城市移動應(yīng)用的環(huán)境模型
摘要
城市設(shè)置指的是主機(jī)的多樣化的網(wǎng)絡(luò)技術(shù)，從3G和有線寬帶、無線網(wǎng)絡(luò)、WiMAX、藍(lán)牙到最近的傳感器網(wǎng)絡(luò)。這些并存的網(wǎng)絡(luò)能提供豐富的移動應(yīng)用程序的情境感知輸入。迄今為止,絕大多數(shù)的情境感知的移動應(yīng)用專業(yè),如醫(yī)療保健和旅游,缺乏通用性和適應(yīng)性。這就是為什么需要一個能滿足未來大型網(wǎng)絡(luò)應(yīng)用的環(huán)境模型。本論文為解決這個問題，提出了一個通常足夠用于實現(xiàn)城市設(shè)置的環(huán)境模型，所要解決的問題是為貫穿整個網(wǎng)絡(luò)的廣泛的、多樣化的移動應(yīng)用提供環(huán)境感知服務(wù)。本文提出了一種對現(xiàn)有模型的分析,介紹了作者認(rèn)同的O + L模型(本體加邏輯)，以及能支持模型及其定性評估的原始服務(wù)架構(gòu)。
Context Modeling for Urban Mobile Applications
Abstract
Urban settings are host of diverse networking
technologies, from 3G and wired broadband to Wi-Fi,
WiMAX, Bluetooth and, more recently, sensor networks.
Potentially, these co-existing networks can provide rich
inputs to mobile applications that are context aware. To
date, the vast majority of context-aware mobile
applications are specialized, e.g. healthcare and
tourism, and they lack generality and adaptability. It is
therefore essential to use a context model that will match
the requirements of a large range of future urban
networks applications. The question addressed by this
paper is to propose an appropriate context model that is
general enough to be effective for urban settings, the
challenge being to provide the context-aware service to
a wide variety of mobile applications across all
networks. This paper presents an analysis of existing
models, introduces the O+L model (ontologies plus
logic) adopted by the authors, the original service
architecture that supports the model and its qualitative
eva luation.
