What is Mobile Cloud Computing: Overview, Challenges and Scope

Playing PUBG, posting Instagram videos, using Google Docs, and watching a live cricket match on a smartphone, Mobile Cloud Computing made all these possible. MCC is like a magic wand that dispels all the technical barriers and gives you entertainment, communication, social life, storage, information & daily help. It quietly powers everything that we enjoy on our mobile devices. Huge amounts of data are transferred effortlessly in the blink of an eye via mobile devices.

Any individual using a mobile phone may not be aware of all the complex processes that take place within their mobile. Keeping the end user comfortable and free from all the technical hassles is what makes MCC remarkable. If you want to know what MCC is and how it differs from cloud computing, then we should start with its origins and delve into its architecture, challenges and scope to fully understand the computing model.

Overview of Mobile Cloud Computing

The evolution from Mainframes to MCC highlights the technical advancements over the past years. The introduction of the internet and mobile led to digitisation and advanced technologies such as 5G, cloud computing, and MCC.

What is Mobile Cloud Computing​ (MCC)?

MCC is a technology in which your mobile device (smartphone or tablet) uses cloud servers to perform tasks rather than doing everything on the device itself. MCC is essentially an extension of cloud computing, bringing cloud services to mobile devices.

 What is The Need For MCC? 

If you play games or watch videos for long hours, your phone gets heated up, and the battery drains. Similarly, if the mobile stores all the data, photos, and applications, you need a laptop-sized memory and a table fan to cool the smartphone.

To allow the user to access all the features while maintaining the size and functionality of a smartphone, we need to store the data in a remote server and use it for complex solutions, data storage, and high-functionality tasks. The data is available to the user whenever they want to access it through MCC.

Real-time Example of MCC:
Imagine using Google Maps. When you search for a route from your home to your office, the remote cloud servers receive the request. Google servers process large volumes of data, such as traffic conditions, road closures, distances, and fastest routes. Within nanoseconds, Google Maps gives you directions. Google Cloud servers store all Google apps-related data.

Architecture​ of Mobile Cloud Computing:

The architecture of MCC describes how mobile devices and cloud remote servers work together to deliver services. It consists of three main components:  Device Layer, Communication Networks, and Cloud Infrastructure. 

In between, there are intermediate components such as the cloudlet layer, middleware layer, load balancer, synchroniser, and security layer. Each component performs functions that enable efficient communication and data processing among the 3 main components.

The intermediate layers help in smooth data transmission and improve speed, performance and reliability. They reduce delay by processing simple tasks rather than transmitting everything to the clouds.

Device Layer:

The mobile device is the starting point of the MCC architecture. Devices such as smartphones, tablets, and wearable gadgets act as the interface between the user and the cloud. 

• The process starts when the user opens an app, clicks a button, or uploads a file.
• The mobile app converts this action into a digital request. 
• The device may perform light processing, format data, compress files, and authenticate.
• The system decides whether to process simple tasks using a network provider or send them to the cloud for complex tasks.
• The request is sent wirelessly as data packets suitable for transmission.

Communication Network (Network Layer):

The communication network acts as an interface between mobile devices and the cloud. 

•  The request prepared by the mobile device passes through the network to the cloud servers.
• Technologies such as Wi-Fi, 4G, and 5G enable communication between the mobile device and the cloud.
• The request travels through multiple network nodes, routers, base stations, and ISPs to reach the correct cloud server.
• The network ensures fast data transfer while minimising delays for a smoother experience.
• Encryption and secure protocols such as HTTPS protect data in transit.
•  After processing in the cloud, the results are sent back to the mobile device over the same network.

Cloud Infrastructure (Cloud Layer) :

The cloud infrastructure is the core of MCC architecture. It consists of powerful remote servers and data centres that provide data storage, power, and application services. This layer supports various cloud service models, including IaaS, PaaS, and SaaS.

• This layer supports various cloud service models, including IaaS, PaaS, and SaaS.
• The cloud servers receive the request from the mobile device over the network.
• Servers perform heavy computation such as running applications, processing data, or handling complex tasks.
• The cloud stores large amounts of data in databases and storage systems, accessible at any time.
• The cloud has tons of processors, memory, and storage available; depending on demand, servers share the resources.
• Data is protected through encryption, authentication, and backups to prevent loss.
• After processing, the cloud generates results and sends them back to the mobile device via the network.

Mobile Cloud Computing Challenges: 

The challenges of MCC stem from network dependency, wireless transmission, limited mobile storage, and the risk of server hacking and data leaks. Technology is advancing, and simultaneously, hackers are using it to develop new methods for accessing data.

• A communication network is required for the mobile to communicate with servers. This mobile dependency on the network is a major limitation. Without a network, your phone is just a pen drive. 
•  The time between a user request and the receipt of the response is known as latency. Real-time app data transfer delays due to weather conditions, high-rise buildings obstructing the signal, interference from other signals, or rapid changes in information. High-speed internet is not available in all regions, resulting in slow processing.
•  Data and cloud computing companies protect data with end-to-end security measures, encryption, and protocols. Even then, data is vulnerable to hacking and unauthorised access.
• The maximum amount of data transferred in a given time is the bandwidth. MCC has no fixed bandwidth. It depends on the network availability in that specific area. Bandwidth is affected by fluctuations in signal strength and by too many users accessing at the same time from the same location. 
• Using mobile data (4G/5G) can be expensive for heavy cloud usage. High-speed access leads to high cost.
• A variety of devices, such as Android and iOS phones, low-end & high-end phones, are used to access the apps. Different devices, various screen sizes, operating systems, and configurations create compatibility issues.
• Mobile services will be unavailable due to network failure or cloud server downtime. Nowadays, phones are used continuously, and data is accessed 24 hours a day. This high usage results in latency, bandwidth, and other issues that affect reliability.

Scope of MCC:

The scope of MCC spans across all fields that are digitised and depend on the internet for data, storage, or programming. As long as mobile exists, MCC will continue to evolve.

• MCC is essential for high-performance apps like gaming and video streaming. They need an advanced processor and memory to run smoothly without interruption.
• Hospitals and health care need a remote server to store test reports, information, and patient monitoring data. Doctors can access patient data and suggest treatments remotely. 
• Students can access study materials and use common educational tools from anywhere, 24/7, and institutes can avail automatic backups and easy sharing with thousands of students simultaneously. For delivering video lectures and for effective interactions.
• MCC helps with traffic control by enabling real-time traffic data analysis and updates.
• Reliable, secure online payments and banking activities happen remotely and safely.
• Users can enjoy high-quality content on social media.YouTube is also a cloud service that hosts content from creators worldwide.
• Employees can access company emails, tools and data securely, even from home, improving productivity. 
• Netflix and Spotify use cloud servers to store their data.
• Google Docs and Dropbox allow you to store, edit and access files anytime from anywhere. Remote servers store all the Docs, but not on your mobile.

How to Learn MCC? 

Cloud Computing provides services over the internet. whereas MCC specifically delivers those services to mobile devices, overcoming their size, battery, and memory limitations. To learn MCC effectively, it is important to understand cloud computing concepts. MCC builds upon cloud services to extend functionality to mobile devices.

For easy understanding, we can frame it as : MCC = Cloud Computing+Mobile Basics +Bandwidth & Latency handling +Offloading concepts+Security & Efficiency measures
