Effective Dynamic Multilevel Bandwidth Allocation Scheme For Fiwi Networks

In order to provide a network infrastructure to over 600 users on the TaxiPixi network infrastructure, Fiber optic cabling system will be implemented in the LAN design because it is one of the best transmission media options.

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

Speed control for best effort traffic restriction is designed to create the necessary bandwidth. Speed control is also best effort traffic and bandwidth used in an effective way that only real-time traffic not used during any special occasion. The overall speed of the traffic and best effort traffic distribution in real time during each conductive network with a common time, to maximize long overdue, following a real threshold is

The municipal network was developed on a network of optical cores. That has access points on every street light poles and traffic poles. It connected 30 percent of the city by using more than 400 such access points. Only municipal services were delivered using this infrastructure. The aim of this implementation were,

In this smart world there is a rapid growth in using mobile network for requesting many queries, especially videos.Problem is more Base Staion (BS) is required for providing a continuous service, for the user to view videos without getting buffer, or in degrading of video quality. Since more BS are required, all BS has to be active all time, therefore energy requirement is more. It cause more power consumption, also if BS is reduced for save power it leads to poor quality of service(QOS). During peak traffic load during rush hours, wireless access network must be over deployed. It requires lot of BS to be active even when many times slots in a BS are free while providing service. Also, in a low-traffic period, the user will not request any data, but the BS have to be active.

The current network has approximately 3000 end users in which 2500 are students and 500 staff members furthermore we have 240 access points through which any users can connect to the

The need for speed of a wireless network is always insatiable. The first standard that appeared fifteen years ago provided speeds of 1 Mbps and 2 Mbps to be used in office buildings where mobility was not a requirement [5].

The application of optical fiber is increasing rapidly in telecommunication and CATV subscriber network and the mass deployment of fiber in the loop (FITL) has begun in Germany. The promising cost effective topology has been generally considered and picked is the passive optical network (PON). The most aggressive movement in Germany happened during early 1990, long-rang plans were made for wide-scale

Information technologies provide opportunities for improved and more flexible working methods in a small business office. In particular, the provision of wireless broadband network infrastructure is an important element in business premise. It supports applications that require the exchange of complex large documents. It is convenient for integration of many business-to-customer and business-to-business services.

Wide spread acceptance of wireless technologies has given rise to increase in demand for bandwidth .cognitive radio was developed as a promising technique to overcome the scarcity of spectrum resources in wireless communication. The term cognitive radio is defined as an intelligent radio that can be programmed and configured dynamically. Particular portion of the spectrum can be used only by a specific user of communication systems i.e. licensed user (or) primary user (PU). The secondary user is cognitive user (CR). There are two main paradigms to implement CR in practical, namely interweave and underlay techniques. The main motive of

Poisson distribution is also known as a discrete of probability distribution which often describes as the arrival rate in queuing theory. The last major of characteristics is waiting line. For characteristic of waiting lines is a queuing discipline when the first customers in line receive the first service and known as first-in first-out (FIFO) rule. The third of characteristics of queuing theory which is service characteristics that have some major such as basic queuing system designs which classified in terms of channels number and phases number. In basic queuing there have single-channel queuing system which mean a service system with one line and one server, multiple-channel queuing systemwhich mean a system of service that have one waiting line unfortunately have several servers, single-phase system which is the customer receives service from only one station and then exits the system and multiphase system which is the customer receives service from some stations before exiting the system. In service characteristics also have service time distribution which is the arrival patterns can be either constant or random. According to (Mital

The OSI model defines internetworking in terms of a vertical stack of seven layers. The upper

ATM (Asynchronous Transfer Mode) has been advocated as an important technology for all types of services and networks. Most people believe that ATM will be the standard for the future B-ISDN (Broadband Integrated Services Digital Network). From the service point of view, ATM combines both the data and multimedia information into the wired networks while scales well from backbones to the customer premises networks. To ensure the success of ATM, lots of the design issues have been standardized by ATM Forum. Wireless personal communication networks (PCN) has been growing very fast in the last decade. Nowadays, laptop, cellular phone, and pagers are very popular. Many systems have been developed to provide different services, such as, Personal Communications Service (PCS), Portable Telephone Systems, and Satellite Communications System. Usually, these services do not guarantee QoS (Quality of Services) so they are not suitable for the fast growing multimedia applications. Due to the success of ATM on wired networks, wireless ATM (WATM) is a direct t result of the ATM "everywhere" movement. WATM can be viewed as a solution for next-generation personal communication networks, or a wireless extension of the B-ISDN networks, which will support integrated data transmission (data, voice and video) with guaranteed QoS. WATM architecture and protocols are already being well discussed. The ATM Forum are currently involved in defining the baseline

WiMAX (Worldwide Interoperability for Microwave Access) is present as a solution to the limitations of access at Wi-Fi planned for adoption in the space. The use of OFDM technology is able to provide data service to 70 Mbps in a radius of 50 km. Radius to make WiMAX broadband telecommunications network as technology replaces fixedline. Compared to the fixedline network WiMAX installation fees are much cheaper.

Several dynamic bandwidth allocation techniques have been proposed in the research community adopted on different FiWi networks’ architectures, which combine different technologies of optical and wireless networks.
