国家科学基金会NETS-网络技术与系统研究CISE/CNSABSTRACT提案编号：0435341主要研究员：刘庆冲机构：奥克兰大学提案编号：0435155主要研究员：乔春明机构：纽约州立大学布法罗分校提案标题：合作研究：NetTS-NR：超宽带光无线通信网络这个合作研究项目承担了光无线通信（OWC）的多学科方法网络，并侧重于现有光纤骨干网与许多家庭和小型办公楼之间的第一/最后一英里。 该项目旨在开发新的OWC网络和通信理论和技术，包括克服闪烁的物理层（光强变化），以及链路层和网络层在设计最优拓扑、生存路由时考虑OWC的独特能力和约束条件，以及创新的动态重新配置算法，以减轻重雾或浓雾的负面影响，并降低每条链路的成本。 由于该项目的努力，将建立一个OWC环形网络，运行多媒体应用程序。该项目的成功预计将提供负担得起的超宽带第一/最后一英里接入，使新的多媒体应用程序能够交付给住宅和小型办公楼，并作为基于射频的异构技术集成的垫脚石（例如，无线局域网、WLAN和蜂窝网络）和光纤。 Admela Jukan博士，CISE/CNSAug 5，2004.

National Science FoundationNETS - Research in Network Technologies and Systems CISE/CNSABSTRACTProposal Number: 0435341Principal Investigator: Liu, QingchongInstitution: Oakland UniversityProposal Number: 0435155Principal Investigator: Chunming QiaoInstitution: SUNY at BuffaloProposal Title: Collaborative Research: NeTS-NR: Ultra-Broadband Optical Wireless Communication NetworksThis collaborative research project undertakes a multidisciplinary approach to optical wireless communications (OWC) networks and focuses on the first/last mile between the existing fiber-optic backbone and many homes and small of-fice buildings. The project aims at developing novel OWC networking and communications theory and techniques including those at the physical layer that overcome the scintillation (variation in light intensity) caused by the at-mospheric turbulence in OWC networks through sub-carrier modulation and coding, and those at the link and network layers that take into consideration the unique capabilities and constraints of OWC when designing optimal topol-ogy, survivable routing, and innovative dynamic reconfiguration algorithms to mitigate the negative effects of heavy or dense fog, as well as reduce the per link cost. As a result of the project effort, an OWC ring network will be built, running multimedia applications. The success of the project is expected to pro-vide an affordable ultra-broadband first/last mile access, enable new multime-dia applications to be delivered to residential homes and small office buildings, and serve as a stepping stone to the integration of heterogeneous technologies based on radio frequency (e.g., Wireless Local Area Networks, WLAN, and cellu-lar networks) and fibers.
