SGER: Small Antennas for Angle of Arrival Determination and Accurate Localization

ECCS-0742054 Stefano Basagni，东北大学这项研究的重点是探索解决方案，使小型，能量受限的无线传感器节点自定位，即，以计算它们相对于绝对或相对定位系统的坐标。典型的无线传感器网络（WSNs）应用，需要准确的定位包括灾难恢复和独立辅助生活应用。节点的位置意识显然是必要的，因为一个感测到的事件应该报告沿着，它happened.Since许多无线传感器网络应用程序的情况下，GPS是不是一个可行的选择，定位协议已被提出，提供节点的位置。特别地，已经观察到，无线电信号的节点间范围和到达角（AoA）的同时部署可以有效地用于以显著的精度定位节点。虽然已经提出了用于测量节点间范围的技术，以实现准确的估计，确定的AoA仍然是广泛未知的领域在无线传感器网络。本研究将探讨设计一个物理和电气小，低功耗的多元素天线阵列，可以提供明确的AoA为RF signal.Intellectual优点：无线传感器网络是一个重要的和不断增长的领域，无数的应用程序，其中大部分依赖于准确的定位。确定准确的AoA与RF技术在很大程度上仍然是未开发的无线传感器网络。从天线设计到广泛的模拟，再到实际硬件实验，从多个角度提供结果。更广泛的影响：为传感器节点提供不依赖基础设施的自定位能力，将提高灾难恢复和辅助生活应用的响应能力。 无线传感器网络社区也将受益于这里提出的调查。一个研究生将通过这一努力得到支持。

ECCS-0742054Stefano Basagni, Northeastern UniversityThis research focuses on exploring solutions that will allow small, energy-constrained wireless sensor nodes to self-localize, i.e., to compute their coordinates with respect to an absolute or relative positioning system. Typical wireless sensor networks (WSNs) applications that require accurate localization include disaster recovery and independent assisted living applications. Nodal location awareness is clearly necessary because a sensed event should be reported along with where it happened.Since for the scenario of many WSNs application GPS is not a viable choice, localization protocols have been proposed that provide nodal positions. In particular, it has been observed that the concurrent deployment of inter-nodal range and the angle of arrival (AoA) of the radio signal can be effectively used for localizing nodes with remarkable accuracy. While techniques for measuring the inter-nodal range have been proposed that achieve accurate estimation, determining the AoA is still widely uncharted territory in WSNs. This research will investigate the design of a physically and electrically small, low-power multiple element antenna array that can provide unambiguous AoA for RF signals.Intellectual Merit: WSN are an important and growing area, with countless applications most of which relay on accurate localization. Determining accurate AoA with RF techniques is still largely unexplored for WSNs. This research intends to provide results from multiple points of view: From antenna design, to extensive simulations to real-hardware experimentation.Broader Impact: Providing sensor nodes with the ability to self-localize without relying on infrastructure will improve the response in disaster recovery and in assisted living applications. The WSN community will also benefit by the investigation proposed here. A graduate student will be supported by this effort.
