Poster abstract: NDP — A novel device-free localization method with little efforts

While device-free localization (DFL), i.e., target without carrying any devices, is attractive, the need for a significant degree of pre-deployment effort is a key challenge. In this paper, we proposed the NDP method, which do not assume knowledge of the placement layout, including the parameters of the transceivers. The key intuition is that all of the distorted wireless signals caused by the target, even the many from unknown transceivers, are constrained the presence of the target(s). Despite the absence of any explicit pre-deployment calibration, NDP yields a 80^th percentile error of 1.8m which is much butter than the 6.2m, 5.8m and 5m yielded by the three state-of-the-art algorithms from prior work.
