    The rise in popularity of mobile devices has been made possible
    due to advances in processing power and the miniaturization of
    modern processors. Mobile devices are often embedded systems
    with limited resources such as battery, processing power, and memory,
    which impact the user experience. These devices located at
    the edge of the network can also generate large amounts of data,
    which makes it difficult to centralize the data in the cloud. To address
    the scalability issues, fog computing is used to intermediate
    storage and communication services between cloud computing and
    end devices, allowing for decentralized and scalable data. In fog
    computing, a message server may be used to distribute information
    through one or more communication channels, reducing computational
    resources. To transmit messages, it is necessary to choose
    a communication protocol, and it is important to consider the limitations
    of mobile devices when analyzing the behavior of fog
    communication protocols. This paper evaluates the performance
    of three fog computing protocols: MQTT, AMQP, and STOMP. Results
    indicate that MQTT achieves the best performance in terms
    of power and processing consumption, AMQP has lower memory
    usage, and STOMP has a shorter round trip time for each message.
