A critical analysis of research potential, challenges and future directives in industrial wireless sensor networks
In recent years, Industrial Wireless Sensor Networks (IWSNs) have emerged as an important research theme with applications spanning a wide range of industries including automation, monitoring, process control, feedback systems and automotive. Wide scope of IWSNs applications ranging from small production units, large oil and gas industries to nuclear fission control, enables a fast-paced research in this field. Though IWSNs offer advantages of low cost, flexibility, scalability, self-healing, easy deployment and reformation, yet they pose certain limitations on available potential and introduce challenges on multiple fronts due to their susceptibility to highly complex and uncertain industrial environments. In this paper a detailed discussion on design objectives, challenges and solutions, for IWSNs, are presented. A careful evaluation of industrial systems, deadlines and possible hazards in industrial atmosphere are discussed. The paper also presents a thorough review of the existing standards and industrial protocols and gives a critical evaluation of potential of these standards and protocols along with a detailed discussion on available hardware platforms, specific industrial energy harvesting techniques and their capabilities. The paper lists main service providers for IWSNs solutions and gives insight of future trends and research gaps in the field of IWSNs
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
A Systematic Literature Review on Task Allocation and Performance Management Techniques in Cloud Data Center
As cloud computing usage grows, cloud data centers play an increasingly
important role. To maximize resource utilization, ensure service quality, and
enhance system performance, it is crucial to allocate tasks and manage
performance effectively. The purpose of this study is to provide an extensive
analysis of task allocation and performance management techniques employed in
cloud data centers. The aim is to systematically categorize and organize
previous research by identifying the cloud computing methodologies, categories,
and gaps. A literature review was conducted, which included the analysis of 463
task allocations and 480 performance management papers. The review revealed
three task allocation research topics and seven performance management methods.
Task allocation research areas are resource allocation, load-Balancing, and
scheduling. Performance management includes monitoring and control, power and
energy management, resource utilization optimization, quality of service
management, fault management, virtual machine management, and network
management. The study proposes new techniques to enhance cloud computing work
allocation and performance management. Short-comings in each approach can guide
future research. The research's findings on cloud data center task allocation
and performance management can assist academics, practitioners, and cloud
service providers in optimizing their systems for dependability,
cost-effectiveness, and scalability. Innovative methodologies can steer future
research to fill gaps in the literature
