**6. Evaluation of fog computing resources monetization architecture**

Fog computing is well known for making cloud processing, storing, and computational ability available at the network edge through fog nodes. Therefore, enabling cloud abilities to be carried out from end devices to nearby fog nodes, hence high computational power and low latency are achieved simultaneously. Fog architecture performs a huge role in fog computing. In most related works, the fog computing architecture is described as the structure shown in **Figure 1** [25, 38–40].

This structure involves an end device communicating with the fog nodes and clouds to request or send data for processing or storage. The monetization aspect of this architecture introduces a fourth block, either a third-party operator or a smart contract. Fog node resource monetization varies according to the literature. In this work, the architecture based on the monetization and pricing model employed is divided into two, namely:

I.Centralized monetization architecture

II.Decentralized monetization architecture
