摘要:

设计了一套基于信号强度RSS(received signal strength)的无基础设施定位算法。它无需借助任何其他的基础设施,只利用Wi-Fi;减轻了构建数据库的工作量,通过一种特殊的动态方式进行数据库的完善;通过热点的筛选,有效地减轻了周围无线信号的干扰;改进了基于RSS定位时的匹配算法,提高了定位准确度;定位操作简单,无需终端用户的复杂参与。本算法适合服务商在特定地点提供定位服务,通过部署专用的热点,有效地减轻周围环境的影响,提高定位服务的质量。

Abstract:

A RSS-based infrastructure-free localization algorithm was proposed,which is only based on Wi-Fi signals and does not require any additional infrastructure.It reduces the database construction cost by a special dynamic method.By picking the hot spot,it can effectively alleviate the interference from other wireless signals in the nearby region.It also enhances the RSS–based matching algorithm and hence improves the localization accuracy.The algorithm is easy to operate and doesn’t need any complex participation from end users.The algorithm is suitable for those who can provide positioning service in some special locations.Through the deployment of dedicated hot spots,it will reduce the environment interference and improve the quality of location-based service.
