  We analyze the utilization of publish-subscribe protocols in IoT and Fog
Computing and challenges around security configuration, performance, and
qualitative characteristics. Such problems with security configuration lead to
significant disruptions and high operation costs. Yet, These issues can be
prevented by selecting the appropriate transmission technology for each
configuration, considering the variations in sizing, installation, sensor
profile, distribution, security, networking, and locality. This work aims to
present a comparative qualitative and quantitative analysis around diverse
configurations, focusing on Smart Agriculture's scenario and specifically the
case of fish-farming. As result, we applied a data generation workbench to
create datasets of relevant research data and compared the results in terms of
performance, resource utilization, security, and resilience. Also, we provide a
qualitative analysis of use case scenarios for the quantitative data produced.
As a contribution, this robust analysis provides a blueprint to decision
support for Fog Computing engineers analyzing the best protocol to apply in
various configurations.
