Device to Device Collaboration for Mobile Clouds in Drop Computing Drop计算中移动云的设备到设备协作
Radu-Corneliu Marin, Alexandru Gherghina-Pestrea, Alexandru Florin Robert Timisica, Radu-Ioan Ciobanu, C. Dobre
The large number of mobile devices existing nowadays has led to the evolution of mobile cloud computing towards bringing data and computations closer to the nodes. This has manifested first in the shape of fog and edge computing, where an additional communication and processing layer is added at the edge of the network. However, the fast adoption of the Internet of Things has shown the limitations of even this model, so the focus now is moving towards another layer that is one level below: the ad hoc network composed of the mobile devices themselves. One paradigm based on this model is Drop Computing, where nodes that need to do some computations first attempt to process them through the help of neighbor devices using close-range communication (such as Wi-Fi Direct or Bluetooth), and only then do they attempt to contact the fog/edge nodes or the cloud itself. In this paper, we propose an Android implementation of the device-to-device layer of Drop Computing. On top of this implementation, we present an application that creates a video collage from multiple photos using ffmpeg with the help of neighboring nodes through close-range communication using the HYCCUPS and Google Nearby frameworks. Through experiments on four Android devices, we show that our implementation can drastically decrease CPU usage per device, which in turn increases the overall quality of experience for Android users. Furthermore, the total battery consumption is lowered, since nodes have less computations to perform and the CPU cores spend less time in higher frequencies.
如今存在的大量移动设备已经导致移动云计算朝着使数据和计算更接近节点的方向发展。这首先以雾和边缘计算的形式表现出来,其中在网络边缘添加了额外的通信和处理层。然而,物联网的快速普及显示出这种模式的局限性,因此现在的焦点转向了下一层:由移动设备本身组成的自组织网络。基于该模型的一个范例是Drop Computing,其中需要进行一些计算的节点首先尝试通过使用近距离通信(如Wi-Fi Direct或蓝牙)的邻居设备的帮助来处理它们,然后它们才尝试联系雾/边缘节点或云本身。在本文中,我们提出了一个在Android上实现Drop Computing的设备到设备层。在此实现的基础上,我们提出了一个应用程序,该应用程序通过使用HYCCUPS和Google Nearby框架的近距离通信,在邻近节点的帮助下,使用ffmpeg从多张照片创建视频拼贴。通过在4个Android设备上的实验,我们发现我们的实现可以大幅降低每台设备的CPU使用率,从而提高Android用户的整体体验质量。此外,由于节点需要执行的计算更少,CPU内核在更高频率上花费的时间更少,因此降低了总电池消耗。

IoTSM: An End-to-end Security Model for IoT Ecosystems IoTSM:物联网生态系统的端到端安全模型
Joseph Bugeja, Bahtijar Vogel, A. Jacobsson, Rimpu Varshney
The Internet of Things (IoT) market is growing rapidly, allowing continuous evolution of new technologies. Alongside this development, most IoT devices are easy to compromise, as security is often not a prioritized characteristic. This paper proposes a novel IoT Security Model (IoTSM) that can be used by organizations to formulate and implement a strategy for developing end-to-end IoT security. IoTSM is grounded by the Software Assurance Maturity Model (SAMM) framework, however it expands it with new security practices and empirical data gathered from IoT practitioners. Moreover, we generalize the model into a conceptual framework. This approach allows the formal analysis for security in general and evaluates an organization's security practices. Overall, our proposed approach can help researchers, practitioners, and IoT organizations, to discourse about IoT security from an end-to-end perspective.
物联网(IoT)市场正在快速增长,新技术不断发展。随着这种发展,大多数物联网设备很容易受到损害,因为安全性通常不是优先考虑的特征。本文提出了一种新的物联网安全模型(IoTSM),可用于组织制定和实施开发端到端物联网安全的战略。IoTSM以软件保障成熟度模型(SAMM)框架为基础,但它通过新的安全实践和从物联网从业者那里收集的经验数据对其进行了扩展。此外,我们将模型推广到一个概念框架中。该方法允许对安全性进行一般的形式化分析,并评估组织的安全性实践。总的来说,我们提出的方法可以帮助研究人员、从业者和物联网组织从端到端角度讨论物联网安全。

