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

这个小型企业创新研究(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WLAN设备在挑战性的室内环境中的实时空间定位和跟踪，只需很少或根本没有预先设置和配置。提供经济实惠的本地化服务不仅可以更好地管理无线局域网，还可以提供更多基于位置的服务。特别是，拟议的研究解决了定位精度、一致性和跟踪性能方面的挑战。拟议的研究工作将为可扩展的、通用的本地化基础设施提供基础。这样的基础是将位置信息集成到无线设备中所必需的。这种无缝集成的结果可以比作现在通信几乎与每一种计算设备合作所获得的影响；在这两种情况下，许多新颖和令人兴奋的应用程序都是通过这些基础设施实现的。长期目标是仅使用现有通信流量就能知道所有无线设备的位置。这种通用的、可扩展的本地化系统将实现一系列新的监控、跟踪、路由和安全服务。例如，应急响应、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.
