FIND: Wireless Knowledge Infrastructure (WiKI)

在充满挑战和信息丰富的环境中，移动性对用户的本地信息产生了越来越大的需求，要求信息服务和网络协议具有新的能力。 无线知识基础设施（WiKI）项目开发了一个可扩展的通用系统层，其基础是应用编程语言和数据库系统概念的新思想-使用说明性语言和路由器、网络和主机状态的可组合视图-以允许根据现有网络条件和政策进行监测、事件检测和触发。声明式路由算法考虑应用、会话和网络状态信息，以在移动的设备和有线基础设施节点之间建立自适应路由。数据流的跨层和跨域集成视图暴露和抽象来自不同子系统和层的数据，为网络的“知识平面”提供了一个步骤。WiKI采取了一种探索性的方法，即使用802.11构建一个小规模的软件基础设施，以了解费城人口稠密的城市地区的无线挑战，并开发基于WiKI模型的原型服务。随着研究的进展，WiKI服务逐渐完善。更广泛的影响：最终目标是将WiKI平台、软件和服务纳入“无线费城”市政WiFI计划，该计划以其整体数字包容计划而闻名，该计划试图覆盖我市经济困难的家庭。

Mobility has created an increasing demand for information local to the user in a challenging and information-rich environment, demanding new capabilities from information services and network protocols. The Wireless Knowledge Infrastructure (WiKI) project develops an extensible general-purpose system layer based on new ideas for applying concepts from programming languages and database systems - the use of declarative languages and composable views of router, network and host state - to allow monitoring, event detection and triggering based on extant network conditions and policies. Declarative routing algorithms take into account application, session and network state information to set up adaptive routes among mobile devices and wired infrastructure nodes. Cross-layer and cross-domain integrated views of data streams expose and abstract data from different subsystems and layers, providing a step towards a "Knowledge Plane" for networks. WiKI takes an exploratory approach, namely building a small-scale software infrastructure using 802.11 to understand the wireless challenges of heavily populated urban areas in Philadelphia, and to develop prototype services based on a WiKI model. WiKI services are incrementally refined as the research progresses. Broader Impact: The end goal is incorporation of WiKI platforms, software and services into the "Wireless Philadelphia" municipal WiFI effort, notable for its integral Digital Inclusion program which attempts to reach economically disadvantaged households in our city.
