**10. Conclusion**

Fog computing has immensely alleviated the challenges faced by edge computing, and has introduced us to new possibilities we can achieve with real-time analysis. The application of fog computing is vast, ranging from health care, agriculture, sports, housing, computations, etc. Fog computing makes up all the deficiencies of IoT networks in computing and storage and reduces the latency in IoT-Cloud communication. Monetization of fog computing has been a major challenge since all participants seem not to be favored in any system of monetization. In this work, we surveyed the characteristics of fog computing, such as a large number of nodes, edge location, low latency, etc. We briefly explained the working relationships, the importance of each, and how fog computing brings cloud capabilities to the edge. We also explored the monetization architectures applied by various literature. We found in the study that the decentralization of the fog monetization architecture stands out since it solves some of the issues posed by centralized fog monetization architecture, such as QoS and additional fee costs by third parties payment gateway.
