Blockchain is a key technology that enables cryptocurrencies such as Bitcoin, Litecoin, etc. In recent years, researchers have ventured into tapping the potential of blockchain‐based ecosystems beyond cryptocurrencies. This paper explores the convergence of blockchain with the Internet of things (IoT) and its improved versions like software‐defined network (SDN)–based IoT, which are upcoming technologies in the area. This paper gives a brief description of the IoT and its challenges, especially the security aspects. It also discusses how blockchain concept can further resolve these challenges on the SDN‐based IoT platform. This paper first discussed the evolution of conventional IoT to the SDN‐based IoT, which can resolve many drawbacks of a conventional IoT system. Also, it is focused on how the concept of blockchain can be converged with SDN‐based IoT system to further improve its security aspects. Although the convergence of these different technologies has resulted into many advantages, many associated challenges still remain. This paper highlighted these challenges and opportunities to discover many other research issues that need to be resolved. The details of current literature on the same issue has also been highlighted in this paper.

“…The blockchain technology is being used in different application domains beyond the cryptocurrencies, e.g., SDN, Internet of Things, Fog computing, etc. [107]. To developing a machine learning and blockchain-based solution for authenticating mobile IoT devices, we have to take in mind the specific requirements of the blockchain, e.g., 1) when IoT data needed to be checked by the IoT entities without any central authority, 2) the ledger copies are required to be synchronized across all of the IoT entities · etc.…”

Bio-features are fast becoming a key tool to authenticate the IoT devices; in this sense, the purpose of this investigation is to summaries the factors that hinder biometrics models' development and deployment on a large scale, including human physiological (e.g., face, eyes, fingerprints-palm, or electrocardiogram) and behavioral features (e.g., signature, voice, gait, or keystroke). The different machine learning and data mining methods used by authentication and authorization schemes for mobile IoT devices are provided. Threat models and countermeasures used by biometrics-based authentication schemes for mobile IoT devices are also presented. More specifically, We analyze the state of the art of the existing biometric-based authentication schemes for IoT devices. Based on the current taxonomy, We conclude our paper with different types of challenges for future research efforts in biometrics-based authentication schemes for IoT devices.

“…Incorporating all the Blockchain features in a sensor network may not be realistic due to limited battery life, computation power and storage unless an efficient framework and techniques are adopted. The challenges and issues faced by the Internet of Things network are also addressed in [25]. The time complexity of MD5 and SHA-256 is (N ) and in terms of computation time, MD5 takes lesser time compared to the SHA-256 [26].…”

The need for sensors to deliver, communicate, collect, alert, and share information in various applications has made wireless sensor networks very popular. However, due to its limited resources in terms of computation power, battery life and memory storage of the sensor nodes, it is challenging to add security features to provide the confidentiality, integrity, and availability. In order to communicate reliably with trust and authenticity, providing data and system security especially for those sensors dealing with sensitive data related to healthcare, military activity, environmental sensing for weather prediction or seismic data etc. is vital. Blockchain technology ensures security and avoids the need of any trusted third party for security. However, applying Blockchain in a resource-constrained wireless sensor network is a challenging task because Blockchain is power, computation, and memory hungry in nature and demands heavy bandwidth due to control overheads. In this paper, a new routing and a private communication Blockchain framework is designed and tested with sensors generating constant and continuous data (like voice and video). However, it is realized that even if computation and bandwidth requirements are taken for granted, storage and battery life will cripple the sustainability of Blockchain application in sensor networks especially for high data generating sensors. The proposed Load Balancing Multi-Hop (LBMH) routing shares and enhances the battery life of the Cluster Heads and reduce control overhead during Block updates, but due to limited storage and energy of the sensor nodes, Blockchain in sensor networks may never be a reality unless storage and battery life of sensor devices are not limited on the one hand and computation power and bandwidth availability are high, on the other.
