With the rapid development of Internet Things (IoT) and rise 5G communication networks automatic driving, millimeter wave (mmWave) sensing is emerging starts impacting our life workspace. mmWave can sense humans objects in a contactless way, providing fine-grained ability. In past few years, many techniques have been proposed applied various human applications (e.g., localization, gesture recognition, vital monitoring). We discover need comprehensive survey to summarize technology, platforms...
We present <sc xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">MicNest</small> : an acoustic localization system enabling precise drone landing. In , multiple microphones are deployed on a landing platform in carefully devised configurations. The carries speaker transmitting purposefully-designed pulses. may be localized as long the pulses correctly detected. Doing so is challenging: <italic xmlns:xlink="http://www.w3.org/1999/xlink">i)</i> because...
We present Acoustic Inertial Measurement (AIM), a one-of-a-kind technique for indoor drone localization and tracking. Indoor tracking are arguably crucial, yet unsolved challenge: in GPS-denied environments, existing approaches enjoy limited applicability, especially Non-Line of Sight (NLoS), require extensive environment instrumentation, or demand considerable hardware/software changes on drones. In contrast, AIM exploits the acoustic characteristics drones to estimate their location derive...
WiFi-based device localization is a key technology for smart applications, while most of which rely on LoS signals to work. However, in real-world indoor environments, very few are usable accurate localization. This paper presents Bifrost , novel hardware-software co-design cope with this practical problem. The core idea reinvent WiFi provide sufficient signals. Specifically, we present low-cost plug-in design leaky wave antenna (LWA) that can generate orthogonal polarized signals: On one...
This paper proposes Meta-Speaker, an innovative speaker capable of projecting audible sources into the air with a high level manipulability. Unlike traditional speakers that emit sound waves in all directions, Meta-Speaker can manipulate granularity region, down to single point, and location source. Additionally, source projected by is physical presence space, allowing both humans machines perceive it spatial awareness. achieves this leveraging fact nonlinear medium, which enables...
The ability to localize acoustic sources can greatly improve the perception of smart devices (e.g., a speaker like Amazon Alexa). In this work, we study problem concurrently localizing multiple with single device. Our proposal called <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Symphony</i> is first complete solution tackle above problem, including method, theory, and practice. method stems from insight that geometric layout microphones on...
Presents the guest editorial for this issue of publication.
In this paper, we propose a new model for information dissemination in mobile social networks.The dynamic equation of is modified.Moreover, investigate numerically the behavior on real scale-free site with exponent γ =1.08.We find that initial spreaders big out-degree can accelerate dissemination, and nodes large in-degree would be easier to spreader or become stiflers.
