Cross-Technology Communication is a promising solution proposed recently to the coexistence problem of heterogeneous wireless technologies in the ISM bands. The existing works use only the coarse-grained packet-level information for cross-technology modulation, suffering from a low throughput (e.g., 10bps). Our approach, called BlueBee, proposes a new direction by emulating legitimate ZigBee frames using a Bluetooth radio. Uniquely, BlueBee achieves dual-standard compliance and transparency by selecting only the payload of Bluetooth frames, requiring neither hardware nor firmware changes at the Bluetooth senders and ZigBee receivers. Our implementation on both USRP and commodity devices shows that BlueBee can achieve a more than 99% accuracy and a throughput 10,000x faster than the state-of-the-art CTC reported so far.
跨技术通信是近年来针对异构无线技术在ISM频段内共存问题提出的一种很有前途的解决方案。现有的工作仅使用粗粒度的分组级信息进行跨技术调制,其吞吐量较低(例如10bps)。我们的方法,称为BlueBee,通过使用蓝牙无线电模拟合法的ZigBee帧,提出了一个新的方向。独特的是,BlueBee通过只选择蓝牙帧的有效载荷实现了双标准遵从性和透明度,不需要在蓝牙发送者和ZigBee接收器更改硬件和固件。我们在USRP和商品设备上的实施表明,BlueBee可以实现超过99%的准确率,吞吐量比目前报道的最先进的CTC快10,000倍。

Augmented reality (AR) applications greatly benefit from direction estimation. In current AR devices, direction estimation is enabled by power hungry technologies such as GPS, management of inertial data and video processing. We present a low-complexity eyewear prototype capable of obtaining directional information from a set of environmental radio sources by using a multi-antenna system patented by Wagoo LLC. Eyewear devices are the natural match for this technology under the assumption that user line of sight represents the main reference for user interaction and orientation. In the demonstration, the prototype detects when a user aims at objects or people that are associated to standard Bluetooth Low Energy emitters (beacons) with a current 30° sensitivity and 5% error rate.
增强现实(AR)应用从方向估计中获益良多。在当前的AR设备中,方向估计是通过耗电技术实现的,如GPS、惯性数据管理和视频处理。我们提出了一种低复杂性的眼镜原型,能够通过使用Wagoo LLC专利的多天线系统从一组环境射电源中获取方向信息。在假设用户视线代表用户交互和方向的主要参考的情况下,眼镜设备是这种技术的自然匹配。在演示中,当用户瞄准与标准蓝牙低能量发射器(信标)相关的物体或人时,该原型会以30°的电流灵敏度和5%的错误率检测用户。

Individual localization services seldom satisfy the requirements for accurate, robust, punctual, and seamless location information. To enhance the provisioning, a set of challenges has to be addressed, pertaining to handover, fusion, and integration of individual localization services. In the following, we advertise the Standardized Localization Service (SLSR), a middleware architecture for achieving those goals. We instantiate the SLSR in a office-like indoor environment and evaluate its performance in a specifically designed testbed for evaluation of indoor localization approaches. Our results typify the contributions of different functional components envisioned in the SLSR on its overall performance.
单个的定位服务很少能满足对精确、健壮、准时和无缝的位置信息的要求。为了增强供应,必须解决一系列挑战,这些挑战与各个本地化服务的移交、融合和集成有关。在下文中,我们将介绍标准化本地化服务(SLSR),这是一种实现这些目标的中间件体系结构。我们在类似办公室的室内环境中实例化了SLSR,并在专门设计的测试平台中评估了其性能,以评估室内定位方法。我们的结果代表了SLSR中设想的不同功能组件对其整体性能的贡献。

Hierarchical Subchannel Allocation for Mode-3 Vehicle-to-Vehicle Sidelink Communications 模式3车对车侧链路通信的分层子信道分配

In this poster we present a graph-based hierarchical subchannel allocation scheme for V2V sidelink communications in Mode-3. Under this scheme, the eNodeB allocates subchannels for in-coverage vehicles. Then, vehicles will broadcast directly without the eNodeB intervening in the process. Therefore, in each communications cluster, it will become crucial to prevent allocation conflicts in time domain since vehicles will not be able to transmit and receive simultaneously. We present a solution where the time-domain requirement can be enforced through vertex aggregation. Additionally, allocation of subchannels is performed sequentially from the most to the least allocation-constrained cluster. We show through simulations that the proposed approach attains near-optimality.
在这张海报中,我们提出了一种基于图的V2V副链路通信的分层子信道分配方案。在此方案下,eNodeB为覆盖车辆分配子信道。然后,车辆将广播直接eNodeB干预过程。因此,在每个通信集群中,由于车辆不可能同时发送和接收,因此防止时域分配冲突就变得至关重要。我们提出了一种通过顶点聚合来实现时域要求的解决方案。此外,子通道的分配从分配约束最大的集群到分配约束最小的集群依次执行。我们通过模拟表明,所提出的方法达到了接近最优性。

