Populating our world with networks of sensors requires fundamental understanding of tech-niques for connecting and managing sensor nodes with a communication network in scalableand resource-e .cient ways.The proposed research involves a comprehensive program of sensornetwork architecture,design,evaluation,and implementation that integrates research expertisein the areas of wireless networking and multiuser communications and provides numerous op-portunities for enhancing student research and education in the area of sensor networks,at bothundergraduate and graduate levels.The dominant trend in sensor network practice is to consider a dense collection of tiny sensornodes with limited computation and communication capabilities,all connected via a .at,orad hoc,wireless network.Yet theoretical studies in multiuser communications suggest thatsubstantially improved performance can be obtained through sophisticated coordination amongnodes,requiring more versatile radios,hierarchy,and perhaps even sparse wired connectivity.Thus,the objectives of the proposed research are to:1)identify network architectures thatpermit the implementation of sophisticated transmission schemes that have been theoreticallystudied,2)analyze such schemes in the context of sensor networks and design new ones adoptinga cross-layer approach and 3)implement these schemes and verify their behavior on a realtestbed.The intellectual merit of the project lies in the improved understanding of an importantemerging class of wireless networks,and in the attempt to unite theory and practice.Clos-ing the widening gap between theoretically proposed strategies and practically implementedones is crucial to understanding and improving the performance and lifetime of these resource-constrained networks.Through a rigorous analytic approach,contributions to the emerging areaof network information theory are expected,leading to substantial advances in energy-e .cientand delay-constrained protocol design.The broader impact is manifested in part through an e .ort to integrate teaching and research.Experimentation on a hardware platform plays an integral role in both research and education.It will be used for veri .cation,as well as for undergraduate and graduate projects that providestudents with hands-on experience in a real sensor network testbed.This project will enablethe acquisition of the necessary hardware.Two newly developed graduate courses on multiusercommunications and wireless networking will bene .t greatly from this project.It is anticipatedthat by such close linking,research and education cross-fertilize each other within the frameworkof this proposal.Further,since the proposed architectures and related issues carry over to otherimportant classes of networks,the .ndings from this research will have an impact on a muchbroader class of wireless networks,including multihop cellular networks,that may soon becomesigni .cant for a major part of our society.The broader impact will also be felt through a broaddissemination of results and through current and future interactions with other universities.A-1

用传感器网络填充我们的世界需要对以可扩展和资源高效的方式通过通信网络连接和管理传感器节点的技术有基本的了解。所提出的研究涉及传感器网络架构、设计、评估和实施的综合计划它整合了无线网络和多用户通信领域的研究专业知识，并为加强本科生和研究生水平的传感器网络领域的学生研究和教育提供了大量机会。传感器网络实践的主导趋势是考虑密集的集合微小的计算和通信能力有限的传感器节点，全部通过at或ad hoc无线网络连接。然而，多用户通信的理论研究表明，可以通过节点之间复杂的协调来获得显着提高的性能，这需要更通用的无线电、层次结构，甚至可能是稀疏的因此，本研究的目标是：1）确定允许实施已理论研究的复杂传输方案的网络架构，2）分析此类在传感器网络的背景下设计方案并采用跨层方法设计新方案，3）实施这些方案并在实际测试台上验证其行为。该项目的智力优点在于加深了对重要的新兴无线网络类别的理解，以及试图将理论与实践结合起来。缩小理论提出的策略与实际实施之间不断扩大的差距对于理解和提高这些资源受限网络的性能和寿命至关重要。通过严格的分析方法，预计对网络信息理论的新兴领域做出贡献，从而导致节能和延迟约束协议设计的实质性进展。更广泛的影响部分地通过努力整合教学和研究来体现。硬件平台在研究和教育中发挥着不可或缺的作用。它将用于验证以及本科生和研究生项目，为学生提供真实传感器网络测试台的实践经验。该项目将使购买必要的硬件。两门新开发的关于多用户通信和无线网络的研究生课程将从该项目中受益匪浅。预计通过这种紧密的联系，研究和教育在该提案的框架内相互促进。此外，由于所提出的架构和相关问题适用于其他重要的网络类别，这项研究的结果将对更广泛的无线网络类别产生影响，包括多跳蜂窝网络，这可能很快就会变得重要.我们社会的大部分人都无法做到这一点。通过结果的广泛传播以及当前和未来与其他大学的互动，也将感受到更广泛的影响。A-1
