Architecture of Mobile Computing - (BCA / B.Tech)

Architecture of Mobile Computing in Hindi

The wireless architecture of mobile computing refers to the infrastructure that enables mobile devices to exchange data and connect to networks without any physical connection. The wireless architecture is a set of mobile networks, devices, protocols, and technologies
that ensures users can access the internet, data services, and applications on the go. There are various wireless architectures in mobile computing, based on different technologies and networks.
These architectures are used to connect mobile devices to the internet and other network resources.

Wireless architecture is the foundation of mobile computing, providing connectivity to devices using various networking technologies. It includes different types of architectures such as infrastructure-based networks, ad-hoc networks, and hybrid networks.
These networks are used for various services, applications, and data transmission. Efforts are being made to solve the challenges of wireless networks in mobile computing through new technologies, such as 5G networks and better encryption methods, so that users can have a
more secure and efficient experience.

Main Component of Wireless Architecture in Hindi | Key Components of Wireless Architecture:

Mobile Devices: In mobile computing, the devices used by the user are smartphones, tablets, laptops, etc. These devices have the necessary hardware and software for wireless connectivity, such as Wi-Fi, Bluetooth, GPS, and cellular networks.

Wireless Networks: This is the group of networks through which mobile devices send and receive data wirelessly. This includes Wi-Fi, Bluetooth, cellular networks (2G, 3G, 4G, 5G), satellite networks, etc. These networks use various types of data transmission protocols and technologies.

Base Station: The base station is the equipment that acts as a bridge between the mobile device and the main network. In cellular networks, base stations are cell towers, while in Wi-Fi networks, they are access points. The base station receives signals from the mobile device and forwards them to the main network.

Mobile Switching Center (MSC): This is an important component in a cellular network, responsible for connecting various base stations and other network components. The MSC manages voice calls, SMS, and data transmission between mobile devices. In addition, the MSC also ensures that the connection continues seamlessly when a mobile device moves from one location to another.

Gateway: A gateway is used to connect a wireless network to the internet or other external networks. It helps to bring together different types of network protocols, making data exchange easier.

Data Center and Servers: In mobile computing, data centers and servers are the places from which mobile devices access various applications, services, and data. When a mobile device requests data via the internet or an application, this request is sent to the data center or server.

Types of Wireless Network Architecture in Hindi | Types of Wireless Network Architecture:

There are different types of wireless networks in mobile computing that are designed according to different communication needs and user demands:

1. Infrastructure-Based Network

In this type of network, mobile devices work with a centralized network infrastructure. This means that data exchange between mobile devices happens through a central point (like a base station or Wi-Fi access point). This architecture is seen in cellular, Wi-Fi, and WiMAX networks.

Cellular Networks:

This is the most widely used network architecture, which has evolved as 2G, 3G, 4G, and 5G networks. This network can cover large geographical areas and serve many users simultaneously.
Cellular networks include components like base stations and mobile switching centers, which manage communication.
The 5G network is the most modern technology, which provides high speed, low latency, and more reliability.
It is used not only for mobile internet but also for IoT (Internet of Things), smart cities, and autonomous vehicles.

Wi-Fi (Wireless Fidelity):

This is a local area network (LAN), which is commonly used in homes, offices, and public places. Wi-Fi access points are used to connect mobile devices to each other and to the internet. This network wirelessly distributes the services provided by the Internet Service Provider (ISP).

2. Ad-Hoc Network

Ad-hoc networks are networks where mobile devices connect directly to each other, without any centralized infrastructure. There is no base station or access point. This network can be created temporarily and is useful when there is no infrastructure, such as in emergency services or military operations.

Mobile Ad-hoc Network (MANET): This is a type of ad-hoc network in which mobile devices form a dynamic, wireless network among themselves. Here, each device acts as a router and helps in forwarding data to other devices. This network is self-healing, meaning if a device's connection is broken, it automatically finds a new path.

3. Hybrid Network

A hybrid network is a mix of both infrastructure and ad-hoc networks. In this, some devices are connected through a central network infrastructure, while other devices can connect directly to each other. This network provides more flexibility and can be used in various situations.

4. Satellite Network

Satellite networks are used in areas where traditional network infrastructure is not available, such as remote areas, oceans, or mountains. Mobile devices connect to the internet and other network services via satellite. This network can be slow and may have higher latency, but it is extremely useful for areas where other networks are not available.

Challenges of Wireless Networks in Mobile Computing in Hindi | Challenges of Wireless Networks in Mobile Computing:

Security: Security is a major concern in wireless networks because data transmission occurs through the air, which can make it vulnerable to various types of attacks. Data needs to be encrypted and authenticated to ensure that only authorized users can access it.

Bandwidth Limitations: Mobile networks have bandwidth limitations, especially when many users are using data on the same network simultaneously. This can affect the speed and performance of the network.

Latency: Latency is another problem in mobile computing, especially when the distance between the device and the network is large. New technologies like 5G are working to solve this problem.

Power Consumption: Mobile devices require more energy to stay continuously connected to the internet, which can drain the battery quickly. Energy efficiency is an important factor in wireless architecture.

Connectivity and Coverage: Mobile network coverage can sometimes be limited, especially in rural or remote areas. In addition, the signal can be weak due to buildings or geographical obstacles, which can affect connectivity.
