensor network. In MQTT-SN the most prominent is the presence of gateway. Gateway is used to collective data from multiple sensor nodes and forwarding data to broker server. Gateway is the most important part of MQTT-SN technology, because gateway is communicator between sensor node and broker server. Therefor availability of gateway is crucial when facing failure-system or down. This research will be focus on increasing the availability of MQTT server brokers and gateway by implementing Haproxy Load Balancer and Keepalived that installed on 3 Raspberry Pi's as gateways. This system also used multiple broker servers which sharing message or topic for improve availability on broker server side. Research results is brokers and gateways successfully improved availability by using clusterization, balancer traffic, multiple broker implementation and redudancy up to 100% when one of the gateway or broker has a failure.
