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.

无线传感器网络的一项主要任务是将传感器读数传递回到集中式主机，称为接收器节点。因此，传感器网络的核心功能是节能，及时，健壮且安全的数据从数据源传播到水槽。 该项目旨在创建一个新的传感器网络体系结构AIDA，该架构使用分布式传感器节点的天线阵列来创建与传感器节点的单个天线更远的高度级别的定向无线电波。 这种分布式天线阵列是通过对齐多个传感器节点的天线创建的，并在不同阶段同时传输相同的信息。该项目探索了一种完整而连贯的策略，用于设计和实现基于动态分布式天线阵列在随机部署的传感器网络中形成动态分布式天线阵列。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，包括尺寸和效率，传感器同步，传感器定位，低功率无线电以及MAC以及路由协议。 PIS将原型传感器节点进行原型传感器节点，以整合新的无线电和天线，并在Purdue的小型AIDA传感器网络中测试。Broader的影响：结果将提高我们对分布式天线阵列形成的基本限制以及在大型传感器网络中应用的基本限制。该项目中开发的算法，协议和系统体系结构以及它们为基础的理论将对传感器网络技术产生重大影响。 PIS通过普渡大学的无线系统和应用中心，将与工业合作者积极分享他们的发现。 该项目支持的学生将对各种系统设计技术进行平衡，这将在其未来的职业中很有价值。
