SBIR Phase I: On Generalizing Localization in Wireless Networks: Providing Low-Cost Solutions for Tracking and Security in Wireless LANs

该小型企业创新研究（SBIR）第一阶段项目将为无线局域网（WLAN）提供可扩展的空间定位服务。与有线网络不同，无线网络提供了在物理空间中定位任何传输设备的机会。在项目结束时，我们的单一框架将演示在具有挑战性的室内环境中对WLAN设备进行实时空间定位和跟踪，而很少或根本没有事先设置和配置。提供经济实惠的本地化不仅可以实现更好的WLAN管理，还可以实现其他基于位置的服务。特别是，拟议的研究解决了定位精度，一致性和跟踪性能的挑战。拟议的研究工作将提供一个可扩展的，通用的本地化基础设施的基础。这样的基础对于将位置信息集成到无线设备中是必要的。这种无缝集成所产生的影响可以与现在几乎每个计算设备都与通信合作所获得的影响相提并论;在这两种情况下，这些基础设施都能够实现许多新颖且令人兴奋的应用程序。长期目标是仅使用现有通信业务就能够知道所有无线设备的位置。这样一个通用的、可扩展的定位系统将实现一系列新颖的监控、跟踪、路由和安全服务。例如，紧急响应、库存跟踪和控制、几何网络路由和安全应用都将受益于广泛可用的低成本本地化。

This Small Business Innovation Research (SBIR) Phase I project will provide a scalable spatial positioning service for wireless Local Area Networks (WLAN). Unlike wired networks, wireless ones offer the opportunity to position any transmitting device in physical space. At the conclusion of the project, our single framework will demonstrate real-time spatial positioning and tracking of WLAN devices in challenging indoor environments with little or no prior set-up and configuration. Providing affordable localization will not only enable better WLAN management, but also will enable additional location-based services. In particular, the proposed research addresses the challenges of positioning accuracy, consistency, and tracking performance. The proposed research work will provide the foundation for a scalable, universal localization infrastructure. Such a foundation is necessary to integrate location information into wireless devices. The resulting impact of such a seamless integration can be likened to those obtained now that communication is partnered with nearly every computing device; in both cases many novel and exciting applications are enabled by these infrastructures. The long term goal is to enable the position of all wireless devices to be known using only the existing communication traffic. Such a universal, scalable localization system will enable a host of novel monitoring, tracking, routing and security services. For example, emergency response, inventory tracking and control, geometric network routing, and security applications would all benefit from widely available, low-cost localization.
