1.Introduction
• Wireless mobile communication networks have been
evolved for generations
The generations that are evolved in it are
• 1G Wireless mobile communication
•1G Wireless Communication:
Wireless mobile communication networks have been evolved for
generations. The first generation (1G) wireless mobile communication
network is an analog system which is used for public voice services with
the speed up to
2.4kbps [1].

• 2G Wireless Communication:
• The second generation (2G) uses the digital technology and network
infrastructure.
• In comparison with the first generation, the second generation supports text
messaging [2].
• Its success and the significant growth of demand for online information via
the internet have prompted the development of cellular wireless system with
the
improvements on data connectivity, which is ultimately led to the third
generation
• 3Gsy sWtemisr(e3Gle). ss Communication:
• The 3G system refers to technology standards for the next generation of mobile
communications systems.
• The main goal of standardization efforts of 3G is to create a universal
infrastructure
that is able to support existing and future services.

• 4G Wireless Communication:
• The 4G mobile system is an all IP-based network system. The features of 4G
may
be summarized with one word—integration. The 4G systems are about
seamlessly integrating different technologies and networks to satisfy increasing
user demands.
• 4G technologies combine different existing and future wireless network
technologies (e.g. IPv6, OFDM, MC-CDMA,LAS-CDMA and Network-LMDS)
• The 4G networks integrate one core network with several radio access networks.
A core interface is used for communication with the core network and radio
access networks and a collection of radio interfaces is used for communication
with the radio access networks and mobile users.

Multi Bandwidth Data path design for 5G Wireless Systems

• 5G Wireless mobile
communication:
•The 5G, on the other hands bring us to a perfect real world wireless or so-called
“WWWW: World Wide Wireless Web” . The idea of WWWW, World Wide
Wireless Web, originates from the 4G technologies. The next evolution will be
based on 4G and the completion of this idea results in the formation of a real
wireless world.
• Integrating IPv6 and multi-bandwidth data path for 5G WWWW is a challenging
issue, due to the following factors –
1) the IPv6 assigns IP address on mobile nodes according to its location
information, which is related with location management;
2) multi-bandwidth data path design is based on network resources efficient
utilization, which is related with network resources management.
•This paper is organized as in section 1 presents an introduction and
section 2 discusses the review of literature. The design of multi bandwidth
data path is presented in section 3 and we describe the implementation in
section 4, and finally, section 5 is summarization and conclusions.

The WiFi 802.11 family is designed for local area, which can cover 100 meters.
•Bluetooth provides a wireless Airport (802.11b, 802.11g and 802.11n) solution for
wireless networks, not a replacement for networking.

3.MULTI BANDWIDTH DATA DESIGN
Multi Band Width data design can be categorised into two ways:
 Multi-Bandwidth Data Path Model Design
 Multi-bandwidth Data Path Design
•Multi-Bandwidth Data Path Model Design:
This model is based on overlay area of any two networks. When a mobile node comes
into the overlay area, both of the two networks can supply services for the mobile node
simultaneously. Data request can be sent from any one network, and reply can be
from any other network.
•MULTI-BANDWIDTH DATA PATH DESIGN:
The function of bandwidth management is to install and delete bandwidth
monitor components dynamically when it receives indication messages from
the mobile IP protocol.

2.Multi-Bandwidth Data path Architecture

In the following Multi-Bandwidth Data Path Architecture the following existed contents
that can be explained as follows:
1.Bandwidth Management
2.Bandwidth selection
3.Bandwidth monitor
4.Packets Receiver
1.Bandwidth Management:
•The bandwidth management is located at both ends of the sender
and
the receiver.
•We assume that any two networks are WLAN and CDMA2000. WLAN
is used to cover small area, and CDMA2000 covers wide area. Both
of
them have differences in bandwidth, data rates and cost.
•Therefore, bandwidth management component is needed for
implementing the selection of bandwidth in the Multi-bandwidth data
p•aDthu rainrgch tihteec btuarned.width selection, the bandwidth management will perform the
following two operations:
1.RATE_READY
2.RATE_DEL

2.Bandwidth Selection:
•Bandwidth selection is located at the sender side only. Since
WLAN has integrated into CDMA2000 networks, the message
exchange is
between both networks i.e., from the sender to the receiver.
•The bandwidth selection is also responsible for assigning
bandwidth encoded IPv6 application.
3.Bandwidth Monitor:
•The function of bandwidth monitor is to calculate the proper transmission
rates and monitor packet flows on the corresponding path. The bandwidth
monitor is
located at both the sender and the receiver on each bandwidth path which is
installed by the bandwidth management.
•The data transmission rate is calculated by certain algorithm. From the
theoretical point, a lot of rate control algorithm can be used in this propose
architecture to calculate data rates.
•However, we has selected TCP friendly rate control (TFRC) algorithm [27]
for the bandwidth monitor.

4.Packets Receiver :
Packets receiver is located at the receiver side only. The function of packets receiver is
to buffer and reorder all the packets received from both bandwidth monitor. It is further
to filter out the redundant packets before delivering them to the target application.
4.PERFORMANCE ANALYSIS:
According to the prediction for 4G in [19], the available bandwidth is ranging
from 5Gbps to 25Gbps, which is enough wide for mobile user.
Thus, the performance analysis based on two factors:
1. Buffer Requirement Analysis
2. Numerical Results
1.Buffer requirement Analysis:
According to ITU (International Telecommunication Unit) standards, for a non
real-time internet session, the buffer time, Bt , is defined as the length of time that
the packets are released from the existing route to a new route which is established
and this is calculated as follows

Bt=Rt(CN.MN)
………(1)
•During the course of the simulation, the IPv6 packets were transmitting
from CN to MN, using the any two nodes distances by the packets rate
to calculate the buffer time for the IPv6 packets which is from CN to MN.
Then, the required buffer size is calculated as follows:
Bs=Bt*Pr
Pr=br*Ps
…………..(2)
.…………(3)
From the equation (2)&(3) we get
Bs=Bt*br*Ps

2.NUMERICAL RESULTS:
•The requirements of buffer size in the integration of IPv6 and Multi-bandwidth.
As the number of internet reselection session increased, the buffer size
requirement is increased.
•This is because in formula (4) above, the buffer size is depending on three
factors: buffer time (Bt), bit rate (br ) and the packet size (Ps ).
•The buffer requirements are same whatever with bandwidth reselection or
without bandwidth reselection.
•This is because that there are same numbers of active data sessions applying for
buffer spaces in both cases.

5.CONCLUSION AND FUTURE WORK:
•In this paper, we proposed Multi-bandwidth data path scheme for 5G real wireless
world.
•Data requests will be controlled by PCF (Packets Control Function) in the
CDMA2000
network and data reply will be controlled by PDIF (Packet Data Interworking
Function) in
WLAN.
•Data traffic is routed through PDSN from CDMA2000 network to WLAN network.
•The Multi-bandwidth data path scheme has been defined to do bandwidth
reselection for rerouting so that all network resources can be used efficiently.
•The new Multi-bandwidth data path scheme does not consider issues
such as congestion relief, re-negotiated QoS, or the movement pattern of
the mobile node.
