多定位技术融合的位置感知中间件

Location-aware Middleware Combining Multi-positioning Techniques

无论是普适计算还是物联网,定位都是其关键技术之一.为了解决现有的定位技术多面向某一特定应用开发、缺乏通用性等问题,构建了一个通用的实时位置感知中间件UbiRTLM.将应用服务从位置感知技术中分离出来,可以不需要更改原有的应用及服务而动态扩展新的定位技术.通过实验验证了UbiRTLM的定位精度及相关功能.结果表明:UbiRTLM能够满足大多数应用的精度需求并能处理相应的服务请求.

Localization is one of key technologies for whatever ubiquitous computing or Internet of Things.In order to solve the problem that existing positioning techniques were mainly developed for a specific application and lack of generability,we built a common location-aware middleware named UbiRTLM（Ubiquitous Real-time Localization Middleware） in this paper.The application service was separated from location-aware technique,and UbiRTLM allows you add dynamically new positioning technique without changing the existing applications and services.The positioning precision and related functions were validated by experimental test.The results showed that： UbiRTLM can meet the precision requirement of most applications and handle related service requests.
