Smart home technology comprises of multiple devices communicating with each other and human occupants to provide state of the art living conditions. The increased use of smart devices in smart homes, increases the rate of energy consumption. Among the plethora of smart devices within a smart home, one of the key smart devices that account for high data volume and rate of data transmission is the Closed-Circuit Television (CCTV) surveillance system. Furthermore, there has been multiple attempts by researchers to use Cloud computing solution to address the issue of storage and processing capabilities. However, the use of Cloud computing has challenges such as energy consumption, latency, and network bandwidth usage bottlenecks with energy cost set to increase by April 2022. The introduction of Fog computing as a solution aim to address existing Cloud computing issues such as energy consumption, latency, and network bandwidth usage, providing improvements to mobility, security and on demand requests. In this paper, Fog computing will provide a method that supports the management of data generated by CCTV camera system while reducing the energy consumption, latency, and network bandwidth usage. The work presented in this paper demonstrates efficiency and optimisation of energy consumption, latency, and network bandwidth usage using iFogSim2 network simulation toolkit. A comparison and interpretation of results from the iFogSim2 output for Cloud and Fog based scenarios is used to evaluate improvements in energy consumption, latency, and network bandwidth usage demonstrating the benefits of Fog based scenario to efficiently manage data from the CCTV camera system.
This article describes the importance of System Thinking (ST)/System Dynamics (SD) in addressing the complex sustainable energy planning issues with special focus to Developing Economy (DE). Many DE are undergoing dramatic changes in socioeconomic policies such market liberalisation, financing and the incorporation of grounded externalities such as the environmental implications of energy projects. The article articulates the inherent limitations of traditional energy planning tools and reviews the underlying dynamics of Sustainable Energy Development (SED) in the DE. It argues that the traditional energy policy formulation that focuses on the present decision without identifying how past policies created the present complexities fail to guide future decisions. It position that the past energy development trends witnessed in the developed nations contradict the notion of SED. The major impediments to SED in the DE are inappropriate technology; complex social organisation; environmental (energy) and resource degradation, inadequate and confused investment directions amongst others. The proposed methodological approach analyses the dynamic forces that impinge on energy systems and seeks to improve the decision making process. This article fills an important gap in the literatures by pinpointing the pertinent issues that need addressing for SED in the DE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
