Description

It is important to develop high-capacity mobile broadband networks for exponential growth on mobile users. In the near future a collection of data communication networks (the Internet) is going to provide a variety of services through multiple service classes where each service class will provide a different performance in terms of response time. The hybrid wireless-optical broadband-access network (WOBAN) is a promising architecture for future access networks. Recently, the wireless part of WOBAN has been gaining increasing attention, and early versions are being deployed as municipal access solutions to eliminate the wired drop to every wireless router at customer premises. This architecture saves on network deployment cost because the fiber need not penetrate each end-user, and it extends the reach of emerging optical-access solutions, such as passive optical networks. These service classes will be designed to provide appropriate levels of service to user applications. In order to achieve this we integrate PON and 4G. Integration of PON and 4G technologies in the form of wireless-optical broadband access net-works, offers advantages, such as extension of networks in rural areas, support for mobile broadband services, and quick deployment of broadband networks. Results indicate that our proposed class-based power saving scheme reduces power consumption by up to 80 % , and maintains the QoS within the requirements of the service level agreement.
