I. INTRODUCTION
The fate of the media transmission will be found out from
the results of the investigation. This examination will talk
about the future ways and procedures for limiting the
difficulties in the media transmission part. This exploration
will help in recognizing a few answers for handling half
breed frameworks of remote access organizing including
WLAN and second and third era of Mobile Networks. This
paper will help in stretching out answers for a satellite
frameworks dependent on DVB-S/RCS convention stack
[1] This examination will help in dissecting dangers
associated with the incorporation of satellite frameworks in
earthly remote correspondence systems. This exploration
will incorporate a fundamental investigation of the
utilization of a few earthly guidelines in a satellite setting
of 4G get to. Satellites have been used in various purposes
that brings up new opportunities as well as challenges of
satellite and telecommunication industries.
A. RESEARCH AIM, OBJECTIVES AND
QUESTIONS
The aim of study is to integrate satellite and terrestrial
wireless communication networks. This paper aims at
optimizing routing protocol for broadband hybrid satellite
communication IP network system.
Following are the objectives of the study:
• To analyze architecture of the satellite wireless
networks
• To identify issues in the terrestrial wireless
networks in communication
• To integrate satellite and terrestrial wireless
networks in communications
Following are the research questions:
• What is architecture of satellite wireless
networks?
• What are the issues in terrestrial wireless
networks in communication?
• How to integrate satellite and terrestrial wireless
networks in communications?
II. LITERATURE REVIEW
The main issue is to enhance TCP execution over satellite
systems and a convention called beneficiary window
backpressure convention is proposed to be utilized inside
the satellite systems (RWBP). RWBP has recently
composed clog control, blunder control and cradle
administration plans. Furthermore, it requires less invert
channel data transfer capacity without yielding the forward
channel throughput. RWBP can still keep up great
execution notwithstanding when there is high need activity,
for example, spilling video and sound contending with the
TCP movement in the satellite systems. The second issue is
to examine the exchange of short messages with deferral
limitations in the switch channel [9]. Satellite transaction
has been important in the cases of the telecommunication
industry. The use of terrestrial satellite has been
maintained in different characteristics for developing
different role in the industry. The clarity in the sound has
been improved in the industry. The range of
telecommunication has been increased in maximum range
[6].

As indicated by the preparing capacity, satellites can be
delegated twisted pipe satellites and on-board preparing
(OBP) satellites [4]. Twisted pipe satellites are physical
layer gadgets and they are essentially flag repeaters in the
sky. The signs gotten on the satellite uplink are enhanced
and communicated at an alternate recurrence on the
downlink. Further developed OBP satellites suit baseband
computerized flag handling, uplink data transmission

controller and quick parcel exchanging on board. OBP
satellites are connect layer gadgets and they frame a work
arrange topology instead of a star topology as in the bowed
pipe satellite systems [12]. Satellite and terminal versatility
joined with radio wave blurring because of territory (e.g.
burrows, mountains, foliage) likewise add to the satellite
connection mistakes.

For this situation, the new association is set up with new
AP. WiMAX standard is alluded to IEEE 802.16 and
helping in offering broadband remote access to various
clients and association [13]. This design helps in
interconnecting diverse base stations in both in point to
point mode in work mode. Bluetooth is another specially
appointed standard that aides in exchanging records and
information inside a short range. The engineering is
distributed association between tow gadgets inside
terminals. It is viewed as IEEE 802.15.
III. METHODOLOGY
The initial phase in recognizing the last reconciliation
design for conventions has been finished utilizing basic
investigation of the necessities of the last system. Data
collection has been an important section of the research.
Data has been collected from various online journals,
books, articles and governmental databases. Therefore,
secondary method of data collection method has been used.
Qualitative approach has been used in the research study.
Statistical experimental analysis method has been selected
in the study. A new architecture has been proposed for
designing the satellite communication in the wireless
communication. The testing part of the architecture has
been discussed in the next section.
This research relies upon compromise of satellite
frameworks and terrestrial remote frameworks. The
guideline purpose of research paper has been exploring
hybrid structures for fusing satellites with existing natural
remote correspondences. This research will help in
separating a couple of answers for taking care of creamer
systems of remote access sorting out including WLAN and
second and third time of Mobile Networks. The proposed
outcome has been positive in order to optimize routing
protocol for broadband hybrid satellite communication IP
network system.
B. SIMULATION
The Network Simulator 2 (NS2) package has been designed
in the frame of VINT Project for analyzing behavior of
protocol in the wired network. However, software modules
have been included for extending the analysis of the
wireless and satellite networks. NS-2 is an object oriented
simulator, written in C++, with an OTCL (Object Tool
Command Language) interpreter as a front-end. The
simulator has been supporting a class hierarchy in C++, and
a similar class hierarchy within the OTCL interpreter.
There have been different effects of the DBA algorithm as
shown in figure below and different data has been found in
the system.

Figure 4: NS2 link structure

The above figure describes that at time 20 s the handover
towards the second link happens, with a new throughput of
1 Mbit/s and a propagation delay of 520 ms. However, at
120 s, there is the handover to first link. At 150 s, simulator
ends. TCP Reno has general problems during transition and
has less impact on handover at connection time of 20s. IT
has been worst at 120 s as buffer time is very large.
