Towards Blockchain-Based Resource Allocation Models for Cloud-Edge Computing in IoT Applications

Today, Blockchain technology is emerging to support high secured performance computing. To improve privacy and security factors of allocating, storage, and manage resources in edge computing, blockchain technology can be used to guarantee safe data transmission and communications in the Internet of Things (IoT). Due to the heterogeneity of resources to cover a range number of IoT applications, resource allocation has a key role in increasing the performance of the IoT systems in edge computing. Also, a blockchain-based resource allocation model can support Quality of Service for IoT applications to ensure a highly secured communication environment in edge computing. Therefore, to detect and analyze technical aspects and new research directions in this issue, this paper reviews different existing blockchain-based resource allocation models in cloud-edge computing. From the review papers, we had a very high rate of relevant publishes 2018 to 2020. The most published papers belong to IEEE with 21 published papers. After IEEE, ACM and Elsevier are the next publishers with 8 papers. The introduced approaches in reviewed papers are compared using some known measures such as time, latency, cost, service spread, storage, and delay. This review aims to classify the principles and technical aspects of blockchain-based resource allocation in cloud-edge computing.
