    Green Information Technology (IT) Strategies in Institutions of Higher Learning in Kenya for Sustainability: Challenges and Opportunities
    (International Journal of Computer Science Trends and Technology, 2023-02-28) Kirui, Leonard K.; Wechuli, Alice Nambiro; Masinde, Eugene O.
    Green IT strategies refers to measures and steps of promoting environmentally friendly products and services towards reducing the levels of environmental degradation due to such as carbon emissions, air pollution, to combat effects of climate change. There is also the element of leverage on energy-efficient and cost-effective products and services. In this paper an attempt has been made to review previous literature related to the green IT strategies from the early phases of IT as a producer(device and data center) to the later strategic phases(with future technologies). Drivers of green IT strategies have also been explored and include: costs, regulatory and legal, social and political, new markets, self-drive and enabling business eco-system. Opportunities and recommendations on measures to be taken to enhance green IT strategies in IHL have also been discussed. To be able appreciate the drivers of green IT strategies, methodology adopted was that of qualitative content analysis. The aspects of availability of government goodwill, societal goodwill, market infrastructure, costs savings, human resource capacity, cultural shift, laid down government regulations and policies, provided nuances for green IT drivers. Support and adoption of green IT strategies as well as coming up with action plans and frameworks goes along in entrenching the green IT concept for environmental and socio-economical sustainability. There is little research and content on green IT strategies in Institutions of Higher Learning (IHL) in Kenya in terms of activities and institutional governance at the levels of operational, tactical and strategic. Perhaps, this is partly as result of weak link between national policies, institutional policies, and activities. The paper recommends re-configuring of Kenya government policies to better guide its institutions of higher learning in their role deliberated in responding to green IT strategies for sustainability.

    Leveraging P2P Architecture and Semantic Web for Enhanced Resource Discovery
    (International Journal of Scientific Research in Science, Engineering and Technology, 2024-05-18) Kirui, Leonard K.; Mbuguah, Samuel Mungai; Ronoh, Richard K.
    Web 4.0, also known as the next generation, intelligent internet, possesses the potential to become a widely and universally used communication medium for various types of information. However, its decentralized architecture lacks strong semantic support, resulting in an internet that is disorganized. The current system lacks the capacity to facilitate users' effective information discovery, extraction, and integration from multiple sources. Additionally, it fails to give consumers efficient tools for manipulating and turning acquired data into knowledge that is useful. Peer-to-peer (P2P) overlay technologies have recently come to light as a way to improve resource discovery on the internet. In dynamic and large- scale situations, these technologies provide a scalable framework for allocating, sharing, and gaining access to resources. The purpose of this research is to discuss on semantically enabled web architecture that makes use of P2P overlay technology. This architecture aims to facilitate structured and precise access to internet resources and promote knowledge sharing among community members who share similar interests. The paper examines the core elements of the semantic web architecture, which encompass the services and protocols responsible for resource advertising, discovery, and management, methods and material. It then delve into the hybrid peer-to-peer (P2P) overlay structure, specifically focusing on indexing and resource location, and explores the mechanisms necessary to facilitate scalable routing within a distributed environment.
