 Mobile Computing

Mobile computing is one of the rearmost and evolving technologies. It allows data transmission in the form of voice, image, and video through Internet-enabled or wireless-enabled devices without physical connection, such as computers, IoT devices, etc.

Mobile computing components

The main vertical areas of components involved in mobile computing or mobile cloud computing technology are:

  • Hardware components
  • Software components
  • Communication layer
  • Hardware components
There are different types of hardware components, such as device components or mobile devices that provide mobility services. They can be divided into different market segments, such as smartphones, portable laptops, IoT devices, tablets, etc.

What is the role of hardware components:

These hardware devices have a tiny component called a receiver that can sense, receive and send data signals. It is configured to operate in full-duplex mode, that is, to send and receive signals at the same point in time.

The receiver operates on an existing established wireless network.

Software components

  • Mobile components are software applications that run on mobile hardware components. It's the operating system of the device.
  • This element ensures portability and mobility, and runs on wireless dispatches, and ensures that the computing is distributed in a position, rather than attached to any single physical position.
  • Mobile communication layer:
  • The communication layer represents the underlying infrastructure to ensure seamless and reliable communication. This includes factors such as protocols, services, bandwidth, and portals needed to promote and support. This layer is based on radio waves. The signal travels through the air and communicates with the receiver through software components.
  • The data format is also defined at this layer to ensure conflict-free communication between existing systems that provide the same service.


Mobile Computing-Classification

Mobile computing is widely distributed in various devices that support mobile computing. As we have seen in the history of mobile computing, it is not limited to computers or mobile phones

We can divide these mobile computing devices into the following categories:

Personal Digital Assistant (PDA)

The personal digital assistant, or PDA, is an extension or module of the PC, not a substitute, and is mainly used as an electronic manager. Such devices can share data with computer systems through a process called synchronization.

During this process, both devices will access and communicate with each other to check for any updates in a single device using a Bluetooth or infrared connection.

Using a PDA device, druggies can use an Internet connection to pierce audio clips, videotape clips, update office documents, and further services.

Smartphone

A smartphone is a combination of a PDA and a mobile phone with a camera and other functions (such as executing multiple programs at the same time).

The main mobile operating systems (OS) used are Google’s Android, Apple IOS, Nokia Symbion, RIM’s BlackBerry OS, etc.

Tablet and iPad

This device is larger than a mobile phone or PDA, and it also integrates a touch screen and can be operated by touch-sensitive actions on the network. E.g. iPad, Galaxy Tabs, Blackberry Playbooks, etc.

They provide the same functions as portable computers, support mobile computing in a much superior way, and have the huge processing power.

Reuse in mobile computing

Multiplexing is a process of transmitting multiple simultaneous digital or analog signals through a single data link channel.

It can be further divided into four types. these are:

  • A. Space division multiplexing or SDM
  • Time-division multiplexing or TDM
  • Frequency division multiplexing or FDM
  • Code Division Multiplexing or CDM
  • Multiplexing: Frequency Division Multiplexing (FDM):
  • In frequency division multiplexing, the frequency spectrum is divided into smaller frequency bands. Through FDM, many frequency bands can work at the same time without any time limit.
  • Advantages of FDM
  • This process applies to analog signals and digital signals.
  • Simultaneous size of signal transmission function.
  • Disadvantages of FDM
  • The possibility of bandwidth waste is high and flexibility is low.
  • Multiplexing: Time Division Multiplexing (TDM)
  • The time-division method uses the entire frequency spectrum over some time.

Advantages of TDM

  • Dedicated users at a specific time.
  • Flexible and less complex architecture.
For example, integrated services for digital Internet phone services.

Multiplexing: Code Division Multiplexing (CDM)

In CDM technology, a unique code is reserved for each channel so that each of these channels can use the same frequency spectrum at the same time.

Advantages of CDM

Efficient.
Disadvantages of CDM

The data transfer rate is small.
E.g.: Mobile phone spectrum technology (2G, 3G, etc.).

Multiplexing: Space Division Multiplexing (SDM)

  • It can be considered that the empty segment has both FDM and TDM attributes. In SDM, a specific channel will be used for a specific frequency band within a specific period.
  • Advantages of SDM
  • The highest data transmission rate and the best frequency and time zone usage.
  • Disadvantages of SDM

High reasoning loss.
For example, Global Mobile Services or GSM technology.

Mobile cloud computing

MCC or mobile pall computing uses pall computing to deliver and integrate operations to mobile bias.

Using this mobile cloud computing technology, you can use the speed and flexibility as well as a suite of developer tools to remotely deploy mobile applications.

Mobile cloud applications can be built or updated, and cloud services can be used to quickly and efficiently implement the function of adding new functions to existing applications.
These mobile operations can be delivered to numerous different biases with different operating systems, calculating tasks, and data storehouse mechanisms.

In this way, these applications require fewer device resources because they are cloud-supported architectures, and because the data is backed up and stored in the cloud, reliability is also improved, thereby providing Higher security and robustness.

Advantages of mobile cloud computing:

Based on this built mobile applications cloud architecture has the following advantages:

  • Data storage capacity and processing capabilities have been enhanced.
  • Extend battery life
  • Due to the "stored in the cloud and accessible from anywhere" method, better data synchronization can be achieved.
  • Due to the secure cloud infrastructure and replicas, reliability, scalability, and security are improved.
