用传感器网络填充我们的世界需要对连接和管理具有可扩展和资源e通信网络的传感器节点的技术有基本的了解。字母系数方法。拟议的研究涉及传感器网络架构、设计、评估和实施的综合计划，该计划集成了无线网络和多用户通信领域的研究专业知识，并为本科生和研究生在传感器网络领域加强学生的研究和教育提供了许多机会。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，所有传感器节点都通过a连接。无线网络。然而，多用户通信的理论研究表明，通过节点之间复杂的协调可以大幅提高性能，这需要更通用的无线电、层次结构，甚至可能是稀疏的有线连接。因此，提出的研究目标是：1)确定允许实现理论研究的复杂传输方案的网络架构，2)在传感器网络环境中分析这些方案并采用跨层方法设计新的方案，3)实现这些方案并在实际测试平台上验证其行为。该项目的智力价值在于提高了对重要的新兴无线网络类别的理解，并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策略之间日益扩大的差距对于理解和改善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新兴领域的贡献将导致能源电子领域的实质性进展。延迟约束协议设计。更广泛的影响在某种程度上是通过e来体现的。努力将教学与科研相结合。硬件平台上的实验在研究和教育中都扮演着不可或缺的角色。它将用于验证，以及本科生和研究生项目，为学生提供在真实传感器网络测试平台的实践经验。这个项目将能够获得必要的硬件。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中受益。我从这个项目中获益良多。预计通过这种密切联系，研究和教育将在本建议的框架内相互促进。此外，由于所提出的架构和相关问题延续到其他重要的网络类别，因此。这项研究的结果将对更广泛的无线网络产生影响，包括多跳蜂窝网络，这些网络可能很快就会成为我们社会的重要组成部分。更广泛的影响还将通过结果的广泛传播以及通过当前和未来与其他大学的互动来感受到。a - 1

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
