INTEGRATED SENSING: Ontology Based Radios

无线通信对于协调应急工作至关重要。然而，各种类型的单位（消防，警察，联邦调查局和无人值守传感器）不一定能够访问公共无线电架构。为了实现无线通信的高度灵活性和可扩展性，无线波形的处理必须在软件中执行：即，“软件无线电”。将算法从硬件迁移到软件可以提高功能水平，但前提是在运行时建立通信协议。我们提出了一种方法来建立通信明确维护自我意识和通信的知识的操作的communicationnodes。 知识的自我意识和交流是基于维护一个明确的、声明性的知识库或交流的“本体论”。 因此，我们将这个概念称为“基于本体的无线电”（OBR）。 本体捕获感兴趣领域的基本术语（概念）以及概念之间的关系。 本体可以用DARPA Agent Markup Language（DAML）表示，并且使用定理证明器离线地处理或者使用专家系统引擎在真实的时间中处理。 OBR的主要思想是通信节点“理解”要传输的信息内容、自身的能力和目的单元的能力。 拟议项目的目标是开发一个概念验证，展示不同类型的通信节点之间的优化动态互操作性，特别是无人值守传感器以及应急响应团队使用的无线电。

Wireless communication is essential for coordination of emergencyresponse efforts. However, the various kinds of unit (fire, police,FBI and unattended sensors) do not necessarily have access to commonradio architectures. To achieve high levels of flexibility andscalability for wireless communication, the processing of the wirelesswaveforms must be performed in software: i.e., "softwareradio". Migrating algorithms from hardware to software can increasethe level of functionality but only if the communication protocols areestablished at run time. We propose an approach to establishingcommunication by explicitly maintaining self-awareness andcommunication of knowledge about the operation of the communicationnodes. The self-awareness and communication of knowledge is based onthe maintenance of an explicit, declarative knowledge base or"ontology" of communication. Hence, we refer to the concept as"Ontology Based Radio" (OBR). An ontology captures the basicterminology (concepts) of the domain of interest and the relationshipsamong the concepts. Ontologies can be expressed in the DARPA AgentMarkup Language (DAML), and processed either off-line using a theoremprover or in real time using an expert system engine. The main ideaof OBR is that the communication nodes ``understand'' the contents ofinformation to be transferred, their own capabilities and capabilitiesof the destination units. The goal of the proposed project is todevelop a proof of concept that demonstrates optimized dynamicinteroperability between different kinds of communication node,especially unattended sensors as well as radios used by emergencyresponse teams.