We have completed the collection of one of the richest accurately annotated mobile dataset of modes of transportation and locomotion. To do this, we developed a highly reliable Android application called DataLogger capable of recording multisensor data from multiple synchronized smartphones simultaneously. The application allows real-time data annotation. We explain how we designed the app to achieve high reliability and ease of use. We also present an evaluation of the application in a big-data collection (750 hours, 950 GB of data, 17 different sensor modalities), analysing the data loss (less than 0.4%) and battery consumption (≈ 6% on average per hour). The application is available as open source.

BatTracker: High Precision Infrastructure-free Mobile Device Tracking in Indoor Environments 蝙蝠追踪器:室内环境中高精度无基础设施移动设备跟踪

Continuous tracking of the device location in 3D space is a popular form of user input, especially for virtual/augmented reality (VR/AR), video games and health rehabilitation. Conventional inertial based approaches are well known for inaccuracy caused by large error drifts. Computer vision approaches can produce accuracy tracking but have privacy concerns and are subject to lighting conditions and computation complexity. Recent work exploits accurate acoustic distance measurements for high precision tracking. However, they require additional hardware (e.g., multiple external speakers), which adds to the costs and installation efforts, thus limiting the convenience and usability. In this paper, we propose BatTracker, which incorporates inertial and acoustic data for robust, high precision and infrastructure-free tracking in indoor environments. BatTracker leverages echoes from nearby objects and uses distance measurements from them to correct error accumulation in inertial based device position prediction. It incorporates Doppler shifts and echo amplitudes to reliably identify the association between echoes and objects despite noisy signals from multi-path reflection and cluttered environment. A probabilistic algorithm creates, prunes and evolves multiple hypotheses based on measurement evidences to accommodate uncertainty in device position. Experiments in real environments show that BatTracker can track a mobile device's movements in 3D space at sub-cm level accuracy, comparable to the state-of-the-art infrastructure based approaches, while eliminating the needs of any additional hardware.
在3D空间中持续跟踪设备位置是一种流行的用户输入形式,特别是在虚拟/增强现实(VR/AR)、视频游戏和健康康复中。众所周知,传统的基于惯性的方法由于较大的误差漂移而导致不准确。计算机视觉方法可以产生准确的跟踪,但有隐私问题,受光照条件和计算复杂性的影响。最近的工作利用精确的声距离测量来进行高精度跟踪。然而,它们需要额外的硬件(例如,多个外部扬声器),这增加了成本和安装工作,从而限制了便利性和可用性。在本文中,我们提出了蝙蝠跟踪器,它结合了惯性和声学数据,在室内环境中实现了鲁棒、高精度和无基础设施的跟踪。蝙蝠追踪器利用来自附近物体的回波,并利用它们的距离测量来纠正基于惯性的设备位置预测中的误差积累。它结合了多普勒频移和回波幅度,可以可靠地识别回波和物体之间的关联,尽管多径反射和杂乱环境中存在噪声信号。概率算法根据测量证据创建,修剪和演变多个假设,以适应设备位置的不确定性。在真实环境中的实验表明,蝙蝠追踪器可以在3D空间中以亚厘米级的精度跟踪移动设备的运动,与最先进的基于基础设施的方法相媲美,同时无需任何额外的硬件。

Fog computing, the distribution of computing resources closer to the end devices along the cloud-to-things continuum, is recently emerging as an architecture for scaling of the Internet of Things (IoT) sensor networking applications. Fog computing requires novel computing program decompositions for heterogeneous hierarchical settings. To evaluate these new decompositions, we designed, developed, and instrumented a fog computing testbed that includes cloud computing and computing gateway execution points collaborating to finish complex data analytics operations. In this interactive demonstration we present one fog-specific algorithmic decomposition we recently examined and adapted for fog computing: a multi-execution point linear regression decomposition that jointly optimizes operation latency, quality, and costs. The demonstration highlights the role fog computing can play in future sensor networking architectures, and highlights some of the challenges of creating computing program decompositions for these architectures. An annotated video of the demonstration is available at [5].
雾计算,即沿着云到物连续体更靠近终端设备的计算资源分布,最近作为扩展物联网(IoT)传感器网络应用的架构而出现。雾计算需要对异构层次设置进行新的计算程序分解。为了评估这些新的分解,我们设计、开发并检测了一个雾计算测试平台,其中包括云计算和计算网关执行点,它们协作完成复杂的数据分析操作。在这个交互式演示中,我们介绍了一种我们最近研究并适应于雾计算的特定于雾的算法分解:一种多执行点线性回归分解,它可以共同优化操作延迟、质量和成本。该演示强调了雾计算在未来传感器网络架构中可以发挥的作用,并强调了为这些架构创建计算程序分解的一些挑战。该演示的注释视频可在[5]找到。

