在普适计算中，识别用户执行任务的上下文的上下文感知计算是支持用户活动的最重要技术之一。要实现情景感知计算，计算机需要识别用户的位置。这篇文章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。拟议的技术必须足够强大，以适应动态环境，并且应该只需要普通的网络设备，如无线电信号发射器，而不需要特殊设备。我们提出通过无线节点之间的RSSI(接收信号强度指示器)的相对值来进行定位，并且我们的系统支持节点的移动性。我们在节点可移动的环境中评估我们的系统的性能。
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, and also our system support the node mobility. We evaluate the performance of our system in the environment where the node is movable.
