位置是移动的服务的关键过滤器，包括导航或广告。然而，在建筑物内和室内空间中的定位和定位可能是具有挑战性的，在室内空间中，用户花费他们的大部分时间，并且在室内空间中，最广泛使用的定位系统（即，诸如GPS（全球定位系统）的全球导航卫星系统）的信号不可用。在这方面，无线局域网（WLAN）（例如，Wi-Fi）可通过使用启用WLAN的装置（例如，智能电话）来测量并匹配由接入点广播的信号的接收信号强度（RSS）而用于定位目的。这种方法的挑战是，需要精确的RSS地图，测量RSS可能受到许多因素的影响，包括环境的动态和设备的方向和类型。本文提供了一个路径损耗模型，以产生RSS地图自动从平面图，并介绍了一种基于代理的仿真方法来研究不同的定位方法。这为减少与WLAN定位研究相关的时间和工作量提供了一条途径。
Location is a key filter for mobile services, including navigation or advertising. However, positioning and localization inside buildings and in indoor spaces, where users spend most of their time and where the signals of the most widely-used positioning system, i.e. Global Navigation Satellite Systems such as GPS (Global Positioning System), are not available, can be challenging. In this regard, Wireless Local Area Networks (WLAN), e.g. Wi-Fi, can be used for positioning purposes by using a WLAN-enabled device, e.g. a smartphone, to measure and match the Received Signal Strength (RSS) of a signal broadcast by an access point. The challenges of this approach are that accurate maps of RSS are required, and that measuring RSS can be affected by many factors, including the dynamics of the environment and the orientation and type of a device. This paper provides a path-loss model to produce RSS maps automatically from floor plans and introduces an agent-based simulation approach to investigate different positioning methods. This provides a pathway to reduce the time and effort associated with WLAN positioning research.
