Internet of Things-aided Smart Grid: Technologies, Architectures, Applications, Prototypes, and Future Research Directions
Traditional power grids are being transformed into Smart Grids (SGs) to
address the issues in existing power system due to uni-directional information
flow, energy wastage, growing energy demand, reliability and security. SGs
offer bi-directional energy flow between service providers and consumers,
involving power generation, transmission, distribution and utilization systems.
SGs employ various devices for the monitoring, analysis and control of the
grid, deployed at power plants, distribution centers and in consumers' premises
in a very large number. Hence, an SG requires connectivity, automation and the
tracking of such devices. This is achieved with the help of Internet of Things
(IoT). IoT helps SG systems to support various network functions throughout the
generation, transmission, distribution and consumption of energy by
incorporating IoT devices (such as sensors, actuators and smart meters), as
well as by providing the connectivity, automation and tracking for such
devices. In this paper, we provide a comprehensive survey on IoT-aided SG
systems, which includes the existing architectures, applications and prototypes
of IoT-aided SG systems. This survey also highlights the open issues,
challenges and future research directions for IoT-aided SG systems
Mobile Commerce and Applications: An Exploratory Study and Review
Mobile commerce is enabling the development of additional revenue streams for
organizations through the delivery of chargeable mobile services. According to
the European Information Technology Observatory, the total amount of revenue
generated by mobile commerce was reported to be less than {\pounds}9 million in
the United Kingdom in 2001. By 2005 this had, at least, doubled and more recent
industry forecasts project significant global growth in this area. Mobile
commerce creates a range of business opportunities and new revenue streams for
businesses across industry sectors via the deployment of innovative services,
applications and associated information content. This paper presents a review
of mobile commerce business models and their importance for the creation of
mobile commerce solutions.Comment: Journal of Computing online at