IoT-NetSec: Policy-Based IoT Network Security Using OpenFlow IoT- netsec:使用OpenFlow的基于策略的IoT网络安全
Mehdi Nobakht, Craig Russell, Wen Hu, A. Seneviratne
The increasingly widespread adoption of the Internet of Things (IoT) has resulted in concerns about IoT security. Recently, there have been proposals to leverage software-defined networking (SDN) to augment IoT device security with network-level measurements. We argue that existing general-purpose security solutions using SDN are impractical for supporting today's home and corporate networks due to the high volume and rates of network traffic, differences in characteristics of IoT systems and computer networks, and limited resources in underlying network switches. To this end we propose IoT-NetSec, a framework that enables policy-based and fine-grained traffic monitoring of the network segments that include only IoT devices. We describe a prototype implementation and its integration with an SDN controller. The prototype implementation and simulations with three network service attacks (port scanning, SYN DoS Flooding and smurf DDoS) demonstrate IoT-NetSec feasibility in a network of real IoT devices.
物联网(IoT)的日益广泛采用引发了对物联网安全的担忧。最近,有人建议利用软件定义网络(SDN)通过网络级测量来增强物联网设备的安全性。我们认为,由于网络流量的高容量和速率、物联网系统和计算机网络的特征差异以及底层网络交换机的资源有限,使用SDN的现有通用安全解决方案对于支持当今的家庭和企业网络是不切实际的。为此,我们提出了IoT- netsec,这是一个框架,可以对仅包含物联网设备的网段进行基于策略和细粒度的流量监控。我们描述了一个原型实现及其与SDN控制器的集成。通过三种网络服务攻击(端口扫描、SYN DoS泛洪和smurf DDoS)的原型实现和模拟,证明了IoT- netsec在真实物联网设备网络中的可行性。

T. Tantidham, Yu Nandar Aung
Due to emerging disruptive technologies, Internet of Things (IoT) play a vital role for smart living domains, for examples, elderly and disabilities healthcare services and home safety and security monitoring and automation control services. These systems will send automatically an emergency call with home user information and location as a privacy data to public services like hospitals, police offices, or fire departments. This paper introduces emergency service for a Smart Home System (SHS) based on Ethereum blockchain with smart contract for decentralized handling access control among untrusted public services so called Home Service Providers (HSPs) and smart home IoT devices. Our SHS testbed consists of (1) smart home sensor manger equipped with Raspberry Pi (RPi) represented as an edge IoT gateway for gathering environmental sensor data, (2) HSP miners deployed Meteor and Ethereum platform, and (3) web-based applications for home users and HSP staffs. Furthermore, our contribution includes the integration of digital signature for the IoT device authentication, the One Time Passcode with QR code for HSP staff access control, and IPFS for manipulating emergency call from SHS in peers. Our implementation results focusing on HSP miners will be presented and analysed.

A Blockchain-Based Architecture for Integrated Smart Parking Systems 基于区块链的集成智能停车系统架构
Sabbir Ahmed, Soaibuzzaman, Mohammad Saidur Rahman, M. Rahaman
In this paper, we introduce an integrated smart parking system. The proposed integrated smart parking system brings multiple parking service providers together under a unified platform aiming to provide one-stop parking information services to the commuters in a smart city. However, the adaptation of such a system is prone to tempering while a massive amount of data is shared among different parties which raise concerns related to trust and performance. To address this challenge, we propose a blockchain-based architecture specific to the integrated smart parking systems. Finally, we present a set of design principles which shows the applicability of our proposed blockchain-based integrated parking system.

