SBIR Phase II: Scalable Location Data Management

这个小型企业创新研究第二阶段项目旨在设计、实施和测试提供基于位置的服务的可扩展方法，特别强调移动电话应用。这类应用的例子包括对静态和动态地理围栏的持续监测、构建动态移动社交网络和移动电子商务。第二阶段的工作将开发方法，以推动基于位置的计算技术的效率，并为隐私管理和移动电源管理等更复杂的功能开发方法，这将对更广泛地采用基于位置的应用程序至关重要。目前，位置数据是通过不断移动配备了基于位置的传感器的物理对象来生成的，例如基于GPS和Wi-Fi的标签。这些数据集的数据管理方法需要处理高更新率、大量历史位置数据和基于位置的触发器，当移动对象的位置满足特定标准(例如，如果对象超出明确定义的边界)时，基于位置的触发器会发出警报。支持具有这些要求的应用程序的现有方法是不可伸缩的。该项目更广泛的优点包括开发一种具有潜在巨大商业价值并满足新兴市场需求的技术。例如，对于手机市场，这些基于位置的服务预计将从2007年的4.64亿美元增长到2011年的逾110亿美元。如果成功，基于位置的服务在消费者和企业市场的潜在影响可能是巨大的。

This Small Business Innovation Research Phase II project aims to design, implement, and test scalable methods for providing location-based services, with a special emphasis on mobile cell phone applications. Examples of such applications include continuous monitoring of static and dynamic geo-fences, building dynamic mobile social networks, and mobile e-commerce. The Phase II effort will develop methods to push the efficiency of the location-based computation techniques, and develop methods for more sophisticated features such as privacy management and mobile power management, which will be crucial for the wider adoption of location-based applications. Location data is currently generated by continually moving physical objects equipped with location-based sensors, such as GPS and Wi-Fi based tags. Data management methods for these datasets require dealing with high update rates, large volumes of historical location data, and location-based triggers that raise an alert when the location of a moving object meets certain criteria (for example, if an object is beyond a well-defined boundary). Existing methods for supporting applications that have these requirements are not scalable. The broader merits of this project include the development of a technology that has a potentially large commercial value and addresses an emerging market need. For example, for the cell phone market, these location-based services are projected to grow from $464M in 2007 to over $11B by 2011. If successful, the potential impact in both consumer and enterprise markets for location-based services could be substantial.
