国家科学基金NETS-网络技术与系统研究CEISE/CNSABSTRACT论文编号：0435341主要研究员：刘，青冲学院：奥克兰大学论文编号：0435155主要研究员：春明乔所：水牛城州立大学论文题目：合作研究：NETS-NR：超宽带无线光通信网络这个合作研究项目对无线光通信(OWC)网络进行多学科研究，重点关注现有光纤主干与许多家庭和小型建筑物之间的第一/最后一英里。该项目旨在开发新的OWC组网和通信理论和技术，包括物理层的理论和技术，通过副载波调制和编码克服OWC网络中大气湍流引起的闪烁(光强变化)，以及链路和网络层的理论和技术，在设计最佳拓扑结构、生存路由和创新的动态重构算法时考虑OWC的独特能力和限制，以缓解大雾或浓雾的负面影响，并降低每条链路的成本。作为该项目努力的结果，将建立一个运行多媒体应用的OWC环形网络。该项目的成功有望提供负担得起的超宽带第一/最后一英里接入，使新的多媒体应用能够交付到住宅和小型写字楼，并成为整合基于无线电频率(如无线局域网、无线局域网和蜂窝网络)和光纤的各种技术的垫脚石。Admela Jukan博士，项目主任，CEISE/CNS2004年8月5日。

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.