Everyday Life ToDo Display on Ceiling for Smart Living Space 日常生活待办事项吊顶显示,打造智能生活空间
Shigeyuki Hirai, Michi Takamura
Many commonly used household appliances and equipment include refrigerators, washing machines, intercoms, telephones, air conditioners, microwaves, and ovens; they communicate various information to the users by providing notifications using auditory displays. However, an occupied user may not pay attention to the notifications and/or cannot recognize simultaneous auditory alerts. Therefore, in this study, we propose a ceiling display system that displays information depending on the location of the users. This display system utilizes house ceilings as overhead visual displays that can update the users with various information simultaneously. This paper describes the different situations where appliances notify the users on completing a task; subsequently, we propose a concept for the ceiling display system in a smart house that will be introduced in the near future. In addition, the expected effectiveness of this system, some useful scenarios, and initial verifications of the visual notifications on the ceiling are described.
许多常用的家用电器和设备包括冰箱、洗衣机、对讲机、电话、空调、微波炉和烤箱;它们通过使用听觉显示提供通知,向用户传达各种信息。然而,被占用的用户可能不注意通知和/或不能识别同时的听觉警报。因此,在本研究中,我们提出了一个天花板显示系统,根据用户的位置显示信息。该显示系统利用房屋天花板作为头顶的视觉显示,可以同时向用户更新各种信息。本文描述了设备在完成任务时通知用户的不同情况;随后,我们提出了一个智能住宅天花板显示系统的概念,将在不久的将来引入。此外,还描述了该系统的预期有效性,一些有用的场景,以及天花板上视觉通知的初步验证。

LoRaIn: Making a Case for LoRa in Indoor Localization LoRaIn: LoRa在室内定位中的应用
Bashima Islam, Md Tamzeed Islam, J. Kaur, S. Nirjon
In this paper, we analyze the feasibility of using LoRa, an emerging low-power wide-area networking technology, in indoor localization. We define seven criteria upon which a wireless technology's prospect as an indoor localization system depends largely. For comparison, we take two other popular wireless technologies (BLE and WiFi) that have been previously proposed in many modern indoor localization systems. We deploy these three technologies in multiple line-of-sight and non-line-of-sight indoor scenarios including corridors, open spaces, spaces with a varying number of walls, and across floors of multi-storied buildings. Considering the coverage, stability and regularity of signals, accuracy of localization, responsiveness, power, and cost–we conclude that LoRa is a feasible choice for indoor localization solution, especially in wide and tall indoor environments like warehouses and multi-storied buildings.
本文分析了LoRa这一新兴的低功耗广域网技术在室内定位中的可行性。我们定义了无线技术作为室内定位系统的前景在很大程度上取决于七个标准。为了进行比较,我们以其他两种流行的无线技术(BLE和WiFi)为例,这两种技术先前在许多现代室内定位系统中被提出。我们将这三种技术应用于多个视距和非视距室内场景,包括走廊、开放空间、有不同数量墙壁的空间以及多层建筑的楼层。考虑到信号的覆盖范围、稳定性和规律性、定位精度、响应性、功耗和成本,我们认为LoRa是室内定位解决方案的可行选择,特别是在仓库和多层建筑等宽敞高大的室内环境中。

