Abstract Blockchain technology has been increasingly adopted over the past few years since introduction of Bitcoin, with several blockchain architectures and solutions being proposed. Most proposed have developed in isolation, without a standard protocol or cryptographic structure to work with. This led problem interoperability, where running on different platforms are unable communicate, limiting scope use. With blockchains variety fields such as Internet Things, it is expected that...
Digitization and automation have engulfed every scope sphere of life. Internet Things (IoT) has been the main enabler revolution. There still exist challenges in IoT that need to be addressed such as limited address space for increasing number devices when using IPv4 IPv6 well key security issues vulnerable access control mechanisms. Blockchain is a distributed ledger technology immense benefits enhanced traceability. Thus, blockchain can serve good foundation applications based on...
Distributed denial of service (DDoS) attacks are a major threat to any network-based provider. The ability an attacker harness the power lot compromised devices launch attack makes it even more complex handle. This complexity can increase when several attackers coordinate on one victim. Moreover, these days do not need be highly skilled perpetrate attack. Tools for orchestrating easily found online and require little no knowledge about scripts initiate Studies have been done severally...
ABSTRACT Wounds contribute to 30%–42% of hospital visits and 9% deaths but remain underreported in Africa. Diseases surgeries increase wound prevalence, especially rural areas where 27%–82% people live, health facilities are poor or non‐existent. This research aims design a disease‐related classification model for online diagnosis telemedicine support traditional practitioners village workers. paper focuses on wounds from diabetic ulcers, pressure surgery, venous ulcers. The approaches used...
ABSTRACT Reactive and preventive maintenance strategies have been applied to avert transformer failures safeguard their operations. However, these approaches limitations of high operational downtimes, over‐ under‐maintenance issues, fatigue revenue loss. The advancements in machine learning artificial intelligence positively altered the equipment landscape. Thus, predictive (PdM), contrast above‐listed approaches, has laid foundation for improving by identifying incipient solve existing...
Abstract The integration of Internet Things devices onto the Blockchain implies an increase in transactions that occur on Blockchain, thus increasing storage requirements. A solution approach is to leverage cloud resources for storing blocks within chain. paper, therefore, proposes two solutions this problem. first being improved hybrid architecture design which uses containerization create a side chain fog node connected it and Advanced Time-variant Multi-objective Particle Swarm...
Blockchain-IIoT integration into industrial processes promises greater security, transparency, and traceability. However, this advancement faces significant storage scalability issues with existing blockchain technologies. Each peer in the network maintains a full copy of ledger which is updated through consensus. This replication approach places burden on space peers would quickly outstrip capacity resource-constrained IIoT devices. Various solutions utilizing compression, summarization or...
Abstract Energy profligacy and appliance degradation are the apex reasons accounting for continuous rise in power wastage high energy bills. The decline conservation management residences has been largely attributed to financial implications of using intrusive methods. This work aimed resolve challenges load monitoring by introducing artificial intelligence machine learning optimise monitoring. To solve this challenge, a non‐intrusive approach was proposed where modalities prediction...
In Ghana and many countries within Sub-Sahara Africa, Long Term Evolution (LTE) is being considered for use the sectors of Governance, Energy distribution transmission, Transport, Education Health. Subscribers Governments region have high expectations these new networks want to leverage promised enhanced coverage data rates development. Recent performance evaluations deployed WiMAX in showed promising a wireless broadband technology supporting capacity demands needed peculiar Sub-Saharan...
The increase of the Internet Things (IoT) calls for secure solutions industrial applications. security IoT can be potentially improved by blockchain. However, blockchain technology suffers scalability issues which hinders integration with IoT. Solutions to blockchain’s issues, such as minimizing computational complexity consensus algorithms or storage requirements, have received attention. realize full potential in IoT, inefficiencies its inter-peer communication must also addressed. For...
Since the inception of blockchain-based cryptocurrencies, researchers have been fascinated with idea integrating blockchain technology into other fields, such as health and manufacturing. Despite benefits blockchain, which include immutability, transparency, traceability, certain issues that limit its integration IIoT still linger. One these prominent problems is storage inefficiency blockchain. Due to append-only nature growth ledger inevitably leads high requirements for peers. This poses...
