CAREER: Capacity and Ubiquity in Multitier Wireless Networks

摘要为了满足用户多样化的通信需求，无线系统必须同时支持广域接入（Ubiquity）和局域性能（Capacity）。多层无线网络代表了实现这些共同目标的自然设计选择。这些网络包含无线电，其覆盖范围按其数量级变化。覆盖范围更大的高层无线电扩展了网络的覆盖范围，而低层无线电的目标是特定位置的性能。本文研究了各种多层网络所支持的容量和普遍性。作为这种系统所提供的效益的一个示范，将利用萨斯奎哈纳县的地形和人口数据来执行衍生结果，并为该地区设计一个多层网络。萨斯奎哈纳县是宾夕法尼亚州北部一个农村和技术贫乏的县。该设计将考虑到该地区极丘陵的传播特征；人口中心的位置；以及这些地点的通信需求，以便更好地满足县的需求（例如，提供令人满意的蜂窝网络覆盖，提供宽带接入，促进远程学习计划等）。总体而言，本研究旨在为频谱高效的多层系统开发一个通用和统一的框架。具体地说，它检查了各种集中式和分散式多层配置的全频谱重用交叉器的情况。在集中式网络中，用户只与接入点通信，接入点控制准入和路由信息。在非集中式系统中，这种责任分布在接入点和用户上，并且可以进行临时连接。关键的挑战在于克服高频谱复用产生的跨层干扰。本研究开发了1)模拟这种干扰的分析方法；2)利用信号处理、无线电资源分配和访问控制技术共同抑制它，并提供所需的普遍性和容量。提交给美国国家科学基金会（NSF）的提案封面单在线使用NSF提案编号日期收到副本数量部门指定的基金代码duns#（数据通用编号系统）文件位置供NSF组织单位考虑（注明最具体的单位，即项目，部门等）项目公告/征集号。/截止日期/如果不是响应计划公告/征集，请输入NSF 03-041雇主识别号码（EIN）或纳税人识别号码（TIN）显示以前的奖励编号。如果这是一个基于成就的更新，这个提案会提交给另一个联邦机构吗？是否如果是，请列出应授予奖项的机构名称的首字母缩略词获奖机构地址，包括9位邮政编码获奖机构代码（如果知道）是获奖机构（检查所有适用的）小型企业少数族裔企业如果这是一个初步建议（见GPG II.C定义）营利性组织女性所有的企业，然后检查演出机构的名称，如果与上述演出机构地址不同，如果不同，包括9位邮编执行机构代码（如知道）提议项目的名称请求金额$提议持续时间（1-60个月）请求开始的月份显示相关的初步提案编号。如适用，请在适当的方框中勾选本建议书中所列的任何项目：开始调查员（GPG I.A）游说活动披露（GPG i.c）专有和特权信息（GPG I.B， II.C.1）。d)历史名胜（GPG ii . c .）给探索者的小额补助。研究（sger） （gpg ii.d）脊椎动物（gpg ii.d .）5) IACUC App. date . human SUBJECTS （GPG II.D.）6)豁免条款或IRB申请日期国际合作活动：涉及的国家/地区（GPG II.C.2）j)高分辨率图形/其他需要精确颜色表示以正确解释的图形（GPG I.E.1）PI/PD部门PI/PD邮政地址spi /PD传真号码姓名（打字）高学历学位年数电话号码电子邮件地址spi /PD namco -PI/PDCO-PI/PDCO-PI/PDCO-PI/ PDCO-PI/PDCO-PI/PDCO-PI/ PDCO-PI/ 20346945 CCR -通信研究nsf 02-111 07/22/03240795445利哈伊大学0032896000利哈伊大学校友大楼27Bethlehem， PA。职业：多层无线网络的容量和无处不在电子工程美国shalinee Kishore PhD 2003 610-758-4517 skishore@lehigh.edu808264444Electronic授权组织代表或个人认证申请人：通过签署并提交本提案，个人申请人或申请机构的授权官员是：（一）就其所知，证明本协议所述内容真实、完整；(2)同意接受遵守NSFaward条款和条件的义务，如果由于此申请而作出裁决。此外，申请人在此提供关于禁止和暂停，无毒工作场所和游说活动（见下文）的证明，如拨款提案指南（GPG）， NSF 03-041所述。在此申请及其证明文件或随后的奖励要求的报告中故意提供虚假信息是一种刑事犯罪（美国法典，标题18，Section 1001）。此外，如果申请机构雇用超过50人，则申请机构的授权官员证明该机构已实施符合《拨款政策手册》第510条规定的书面和强制执行的利益冲突政策；就他/她所知，该利益冲突政策所要求的所有财务披露均已作出；根据机构的利益冲突政策，所有确定的利益冲突将在机构支出任何奖项下的资金之前得到令人满意的管理，减少或消除。不能令人满意地管理、减少或消除的冲突必须向国家科学基金会披露。无药物工作场所证明通过电子签署NSF提案封面，授权组织代表或个人申请人提供资助提案指南附录C中包含的无药物工作场所证明。吊销执照及停职证明（如回答“是”，请说明原因。）该组织或其负责人目前是否被任何联邦部门或机构禁止、暂停、提议禁止、宣布不合格或自愿排除在涉及的交易之外？是否通过电子签署NSF提案封面，授权组织代表或个人申请人提供资助提案指南附录D中包含的取消和暂停证书。关于游说的认证对于授予超过10万美元的联邦合同、赠款或合作协议，以及授予联邦贷款或承诺为美国担保或担保超过15万美元的贷款，都需要此认证。合同、赠款、贷款和合作协议的证明下述签署人尽其所知和相信，保证：(1)下述签署人或其代表没有因影响或试图影响官员或雇员而向任何人支付或将支付联邦拨款