Combining Numerical and Visual Approaches in Validating Sleep Data Quality of Consumer Wearable Wristbands 结合数值和视觉方法验证消费者可穿戴腕带的睡眠数据质量
Zilu Liang, Mario Alberto Chapa Martell
The recent rise of the Quantified Self movement has witnessed a significant increase in the adoption of consumer wearable wristbands for sleep tracking. Nevertheless, data quality of these devices has been a main concern. This study aimed to validate a most popular consumer wristband, i.e. Fitbit Charge 2™, against medical devices. We proposed a new validation approach that combines numerical technique with visual aid for epoch-by-epoch comparison on sleep stages. We found that Fitbit Charge 2™ had low accuracy in detecting wake and reasonable accuracy in detecting light, deep, and REM sleep stages. The visual aid of scatter plots showed that Fitbit was more accurate in detecting deep sleep stage in the first half of a night and more accurate in detecting REM sleep stage in the second half of a night. Our results indicate that consumer wearable wristbands are not able to produce high quality data of sleep stages in ecological settings. Future studies should consider the effect of time on device accuracy and may resort to segmented modelling techniques to improve data quality.
最近兴起的“量化自我”运动见证了用于睡眠跟踪的消费者可穿戴腕带的显著增加。然而,这些设备的数据质量一直是一个主要问题。本研究旨在验证最受欢迎的消费者腕带,即Fitbit Charge 2™与医疗设备的对比。我们提出了一种新的验证方法,将数值技术与视觉辅助相结合,用于睡眠阶段的逐epoch比较。我们发现Fitbit Charge 2™在检测唤醒方面具有较低的准确性,而在检测浅睡眠、深度睡眠和快速眼动睡眠阶段具有合理的准确性。散点图视觉辅助显示,Fitbit对前半晚深度睡眠阶段的检测更准确,对后半晚快速眼动睡眠阶段的检测更准确。我们的研究结果表明,消费者可穿戴腕带不能在生态环境下产生高质量的睡眠阶段数据。未来的研究应考虑时间对设备精度的影响,并可能采用分段建模技术来提高数据质量。

Future studies should consider the effect of time on device accuracy and may resort to segmented modelling techniques to improve data quality.","PeriodicalId":437017,"journal":{"name":"2019 IEEE International Conference on Pervasive Computing and Communications Workshops (PerCom Workshops)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126628324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Requirements for a Reference Dataset for Multimodal Human Stress Detection 对多模态人体应力检测参考数据集的要求
Bhargav Mahesh, E. Prassler, Teena Hassan, Jens-Uwe Garbas
Stress is necessary for optimal performance and functioning in daily life. However, when stress exceeds person-specific coping levels, then it begins to negatively impact health and productivity. An automatic stress monitoring system that tracks stress levels based on physical and physiological parameters, can assist the user in maintaining stress within healthy limits. In order to build such a system, we need to develop and test various algorithms on a reference dataset consisting of multimodal stress responses. Such a reference dataset should fulfil requirements derived from results and practices of clinical and empirical research. This paper proposes a set of such requirements to support the establishment of a reference dataset for multimodal human stress detection. The requirements cover person-dependent and technical aspects such as selection of sample population, choice of stress stimuli, inclusion of multiple stress modalities, selection of annotation methods, and selection of data acquisition devices. Existing publicly available stress datasets were evaluated based on criteria derived from the proposed requirements. It was found that none of these datasets completely fulfilled the requirements. Therefore, efforts should be made in the future to establish a reference dataset, satisfying the specified requirements, in order to ensure comparability and reliability of results.
压力对于日常生活中的最佳表现和功能是必要的。然而,当压力超过个人特定的应对水平时,它就开始对健康和生产力产生负面影响。自动压力监测系统可以根据身体和生理参数跟踪压力水平,帮助用户将压力保持在健康范围内。为了构建这样一个系统,我们需要在包含多模态应力响应的参考数据集上开发和测试各种算法。这样的参考数据集应该满足临床和实证研究结果和实践的要求。本文提出了一组这样的要求,以支持建立多模态人体应力检测的参考数据集。这些要求涵盖了个人依赖和技术方面,如样本群体的选择、应激刺激的选择、多种应激模式的包括、注释方法的选择和数据采集设备的选择。现有的可公开获得的应力数据集是根据拟议要求得出的标准进行评估的。结果发现,这些数据集都没有完全满足要求。因此,未来应努力建立满足规定要求的参考数据集,以确保结果的可比性和可靠性。