There is the long-standing assumption that radio communication in the range of hundreds of meters needs to consume mWs of power at the transmitting device. In this paper, we demonstrate that this is not necessarily the case for some devices equipped with backscatter radios. We present LOREA an architecture consisting of a tag, a reader and multiple carrier generators that overcomes the power, cost and range limitations of existing systems such as Computational Radio Frequency Identification (CRFID). LOREA achieves this by: First, generating narrow-band backscatter transmissions that improve receiver sensitivity. Second, mitigating self-interference without the complex designs employed on RFID readers by keeping carrier signal and backscattered signal apart in frequency. Finally, decoupling carrier generation from the reader and using devices such as WiFi routers and sensor nodes as a source of the carrier signal. An off-the-shelf implementation of LOREA costs 70 USD, a drastic reduction in price considering commercial RFID readers cost 2000 USD. LOREA's range scales with the carrier strength, and proximity to the carrier source and achieves a maximum range of 3.4 km when the tag is located at 1 m distance from a 28 dBm carrier source while consuming 70 μW at the tag. When the tag is equidistant from the carrier source and the receiver, we can communicate upto 75 m, a significant improvement over existing RFID readers.
长期以来,人们一直认为,数百米范围内的无线电通信需要在发射设备上消耗毫瓦的功率。在本文中,我们证明了对于一些配备反向散射无线电的设备来说,情况并非如此。我们提出了一种由标签、读取器和多个载波发生器组成的LOREA架构,克服了现有系统(如计算射频识别(CRFID))的功率、成本和范围限制。首先,产生窄带反向散射传输,提高接收器的灵敏度。其次,通过保持载波信号和反向散射信号在频率上分开,减少了RFID阅读器上使用的复杂设计,从而减轻了自干扰。最后,将载波生成与读取器解耦,并使用WiFi路由器和传感器节点等设备作为载波信号源。一个现成的LOREA实现成本为70美元,考虑到商用RFID阅读器的成本为2000美元,价格大幅下降。LOREA的距离随载波强度和与载波源的距离而变化,当标签距离28dbm载波源1 m时,LOREA的最大距离为3.4 km,而标签的功耗为70 μW。当标签与载波源和接收器的距离相等时,我们可以在75米的距离内进行通信,这是对现有RFID读取器的重大改进。

We explain how to obtain a highly versatile and precisely annotated dataset for the multimodal locomotion of mobile users. After presenting the experimental setup, data management challenges and potential applications, we conclude with the best practices for assuring data quality and reducing loss. The dataset currently comprises 7 months of measurements, collected by smartphone's sensors and a body-worn camera, while the 3 participants used 8 different modes of transportation. It comprises 950 GB of sensor data, which corresponds to 750 hours of labelled data.

Mitigating Erroneous Wake-ups 减少错误唤醒
Pub Date : 2017-11-06 DOI: 10.1145/3131672.3136980

We propose a novel method for mitigating erroneous wake-ups that are commonly associated with ultra-low power wake-up receivers. Recent research in low-power protocols has demonstrated significant improvements in energy-efficiency by employing ultra-low power wake-up receivers. However, due to the low-complexity receiver structures adopted, wake-up receivers are susceptible to external interference, which can cause the detection of non-existent wake-ups. The occurrence of these erroneous wake-ups wastes precious energy resources, thereby negating the potential energy savings in employing wake-up receivers. We address this challenging problem by extracting time-domain features from the output of the wake-up receiver, and construct a classifier to distinguish between correct and erroneous wake-ups. We describe the design of the proposed wake-up classifier and present preliminary results.
我们提出了一种新的方法来减轻通常与超低功耗唤醒接收器相关的错误唤醒。最近对低功耗协议的研究表明,采用超低功耗唤醒接收器可以显著提高能源效率。然而,由于采用了低复杂度的接收机结构,唤醒接收机容易受到外界干扰,从而可能会检测到不存在的唤醒。这些错误唤醒的发生浪费了宝贵的能源资源,从而抵消了使用唤醒接收器可能节省的能源。我们通过从唤醒接收器的输出中提取时域特征来解决这个具有挑战性的问题,并构建一个分类器来区分正确和错误的唤醒。我们描述了所提出的唤醒分类器的设计,并给出了初步的结果。
