Abstract

The market for 802.11 based wireless LAN technology has matured greatly in recent years and it is now being used in homes, offices, cafes, airports, and even in hot spots in urban areas. Each 802.11 frame transmitted from 802.11 equipped devices contains information on signal strength and noise. By measuring the signal strength information included in frames sent from a fixed node to a mobile node, it is possible to approximate the distance between the fixed and mobile node. However, as many research papers pointed out, positioning based on received signal strength is difficult, since 802.11 is very susceptible to the effects of various factors, such as reflection or attenuation of the signals. In this paper, we take into account these behavioral characteristics of 802.11 and propose a different approach, where instead of trying to estimate the exact location of a mobile node, we only try to detect incoming movement or access within a given proximity range. Since most recent mobile devices available in the market incorporate or have the capability to add-on 802.11 technologies, mobile users can utilize motion sensing applications without relying on other technologies such as RF-tags or infrared.

使用802.11移动设备的接近运动检测

近年来，基于802.11的无线局域网技术的市场已经非常成熟，它现在被用于家庭、办公室、咖啡馆、机场，甚至城市地区的热点。从配备802.11的设备传输的每个802.11帧都包含有关信号强度和噪声的信息。通过测量从固定节点发送到移动节点的帧中包含的信号强度信息，可以近似确定固定节点与移动节点之间的距离。然而，正如许多研究论文所指出的那样，基于接收到的信号强度进行定位是困难的，因为802.11非常容易受到各种因素的影响，例如信号的反射或衰减。在本文中，我们考虑了802.11的这些行为特征，并提出了一种不同的方法，而不是试图估计移动节点的确切位置，我们只尝试检测给定接近范围内的传入运动或访问。由于市场上最新的移动设备包含或有能力添加802.11技术，移动用户可以利用运动传感应用程序，而不依赖于其他技术，如射频标签或红外。
