This is definitely the main idea which modernized the terms edge computing to fog computing by SISCO . Fog applications might generate some real-time radio and network information that can offer a better analyzed experience to the user. This translated data is not only much responsive but also opens up new extension of opportunities. Big data analytics from fog computing can help to glean insights and also enable devices to make smart and inelegance based decisions without human interaction. The efficiency of data storing and data accessing becomes easier and quicker with enabling fog computing in the education IoT system. These days most of the higher institutions are implementing regular office applications, online desktop, messaging services to hold web level solutions for students and teachers much specifically.
The employees and the IT experts are barely expertized in the field of the technology. Not only that, the infrastructure in the education system is not that developed in majority of the institutions, thus training the teachers and other employees regarding the usage of the technology becomes very difficult. Education industry has the chances of encountering a wide number of obstacles that gives rich understanding towards the students.
Fog computing is defined by its decentralization of computing resources and locating these resources closer to data-producing sources. This data is converted into a protocol understood by internet-based service providers such as MQTT or HTTP. On November 19, 2015, Cisco Systems, ARM Holdings, Dell, Intel, Microsoft, and Princeton University, founded the OpenFog Consortium to promote interests and development in fog computing. Managing-Director Helder Antunes became the consortium’s first chairman and Intel’s Chief IoT Strategist Jeff Fedders became its first president.

Senior Editor Brandon Butler covers the cloud computing industry for Network World by focusing on the advancements of major players in the industry, tracking end user deployments and keeping tabs on the hottest new startups. Fogging enables repeatable structures in the edge computing concept so that enterprises can easily push compute power away from their centralized systems or clouds to improve scalability and performance. An example of how the sensor, edge, fog and cloud layers of a computing infrastructure connect.
But, imagine if you were constantly streaming complex information or large files, like images or video. The impact on bandwidth and latency could be massive depending on the application. https://globalcloudteam.com/ or fog networking, also known as fogging, is an architecture that uses edge devices to carry out a substantial amount of computation , storage, and communication locally and routed over the Internet backbone. Fog computing promises to create a more efficient system that reduces the number of resources necessary to transport data (since more of the data is processed at the ”edge” of a company’s network).
The initial benefit is efficiency of data traffic and a reduction in latency. By implementing a fog layer, the data that the cloud receives for your specific embedded application is a lot less cluttered. Where a cloud would have to first weed through a pile of unnecessary data before taking any action or returning results, it can now act directly upon the data that it receives from the fog layer. Where edge computing might send huge streams of data directly to the cloud, fog computing can receive the data from the edge layer before it reaches the cloud and then decide what is relevant and what isn’t.
By adapting fog computing technologies, you can build and deploy “smart” and efficient IIoT solutions in smaller steps. However, instead of thinking about “cloud vs. fog vs. edge,” you should reframe your thinking around the question, “Which combination is best suited for my particular needs? ” This way, it is not viewed as a “one or the other” decision, and rather as a collaborative adaptation of different technologies and architectures. Fog architecture is a model which comprises of a number of different layers. The architecture provides an overview of different functionalities that are performed by respective layers. The protocols used at different layers, the particular devices that are used at different layers and their functionalities, specifications are identified by going through the fog architecture.
What Is Fog Computing?
Load balancing LTE states with some complement of passive extents (e.g., RSRQ), throughput, dynamic analytics, and data mining might infer the number of resource blocks used state . The Edge Analytics software is typically deployed on an IoT gateway and processes the sensor data from multiple field units.

A method has been described, which can centralize the flooding strategies dynamically to save energy in assorted networks . Alternatively, Nishio et al. planned a framework for varied resource sharing of mapping heterogeneous resources like availability of CPU, high bandwidth, and better storage on fog nodes structure. Resource sharing optimization challenges can be proposed by utilization of service-oriented functions. Fan also defined challenges and the solution to measure the inclusive capability of information system to handle data including big data analytics, for effective information system as data storage, based on data analytics at the edge. Typically, public remote storage sensitive services and private cloud data centers could be compromised and leaked.
Fog computing deployments can help facilitate the transfer of data between where its created and a variety of places where it needs to go. Fog computing is the concept of a network fabric that stretches from the outer edges of where data is created to where it will eventually be stored, whether that’s in the cloud or in a customer’s data center. LILEE Systems’ new fog computing platform is well suited to distributed… As the technology is still in its emerging phase, this is one of the major issues.
Fog as a service is delivering an inspiring opportunity for educational service providers. Fog service providers in the FaaS platform create arrays of fog nodes with an option of offering them at geographic locations to provide particular services to several end-users . This could be beneficial for educational institutions that run a number of campuses in different locations. Accordingly, the technology of fog computing is considered as reliable architecture where data can be processed, analysed, and stored within the network through fog nodes instead of centralising data in the cloud. Table 1 compares fog computing and cloud computing to identify the areas of differences.

Fog based data access and analytics give a better alert about customer requirements, best position handling for where to transmit, store, and control functions throughout cloud to the IoT continuum. Applications, due to close proximity, at end devices provide a better conscious and responsive reproduced customer requirement relation . Edge computing lacks a complex hierarchy, as it is essentially one layer of nodes located near the user. Fog computing, on the other hand, has many intermediate layers between the edge computing and the central cloud, as seen in the above image. Any location in a network where the compute and other resources and services are available closer to the user than the central data center or cloud.
