Abstract -
A multimedia application is used for many fields such as communication, entertainment, and
electronic devices and with the help of multimedia applications, people can use anytime and
everywhere for communication, send information. The multimedia application provides various
challenges and opportunities for the development and research for the support for this application
over technologies of wireless networks. A short term of multimedia application is that to focus
on the design of quality of service over specific technology and long term of application of
multimedia is that to customize various multimedia services over a mixture of accessing
technologies.

Wireless Network –
Nowadays many multimedia devices are connected with wireless networks. Multimedia is a
device that is represented by the presentation of integrative and integrated graphics, video, audio,
gaming, sports, TV broadcasting and text for communication with other people and other
sources. Identifying a new application of wireless multimedia and also for building up a new
advanced algorithm and system are generated by these trends to maintain this wireless
multimedia application. Many clients and users are connected to the multimedia content which is
increasingly and also it is accessed by clients and users from anywhere with various channels of
communication like wireless networks and the internet. Many technologies are used in a wireless
network in which wireless networks are not connected with the cable of any type. Wireless
technologies allow communicating with each other without using any wires and cables and with
the help of wireless technologies many people and organizations can talk to each other over long
distances. There are three types of networks is used in wireless networks.
1. LAN (local area network)
2. WAN (wide area network)
3. PAN (personal area network)
Local area network is used anywhere in a building where a single room and also a whole campus
of building are included. Local area networks use waves of radio. A wide area network is used in
one mobile phone to another mobile phone in which it is accessed by one signal to another signal
from anywhere. A personal area network is a short-range of network such as Bluetooth. It is used
in short distance approx 20-30 feet (Xiong, 2019).

Multimedia Devices:
Many multiple devices are included over a wireless network which is used to send the
information and communication with other users who lives a very long distance. Many devices
are included with communication processes like modem of computer, Wi-Fi, Bluetooth,
Smartphone, many network cards, etc. A telephone is a communication device which may be
wireless or wire but nowadays wireless telephone is used to talk.
Bluetooth – Bluetooth is a multimedia device that is included in the communication process over
a wireless network. Bluetooth is a local area network that is used in short distance location and is
connected between two devices like computer to mobile phone or phone to phone or computer to
computer. With the help of Bluetooth people can send videos, audios, pictures and many
information files in the format of pdf or docs.
Wi-Fi – It is also a multimedia device over a wireless network and it is a wide area network. Wi-
Fi is used for many areas like home, business, public places, and also used for personal purposes.
To connect Wi-Fi with a computer and phone, Wi-Fi adaptor is used which is included in
wireless network. In this device, an AP (access point) connects with the network and any kind of
communication has an access point. Multiple access point is connected each other to handle the
huge amount of users. Nowadays Wi-Fi is used free everywhere such as at Airports, Railway
stations, public places, many big organizations, etc (Collart, 2014).
Computer Modem – Modem of Computer is the best example of communication which is used
for receiving and sending singles that allow to computer to communicate with another computer
with the help of the telephone. A modem is a type of hardware device which connects with the
router or many computers. There are two types of modem is used for communication purpose
that is cable modem and DSL modem. A cable of modem is used contact with a service provider
of internet and with the help of landline and it exchanges a signal of analog to a signal of digital.
A DSL modem is also used to contact with provider service of internet and Motorola is an
example of DSL modem.
Smartphone – In modern life, Smartphone is a very useful and important device for
communication purpose that is also wireless device. Nowadays touch screen Smartphones are
used to allow people to communicate each other. Many functions are used in smartphones for
people to entrainment purposes like games, many socials apps, and business use programs and
also many communication applications are available.
Network cards – for communicating, NIC (network interface card) is used as a network adapter
and Ethernet card. The network interface card is also included in wireless network in which
interface card of network is an expansion card of a computer that is connected over the wireless
network. In the interface of internet cards, two networks used which are internet network and
home network (Chang, 2013).

Many issues obtain of wireless multimedia application –
1. Wireless multimedia application support high quality or level of a video stream for
enhancing the rate of information for Bluetooth over wireless channels. This stream
depends on the type of important content at the level of a video frame to diminish the
impact of frequency of radio, noise, and interference and also the type of content at video
frame quality. It produces because the bit rate of the information is decreased. To achieve
the best and improve video quality over the bit rate is done via imbalanced protection in
streaming of Bluetooth. This stream also defines a radio type frame quality and sizes
camera pans, zooms, etc.
2. Wireless local area network (WLAN) is not appropriate for traffic voice and it is
producing very fast and giving a cost for communications of voice. Wireless local area
network does not support the bandwidth efficiency and the number of calls which support
the bandwidth figure. To increase the capacity to call these schemes to use multicasting
and multiplexing.
3. The wireless network also proposes a scheme of mobility that represents the process of
mobile IPv6 and SIP (session initiation protocol) mobility for a real-time environment.
The mobility scheme is used over wireless networks to reduce the session initiation
protocol and also redundancies of system, various operations of IPv6.
4. In this, a dimensioning method is proposed for video application in wireless networks.
This method provides a simple and latest dimension model for video of conversational
over the wireless network.
5. The issue of multimedia communication over the wireless network is that it supports
multiple coding of description in a distributed framework. For this problem, first of all,
people should compare two or three-band motion and multiple descriptions coding of
video which is based on various time splitting models.
6. The last issue of the multimedia application over a wireless local area network is that the
scheduling of packets of various video frames that are transmitted (Li, 2017).

The architecture of multimedia over Wireless Network –
Multimedia has a very large amount of technologies and it is integrated with various
architectures that are communicated in a real-time environment.
Application
Multimedia extension GUI (Graphic user interface)
Driver support of
multimedia
Software driver Operating system
System Hardware Add on multimedia peripherals and devices
Architecture of multimedia
In this architecture of Multimedia network wireless network, many application is used as an
extension of multimedia and graphic user design. Many software drivers are used like scanners,
sound apparatus, and video cameras to allocate the interface from a multimedia communication
to the device. Many graphics user interfaces such as GGA, XGA, and MCA are used to increase
requirements for top resolution. To understand the architecture of multimedia, the network
architecture is used in which a very huge amount of message, video, and images are transmitted.
A term ATM (asynchronous transfer mode) technology is used to transfer over WAN (wide area
network) and LAN (local area network) (brainkart.com, 2019).
A protocol of Multimedia –

To understand the protocol of multimedia transport is that to communicate multiple signals of
multimedia from one starting point to another ending point. These starting and ending points are
attached to each other by a network of communication that is employed by particular protocols.
Normally these signals are instructed to decrease the rate of bit. The protocol of transmission of
multimedia is dependable for sending streams of encoded one location to another location over
the wireless network for delivering and packaging the streams. After that these streams of
encoded multimedia are responsible for producing and reconstructing from the delivered streams
and packets and it is used to store for additional use. The protocol of multimedia is based on
packet over the protocol of wireless networks and it is used to exchange the information over the
wireless network. The protocol of multimedia application is normally used for User Datagram
Protocol which is depended on the transmission of real-time multimedia. User datagram protocol
does not provide the guarantee of arriving the packets over network but it is a very high-level
application of protocol which provides the security of sending the information.
