The Industrial Internet of Things collects data from the environment to improve industrial processes. Data integrity, privacy, authorisation, and authentication attacks are among the security vulnerabilities in traditional IIoT networks. Blockchain is a potential solution to some of these security issues. However, the throughput of traditional bloc...
Efficient blockchain querying is crucial for unlocking the full potential of blockchain technology in diverse applications and enabling it to compete with traditional databases in data management. This
paper comprehensively analyzes existing literature and presents a taxonomy of state-of-the-art techniques
employed to optimize query efficiency in b...
With its promise of transparency, security, and decentralization, blockchain technology faces significant challenges related to data storage and query efficiency. Current indexing methods, which often rely on structures like Merkle trees and Patricia tries, contribute to excessive storage overhead and slower query responses, particularly for full n...
Blockchain interoperability is one of the major challenges that has sprung up with the advancement of blockchain technology. A vast number of blockchains has been developed to aid in the continuous adoption of blockchain technology. These blockchains are developed without a standard protocol, therefore making them unable to interoperate with other...
In Africa, rapid population growth and a focus on increasing food production have often overlooked the crucial aspect of food
safety, leading to the highest per capita incidences of foodborne illness globally. This underscores the imperative to address the
food safety challenges on the continent. A critical concern is the widespread adulteration of...
This review paper delves into the global agricultural food supply chains through the lens of African perspectives, examining the role of blockchain and Internet of Things (IoT) technologies in transforming food traceability. It assesses the applicability and efficacy of these innovations in addressing critical issues such as food fraud, contaminati...
Concerns about food safety have grown across society in recent years. Building a trustworthy traceability system is essential for effectively identifying and preventing food safety issues as well as tracing the responsible parties. The entire food supply chain, which includes the stages of production, processing , warehousing, transportation, and s...
This paper discusses a feasible software solution that enables automatic marking and grading of scripts. Technology keeps expanding, and more advanced innovations are being implemented with time. The marking and allocation of grades for examination scripts through human efforts are gradually becoming a thing of the past. Hence, machines and softwar...
Blockchain technology has been increasingly adopted over the past few years since the introduction of Bitcoin, with several blockchain architectures and solutions being proposed. Most proposed solutions have been developed in isolation, without a standard protocol or cryptographic structure to work with. This has led to the problem of inter-operabi...
Blockchain-IIoT integration into industrial processes promises greater security, transparency, and traceability. However, this advancement faces significant storage and scalability issues with existing blockchain technologies. Each peer in the blockchain network maintains a full copy of the ledger which is updated through consensus. This full repli...
Since the inception of blockchain-based cryptocurrencies, researchers have been fascinated with the idea of integrating blockchain technology into other fields, such as health and manufacturing. Despite the benefits of blockchain, which include immutability, transparency, and traceability, certain issues that limit its integration with IIoT still l...

Supermarket shopping is an essential part of the livelihood of most people around the world. Consumers can acquire items essential for their daily activities. However, in an ever-evolving world with an increasing population and increasing crime rates, supermarket theft is becoming a prevalent problem with supermarket owners spending large sums of m...
Facial emotion recognition (FER) forms part of affective computing, where computers are trained to recognize human emotion from human expressions. Facial Emotion Recognition is very necessary for bridging the communication gap between humans and computers because facial expressions are a form of communication that transmits 55% of a person's emotio...
The increase of the Internet of Things (IoT) calls for secure solutions for industrial applications. The security of IoT can be potentially improved by blockchain. However, blockchain technology suffers scalability issues which hinders integration with IoT. Solutions to blockchain’s scalability issues, such as minimizing the computational complexit...

Digitization and automation have engulfed every scope and sphere of life. Internet of Things (IoT) has been the main enabler of the revolution. There still exist challenges in IoT that need to be addressed such as the limited address space for the increasing number of devices when using IPv4 and IPv6 as well as key security issues such as vulnerabl...
There are currently over 7.6 billion mobile phone connections in the world, which is approximately equivalent to the world’s population; as if to say that everyone in the world is hooked up to mobile telephony. By the next decade, it is estimated that the number of mobile phone subscribers would increase by a billion with 90% of this growth coming...

Current trends have proven that services provided by Electronic Government (e-Government) are helpful in the
realization of good governance objectives. These e-Government services leverage on modern Information and
Communication Technologies to provide an effective electronic public administration platform through which citizens and a
government’s...
From the recent upsurge in electric energy demands, most developing countries in Africa are often plunged into extended seasons of energy crises. A great deal of these crises results in crippling these economies as well as increasing poverty. To address the crises would mean to pump in more capital resources into the energy sector. Bearing in mind...
Electrical energy (electricity) has become an indispensable asset in building sustainable economies and reducing poverty. For such reasons many countries have embarked on various electrification projects, from urban areas to rural areas. However, these projects would not achieve the earlier stated objectives where there is unreliable supply of elec...
