Book Synopsis Efficient Routing and Resource Sharing Mechanisms for Hybrid Optical-wireless Access Networks by : Yousef Dashti
Download or read book Efficient Routing and Resource Sharing Mechanisms for Hybrid Optical-wireless Access Networks written by Yousef Dashti and published by . This book was released on 2016 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of passive optical networks (PONs) and wireless mesh networks (WMNs) into Fiber-Wireless (FiWi) networks has recently emerged as a promising strategy forproviding flexible network services at relative high transmission rates. This work investigates the effectiveness of localized routing that prioritizes transmissions over the local gateway to the optical network and avoids wireless packet transmissions in radio zones that do not contain the packet source or destination. Existing routing schemes for FiWi networks consider mainly hop-count and delay metrics over a flat WMN node topology and do not specifically prioritize the local network structure. The combination of clustered and localized routing (CluLoR) performs better in terms of throughput-delay compared to routing schemes that are based on minimum hop-count which do not consider traffic localization. Subsequently, this work also investigates the packet delays when relatively low-rate traffic that has traversed a wireless network is mixed with conventional high-rate PON-only traffic. A range of different FiWi network architectures with different dynamic bandwidth allocation (DBA) mechanisms is considered. The grouping of the optical network units (ONUs) in the double-phase polling (DPP) DBA mechanism in long-range (order of 100~Km) FiWi networks is closely examined, and a novel grouping by cycle length (GCL) strategy that achieves favorable packet delay performance is introduced. At the end, this work proposes a novel backhaul network architecture based on a Smart Gateway (Sm-GW) between the small cell base stations (e.g., LTE eNBs) and the conventional backhaul gateways, e.g., LTE Servicing/Packet Gateway (S/P-GW). The Sm-GW accommodates flexible number of small cells while reducing the infrastructure requirements at the S-GW of LTE backhaul. In contrast to existing methods, the proposed Sm-GW incorporates the scheduling mechanisms to achieve the network fairness while sharing the resources among all the connected small cells base stations.

Book Synopsis Optical Fiber Telecommunications VIB by : Vincent W.S. Chan
Download or read book Optical Fiber Telecommunications VIB written by Vincent W.S. Chan and published by Elsevier Inc. Chapters. This book was released on 2013-05-11 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Present-day networks are being challenged by dramatic increases in data rate demands of emerging applications. New network architectures for streaming/routing large “elephant” transactions will be needed for cost and power efficiencies. This chapter examines a number of possible optical network transport mechanisms: optical packet switching, burst switching, and flow switching and describes the necessary physical layer, routing, and transport layers architectures for these transport mechanisms. Performance comparisons are made based on capacity utilization, scalability, costs, and power consumption. A global-reach network architecture, incorporating optical flow switching, will provide significant lower cost and power consumption for large transactions. This transport mechanism will necessitate physical, media access control, routing, and transport layers and control plane architecture changes over the current Internet architecture and must co-exist with traditional TCP/IP electronic packet switching transport in the same optical network. Scalability in network management and control and session scheduling is identified as the most important driver in the architecture construct. The physical architecture coupled with a matched media access control protocol can help slow down the control plane and still can operate the network with highly dynamic sessions and at high efficiency which is critical for low cost and low power operations. For intra-data center networks when the network bandwidth is not as challenged as a wide area network some form of burst switching can be advantageous if fast light-weight protocols are needed albeit the network must be used at light occupancy for low collision probabilities.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cost effective, robust, and high capacity access network necessitated to meet the mounting customer demands for bandwidth-desirous services. A remarkable evolution of access networks is observed both in wired and wireless, predominantly driven by ever-changing bandwidth requirements. A wireless connection releases the end user from the restrictions of a physical link to a network that results in mobility, flexibleness, and ease of use. Whereas, optical networks offer immense amount of bandwidth that appease the most bandwidth voracious customers compared to bandwidth limited wireless networks. The integration of wired and wireless domains in the access landscape that presents a technical analysis of optical architectures suitable to support radio over fiber (RoF) is the objective of this chapter. Investigate the main trends that drive the merger of fiber and wireless technologies in access networks. Moreover, study the primary terms and the particular transmission features of integrated fiber-radio links to form a well-defined classification of hybrid systems and techniques. This work also recognizes the major problems for realization of RoF systems and examines the limitation, advantages, and diversity of integrated RoF-PON technology.
