Integration of next generation wireless technologies i.e., WiMAX (Worldwide Interoperability for Microwave Access)
and or LTE (Long Term Evolution) with EPON is a brilliant concept that gives users the best of two worlds, wireless
and wired. WiMAX gives users the convenience of mobility while integration with EPON gives theoretically unlimited
bandwidth of fiber optic cable in backhaul. This paper investigates WiMAX and EPON technologies. At the end
different scenarios of integration of EPON with WiMAX are discussed and optimal QOS mapping scheme is proposed
for the integration of EPON and WiMAX.
Mobile networks and services have gone further than voice-only communication services and are rapidly developing
towards data-centric services. Emerging mobile data services are expected to see the same explosive growth in demand
that Internet and wireless voice services have seen in recent years. To support such a rapid increase in traffic, active
users, and advanced multimedia services implied by this growth rate along with the diverse quality of service (QoS) and
rate requirements set by these services, mobile operator need to rapidly transition to a simple and cost-effective, flat, all
IP-network. This has accelerated the development and deployment of new wireless broadband access technologies
including fourth-generation (4G) mobile WiMAX and cellular Long-Term Evolution (LTE). Mobile WiMAX and LTE
are two different (but not necessarily competing) technologies that will eventually be used to achieve data speeds of up
to 100 Mbps. Speeds that are fast enough to potentially replace wired broadband connections with wireless. This paper
introduces both of these next generation technologies and then compares them in the end.
Recently, there has been increased interest in the use of optical networks for disaster recovery of large computer systems by extending storage area networks (SANs) over hundreds of kilometers or more. These optical datacom networks, which incorporate wavelength division multiplexing (WDM), have several unique requirements. The purpose of this work has been to develop computer simulation tools for optical datacom networks. The models are capable of automatically designing a WDM network configuration based on minimal input; validating the design against any protocol-specific requirements; suggesting alternative configurations; and optimizing the design based on metrics including performance of the network (efficient use of bandwidth to support the attached computing devices), reliability (searching the proposed topology for single points of failure), scalability (based on user input of potential future upgrade paths), and cost of the associated networking equipment. The model incorporates typical computer performance data, which allows the prediction of system performance before the network is implemented. We present simulation results for a variety of MAN topologies, using currently available WDM networking equipment. These results have been validated by comparison with an enterprise optical networking testbed constructed for storage area networks.
