We are privileged to be alive in the times of science and technology that has exposed us to further innovations. Human depravity and heights of wisdom do not end where we stand today. It still has to find the abyss and produce wonders that shake the world altogether. Edge Computing is one such future technology that is poised to act as the solution to the conflict-ridden networking world. The basis of edge computing revolves around the concept of networking, computation, and storage closer to its groundwork.
The increase in autonomous high-bandwidth experiences can only be fulfilled with this. When joined with 5G, edge computing is going to bring tremendous opportunities and applications in almost every industry.
Edge Computing in Simple Language
Let’s first define Edge Computing from the point of Gartner Research experts. According to them edge computing is the processing of information near to the edge- a single point where that information is consumed and produced. Unlike cloud computing that puts storage and computation thousands of miles away from the device they are gathering, edge computing brings all of these closer.
The cloud resources are bound to become physically close to the source through edge computing to ensure low latency. So is it the end of cloud computing? Only the opposite. Cloud is going to come closer to you now. The centralized approach of this computing will allow the IoT devices to process data on itself.
Role of Edge Computing in 5G
Edge capabilities are going to become a fundamental part of enterprise & IoT services. They will be mostly relying upon the mentioned computing and 5G is predicted to make up one-fifth of the mobile data traffic in three years. The seamless integration of both is going to process huge amounts of data in real-time. Edge computing consummates the condition of sub-millisecond imposed by 5G applications. The energy spent in the process is at least five times lesser than that of cloud access.
Requirements of Edge Computing in 5G
According to researchers, to successfully deploy and operate edge computing in 5G, four requirements are to be met.
● Real-time Interaction
This is the main attraction of edge computation as opposed to cloud interaction. The real time interaction is the basis of low latency and ensures the smooth working of related applications to improve QoS. Decision making and data analysis services also find real-time implications with edge.
● Local Processing
Local processing is made possible with edge computing as the information is processed and consumed at the edge. With low traffic between the core network and a minor cell, higher connection bandwidth can be achieved. This also reduces traffic through core networks.
● Optimized Data Rate
Applications like virtual reality and remote surgery generate a massive amount of data. Data rate has to be high in order to transmit such a range of data to the edge cloud. Edge computing works with edge servers to allow seamless connection with the edge clouds. Edge servers can be embedded in BSs. The whole process does not require the access of the core network.
● High Availability
The fourth requirement is the high availability that makes the cloud services available at the edge. With edge computing, data and application logic are pushed towards the edge cloud, hence the need for high availability of edge cloud.
Applications of Edge Computing 5G
End user is brought closer to the large servers and cloud with edge computing. This makes edge computing find applications in the most complicated fields. Some of those applications are discussed as these:
Remote operations in the field of medicine such as surgery, diagnostics, monitoring of patient’s vitals remotely will benefit a lot from this technology. Even the surgical tools can be controlled and used from a distance in critical conditions. In situations like today as corona strikes, the medical field can achieve safety and comfort too.
● Virtual Reality/Augmented Reality/Mixed Reality
The streaming of content through virtual reality glasses that are very big for the eyes. This can be reduced to even lens size once the computation is brought to the edges.
● Tactile Internet
This is the future of the internet. Tactile internet will have a very short response time even less than a millisecond. Edge computing and 5G will make this possible by reducing the computation time. The internet will be ultra-responsive and ultra-reliable. Real-time control messages will be the easiest thing and will also ensure physical tactile experiences from miles away.
● Internet of Things
The Internet of Things (IoT) will see new heights. Appliances like kitchen necessities and other household appliances will also work with the internet and will be controlled remotely
Data management is going to get improved with the trend of edge computing and the introduction of 5G. The peak traffic demands, response time, bandwidth consumption, higher processing costs, all of such problems are coming to an end. 5G and Edge computing provide local computation and improve QoS as well as resource management. It strengthens network control and achieves a flexible network control. This architecture also attains low latency and close proximity by splitting the tasks and offloading them on one server.
Deploying edge computing in 5G can also face some challenges that include network vulnerability, heterogeneity, and standardization that are to be addressed before going into this future’s star. Although we found many benefits of the deployment of these two technologies, our belief is that it is also going to bring certain challenges. These challenges have to be addressed in the near future or the revolution is going to get postponed.