CAREER: Capacity and Ubiquity in Multitier Wireless NetworksAbstractTo meet diverse communication requirements of users, wireless systems mustsimultaneously support wide-area access (ubiquity) and local area performance(capacity). Multitiered wireless networks represent a natural design option that fulfillsthese joint goals. These networks contain radios designed with coverage areas that varyin their order of magnitude. Higher-tier radios, which have larger coverage, extend thenetwork's reach while lower-tier radios target location-specific performance. Thisresearch studies the capacity and ubiquity supported by various multitier networks. As ademonstration of the benefits offered by such systems, topographic and demographic datafor Susquehanna County, a rural and technology-poor county in Northern Pennsylvania,will be used to implement derived results and to devise a multitier network for thatregion. This design will take into consideration the extremely hilly propagationcharacteristics of the area; location of population centers; and communicationrequirements at these locations in order to better serve the needs of the county (e.g.,provide satisfactory cellular coverage, deliver broadband access, promote distancelearning initiatives, etc.).Overall, this research aims to develop a general and unified framework for spectrallyefficient multitier systems. Specifically, it examines the case of full spectral reuse acrosstiers for various centralized and decentralized multitier configurations. In centralizednetworks, users communicate exclusively to access points, which control admission androute information. In non-centralized systems, such responsibilities are distributed overaccess points and users, and ad-hoc connections are possible. The key challenge lies inovercoming cross-tier interference produced by high spectral reuse. This researchdevelops analytical methods that 1) model this interference; and 2) use signal processing,radio resource allocation, and access control techniques to jointly suppress it and deliverdesired ubiquity and capacity.COVER SHEET FOR PROPOSAL TO THE NATIONAL SCIENCE FOUNDATIONFOR NSF USE ONLYNSF PROPOSAL NUMBERDATE RECEIVED NUMBER OF COPIES DIVISION ASSIGNED FUND CODE DUNS# (Data Universal Numbering System) FILE LOCATIONFOR CONSIDERATION BY NSF ORGANIZATION UNIT(S) (Indicate the most specific unit known, i.e. program, division, etc.)PROGRAM ANNOUNCEMENT/SOLICITATION NO./CLOSING DATE/if not in response to a program announcement/solicitation enter NSF 03-041EMPLOYER IDENTIFICATION NUMBER (EIN) ORTAXPAYER IDENTIFICATION NUMBER (TIN)SHOW PREVIOUS AWARD NO.
