NeTS-NOSS: AIDA: Autonomous Information Dissemination in RAndomly Deployed Sensor Networks

无线传感器网络的一个主要任务是将传感器读数传回中央主机，称为汇聚节点。因此，传感器网络的核心功能是节能、及时、健壮和安全地将数据从数据源传播到接收器。该项目旨在创建一种新的传感器网络体系结构AIDA，该体系结构使用分布式传感器节点的天线阵列来产生定向无线电波，该定向无线电波可以到达比传感器节点的单个天线更远的数量级。这种分布式天线阵是通过排列多个传感器节点的天线并在不同的阶段同时传输相同的信息来创建的，该项目探索了一种完整而连贯的策略来设计和实现随机部署的传感器网络中基于动态分布式天线阵形成的能量高效的数据分发。所追求的策略同时解决了从物理到MAC再到路由层的问题，包括传感器节点大小、天线设计(包括大小和效率)、传感器同步、传感器定位、低功率无线电以及MAC和路由协议。PIS将制作集成新无线电和天线的传感器节点原型，并在Purdu.现场测试一个小规模的AIDA传感器网络。广泛影响：结果将促进我们对分布式天线阵列形成的基本限制和在大规模传感器网络中的应用的理解。该项目中开发的算法、协议和系统架构，以及它们背后的理论，将对传感器网络技术产生重大影响。通过普渡大学的无线系统和应用中心，PIS将积极与行业合作伙伴分享他们的发现。在这个项目上支持的学生将有一个平衡的接触广泛的各种系统设计技术，这将是他们未来的职业生涯中有价值的。

A major task of a wireless sensor network is to disseminate sensor readings back to a centralized host, called the sink node. As such, a core functionality of the sensor network is energy-efficient, timely, robust, and secure dissemination of data from data sources to the sink. This project aims to create a new sensor network architecture, AIDA, that uses antenna arrays of the distributed sensor nodes to create directional radio waves that can reach order-of-magnitude farther than individual antennas of the sensor nodes. Such a distributed antenna array is created by aligning antennas of multiple sensor nodes and transmitting the same information simultaneously at different phases.The project explores a complete and coherent strategy for designing and implementing energy-efficient data dissemination based on dynamic distributed antenna array forming in randomly deployed sensor networks. The pursued strategy simultaneously addresses issues from the physical to the MAC to the routing layers, including sensor node size, antenna design including size and efficiency, sensor synchronization, sensor localization, low-power radio, and MAC and routing protocols. The PIs will prototype sensor nodes that integrate the new radios and antennas and field test a small-scale AIDA sensor network at Purdue.Broader Impact: The results will advance our understanding of the fundamental limits of distributed antenna array forming and applications in large-scale sensor networks. The algorithms, protocols, and system architectures developed in this project, and the theory underlying them, will have a significant impact on the sensor network technologies. Through the Center for Wireless Systems and Applications at Purdue, the PIs will actively share their findings with industrial collaborators. Students supported on this project will have a balanced exposure to a wide variety of system design techniques that will be valuable in their future careers.
