Query: A Scalable Architecture for Monitoring IoT Devices Using Ethereum and
  Fog Computing   With the recent considerable developments in the Internet of Things (IoT),
billions of resource-constrained devices are interconnected through the
internet. Monitoring this huge number of IoT devices that are heterogeneous in
terms of underlying communication protocols and data format is challenging. The
majority of existing IoT device monitoring solutions heavily rely on
centralized architectures. Since using centralized architectures comes at the
expense of trusting an authority, it has several inherent drawbacks, including
vulnerability to security attacks, lack of data privacy, and unauthorized data
manipulation. Hence, a new decentralized approach is crucial to remedy these
drawbacks. One of the most promising technologies which is widely used to
provide decentralization is blockchain. Additionally, to ease the burden of
communication overhead and computational power on resource-constrained IoT
devices, fog computing can be exploited to decrease communication latency and
provide better network scalability.
  In this paper, we propose a scalable blockchain-based architecture for
monitoring IoT devices using fog computing. To demonstrate the feasibility and
usability of the proposed solution, we have implemented a proof-of-concept
prototype, leveraging Ethereum smart contracts. Finally, a comprehensive
evaluation is conducted. The evaluation results indicate that the proposed
solution is significantly scalable and compatible with resource-constrained IoT
devices.
