上下文感知计算是普适计算中支持用户活动的重要技术之一，它能够识别用户执行任务的上下文。为了实现上下文感知计算，计算机需要识别用户的位置。本文描述了一种使用来自用户计算机的无线电波在房间内进行位置检测的技术。所提出的技术必须具有足够的鲁棒性，以适应动态环境，并且只需要普通的网络设备，例如无线电信号发射器，而不需要特殊设备。我们建议通过无线节点之间的RSSI（接收信号强度指示符）的相对值来执行定位。此外，在使用绝对RSSI值进行定位的情况下，我们使用SVM（支持向量机）来找到分类标准（节点是在给定区域内部还是外部）。
Context-aware computing that recognizes the context in which a user performs a task is one of the most important techniques for supporting user activity in ubiquitous computing. To realize context-aware computing, a computer needs to recognize the user’s location. This paper describes a technique for location detection inside a room using radio waves from a user’s computer. The proposed technique has to be sufficiently robust to cater for dynamic environments and should require only ordinary network devices, such as radio signal emitters, without the need for special equipment. We propose performing localization by relative values of RSSI (Received Signal Strength Indicator) among wireless nodes. Furthermore, we use SVM (Support Vector Machine) to find the criteria for classification (whether a node is inside or outside a given area), in the case where absolute RSSI values are used for localization.
