Industrial IoT has special communication requirements, including high reliability, low latency, flexibility, and security. These are instinctively provided by the 5G mobile technology, making it a successful candidate for supporting Industrial IoT (IIoT) scenarios. The aim of this paper is to identify current research challenges and solutions in relation to 5G-enabled Industrial IoT, based on the initial requirements and promises of both domains. The methodology of the paper follows the steps of surveying state-of-the art, comparing results to identify further challenges, and drawing conclusions as lessons learned for each research domain. These areas include IIoT applications and their requirements; mobile edge cloud; back-end performance tuning; network function virtualization; and security, blockchains for IIoT, Artificial Intelligence support for 5G, and private campus networks. Beside surveying the current challenges and solutions, the paper aims to provide meaningful comparisons for each of these areas (in relation to 5G-enabled IIoT) to draw conclusions on current research gaps.

“…The devices' ability to connect and communicate with each other without human interaction has enabled many conveniences for human in areas such as smart homes, smart vehicles, medical care, agriculture, manufacturing, and others [23]. In industrial settings, the integration of blockchain technology and the Industrial Internet of Things (IIoT) is bringing benefits to produce and manufacture goods with tight integrations between business partners [31].…”

Blockchain is a developing technology that can be utilized for secure data storage and sharing. In this work, we examine the cost of Blockchain-based data storage for constrained Internet of Things (IoT) devices. We had two phases in the study. In the first phase, we stored data retrieved from a temperature/humidity sensor connected to an Ethereum testnet blockchain using smart contracts in two different ways: first, appending the new data to the existing data, storing all sensor data; and second, overwriting the new data onto the existing data, storing only a recent portion of the data. In the second phase, we stored simulated data from several sensors on the blockchain assuming sensor data is numeric. We proposed a method for encoding the data from the sensors in one variable and compared the costs of storing the data in an array versus storing the encoded data from all sensors in one variable. We also compared the costs of carrying out the encoding within the smart contract versus outside the smart contract. In the first phase, our results indicate that overwriting data points is more cost-efficient than appending them. In the second phase, using the proposed encoding method to store the data from several sensors costs significantly less than storing the data in an array, if the encoding is done outside the smart contract. If the encoding is carried out in the smart contract, the cost is still less than storing the data in an array, however, the difference is not significant. The study shows that even though expensive, for applications where the integrity and transparency of data are crucial, storing IoT sensor data on Ethereum could be a reliable solution.

“…IoT devices that are capable to transfer and manipulate data, identify other devices are said to be Smart Devices. With Smart Devices in the IoT system, humans can use it to locate, track, identify, monitor and perform actions based on the input received [2]. These complexities of connecting and the communication between devices are not know to the end users and the network operations are also not known to them in the case of a Smart Home scenario.…”

“…Blockchain is an immutable decentralized ledger which store transactions which is done between two nodes on its linked list like structure with cryptographic hashes without the need of a third party to authenticate the transaction, thereby eliminating the need for a middleman. Initially blockchain was only used for cryptocurrency like Ethereum, Bitcoin etc., as the popularity grew many jumped on the bandwagon and started polluting them market with Initial Coin Offerings (ICOs) [2]. With all that pollution in the market there was disorder and confusion among the cryptocurrency providers which lead to the downfall.…”

This world always revolves around technology. There is always some disruptive technology that topples down any technology that people normally consider as a de-facto standard or norm. The Internet was one of these disruptive technologies which turned the whole way of how people were communicating with each other. It has revolutionized computing and communication. After a few decades of disruption, today people have accustomed to make their jobs easier with automation, remote control over the Internet, unsupervised actuation etc., This is all feasible with the advent of Internet of Things (IoT). IoT is one of the disruptive technologies of this era. Consumers of IoT are of different sorts ranging from, normal home automation to space engineering. These consumers share important details in these IoT networks which are susceptible to attacks from intruders who abuse the flaws of the IoT network for their own benefit. IoT security is one of the major concerns among all the issues of implementing an IoT based solution. Blockchain another disruptive technology is amalgamated to form a robust secure Smart Home Ecosystem. An Ecosystem is designed to incorporate IoT and Blockchain seamlessly. Where services could be automated and operated in a secure manner. This paper proposes the performance results of a Security framework for a Sustainable Smart Ecosystem using permissioned Blockchain.
