Systems, apparatus, and methods that can elect a broker on a Message Queuing Telemetry Transport (MQTT) bus are disclosed. One system includes an MQTT bus and a set of client devices on the MQTT bus. Each client device maintains a set of attributes for each other client device and casts one or more votes for a particular client device on the MQTT bus to elect the particular client device as a new broker on the MQTT bus in response to a current broker on the MQTT bus becoming unavailable. The votes cast for the particular client device are based on a first value corresponding to one or more attributes for the particular client device relative to respective second values to the corresponding attribute(s) for each of the other client devices on the MQTT bus as calculated by each respective client device on the MQTT bus.
