1.Introduction • Wireless mobile communication networks have been evolved for generations The generations that are evolved in it are • 1G Wireless mobile communication • 2G Wireless mobile communication • 3G Wireless mobile communication • 4G Wireless mobile communication • 5G Wireless mobile communication •1G Wireless Comm Wirele u ss ni mo cati bile co on mmu : nication 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 .
• 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 . • 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 • 3G Wireless Communication: systems(3G). • 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.
• 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.
2.LITERATURE REVIEW •The 4G mobile wireless network is a research area for the next generation wireless systems which can be supported by Bluetooth, WiFi802.11 family, WiMax 802.16 family, cellular and satellite networks. •The Bluetooth is designed for personal area, which can cover 10 meters. 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. •On a technical level, Bluetooth is an open specification for a cutting-edge technology that enables short-range wireless connections between desktop and laptop computers and a host of other peripheral devices- on a globally available frequency band (2.4GHz) for worldwide compatibility. •Many countries have carried out projects for the development of 4G systems. The first project was undertaken by the Defense Advanced Research Projects Agency (DARPA), which is the same organization that developed the wired internet.

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 da • t Da u pa rin th g t archi he b t a e n ct d u wi re dt.h 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 •The data transmission rate is calculated by certain algorithm. From the installed by the bandwidth management. 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  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 , 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
•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 …………..(2) Pr=br*Ps .…………(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 W•O In t R hi K s : 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 •Data traffic is routed through PDSN from CDMA2000 network to WLAN 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.
