Container-based fog computing architecture and energy-balancing scheduling algorithm for energy IoT

One way of doing it is using data from wearables, blood glucose monitors, and other health apps to look for signs of bodily distress. This data should not face any latency issues as even a few seconds of delay can make a huge difference in a critical situation, such as a stroke. Traffic signals automatically turn red or stay green for a longer time based on the information processed from these sensors. The temperature recording can be pushed to the cloud every second with a service checking for fluctuations. But a more intelligent way of storing this information would be to check if there have been any temperature changes in the last few seconds.

Even if it is found that the university lags IT experts can also use fog computing technology in their education IoT . In order to build sub network, individual smart objects are linked up to fog edge nodes. For building time to time communication fog computing has to be implemented in education IoT system. In the design and development process of fog computing solutions for the Industrial Internet of Things , we need to take into consideration the characteristics of the industrial environment that must be met. These include low latency, predictability, response time, and operating with hard real-time compiling.

Dynamic compressive wideband spectrum sensing based on channel energy reconstruction in cognitive internet of things

The robust increase of Cloud-based healthcare IoT applications leads to the consumption of amount huge energy. According to energy efficiency direction, Isa et al. proposed a fog computing-based architecture for healthcare IoT applications to saving and optimise energy consumption. Specifically, they proposed an efficient energy fog-based computing model, called EEFC to optimize the location and number of fog servers at the edge layer. Experiment results demonstrated the efficiency of the proposed solution compared to existing cloud-based solutions when it saving energy up to 36% and 52%, respectively with low and high data speed scenarios.

• However, using VMs as the resource is not adaptable to fog computing platforms.
• Usually, data that isn’t required at the user proximity is stored in a cloud layer.
• Finally, the cloud layer or the data centre’s layer is regarded as IoT architecture’s topmost layer.
• In order to provide onsite technology that can scale up and down according to college requirements fog computing enables important micro data facilities.
• Sometimes, waiting for a node to free up may be more expensive than hitting the cloud server.

Fog nodes are computational resources deployed in a geographically distributed way, near the network edge. Either way, fog nodes can be seen as small data centers near the network edge that serve end devices in their vicinity. Fog computing is becoming a popular paradigm for bringing the advantages of the cloud nearer to the network edge. This way, computational tasks can be offloaded from end devices to nearby fog nodes, thus benefiting from high computational power and low latency at the same time. However, a closer look reveals that different papers use the term “architecture” for very different concepts.

Physical & virtual nodes (end devices)

The proposed solution is based on the Xilinx Zynq UltraScale+ MPSoC ZU3EG A484 SoC that has Quad-core ARM® Cortex™-A53 MPCore™, Dual-core ARM Cortex-R5 MPCore™. The practical implementation of the fog/edge node was performed on CANOpen fieldbus in two fog vs cloud computing variants. In the first variant, the driver for the CANOpen fieldbus is implemented on the ARM Cortex A53 core under a Linux operating system. In the second variant, the ARM Cortex R5 core is used to deal with the communication on the CANOpen fieldbus.

It is basically like a local computing but operated from a remote facility which can have the necessary efficiency, integrity, and information facility. For the fieldbus drivers layer, we defined a standard software interface used by the fog computing & services layer to instantiate these drivers and to exchange data with the devices connected to the fieldbuses. In addition, the fog computing & services layer has a standard interface that it is used by the cloud and middleware layer. After defining these specifications, we proceed to the software design of the fog node.

Challenges and future research directions

The word ‘fog’ relates to the cloud-like properties in the architecture, with devices generating large volumes of raw data. Instead of sending all of this data to the cloud for processing, fog computing does as much processing as it can by using computing units within the data-generated devices. These huge numbers of IoT devices at home, smart city municipalities, and industries will require petabytes of internet bandwidth if they plan to work on cloud computing infrastructure. In fog computing, data analysis does not involve moving the data into a cloud server. Therefore, there is no need for an extensive amount of network bandwidth.

Figure 3b shows schematically how such a view fits into the proposed framework. In each dimension, the architecture may follow an established architectural style, independently https://globalcloudteam.com/ from the other dimensions. For example, each dimension may or may not follow the layered architecture style, independently from the other dimensions.

She is an Information Systems graduate from BITS Pilani, one of India’s top universities for science and technological research. Her expertise in the industry has been fueled by stints in large corporations such as Goldman Sachs. She currently develops technology content for startups and tech communities. The increased amount of hardware may quickly lead to a certain amount of overlooked extra energy consumption. Appropriate measures such as ambient cooling, low-power silicon, and selective power-down modes need to be implemented to maintain energy efficiency.

The response time in fog computing is lesser than any other immediate technologies. It reduces the required bandwidth and also reduces the back and forth communication present between cloud and sensors that may negatively impact the performance of the Education IoT system . The net amounts of information sent in the cloud get reduced in fog computing .

Hierarchical Architecture Model

In addition to this the paper has also provided a methodical review for the purpose of depicting the methods that are essential for analysing the features related to fog computing. Thus, it can be concluded that with the help of this survey paper it will become easy to carry out the future research. In recent years, fog computing has emerged as a promising new paradigm for offering computation and storage services in a distributed way .
