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

为使我们的世界充满传感器网络，需要对传感器节点与通信网络以可扩展和资源节约的方式连接和管理的技术有基本的了解。所提出的研究涉及传感器网络体系结构、设计、评估和实现的综合方案，该方案集成了无线网络和多用户通信领域的研究专业知识，并提供了许多机会来加强本科生和研究生在传感器网络领域的研究和教育。传感器网络实践的主要趋势是考虑具有有限计算和通信能力的微小传感器节点的密集集合，所有这些节点都通过A、O、O、C、E、O、C、C、C无线网络。然而，多用户通信中的理论研究表明，通过节点之间复杂的协调可以获得显著的性能改善，这需要更通用的无线电、层级，甚至可能是稀疏的有线连接。因此，提议的研究的目标是：1)识别允许实施已在理论上研究的复杂传输方案的网络结构，2)在传感器网络的环境中分析这些方案并设计采用跨层方法的新方案，3)实施这些方案并在真实测试平台上验证它们的行为。该项目的智力价值在于更好地理解了一类重要的新兴无线网络，缩小理论提出的策略与实际实施的策略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，有望对网络信息理论的新兴领域做出贡献，导致能量和时延受限协议设计的实质性进展。更广泛的影响部分体现在教学和研究的结合上。硬件平台上的实验在研究和教育中都起着不可或缺的作用。它将用于验证，以及为学生提供实际传感器网络测试实践经验的本科生和研究生项目。该项目将使学生能够获得必要的硬件。关于多用户通信和无线网络的两门新开发的研究生课程将从该项目中受益匪浅。预计通过如此紧密的联系，研究和教育将在该提案的框架内相互促进。此外，由于所提出的体系结构和相关问题延续到其他重要的网络类别，来自该研究的结论将对更广泛的无线网络类别产生影响，包括多跳蜂窝网络，这可能很快就会对我们社会的大部分人产生重大影响。更广泛的影响也将通过广泛传播结果以及通过目前和未来与其他大学的互动而感受到。
