We design an image processing pipeline that takes into account the background and foreground information of an image and then applies an adaptive encoding method which priorities more important regions of an image during encoding, in order to achieve the best quality image under a very strict size limit. We test our system with different types of RGB images that contain indoor and outdoor objects, buildings, and road signs. We empirically determine the tradeoffs between the system lifetime and the quality of broadcasted images, and determine an optimal set of parameters for our system, under user-specified constraints such as the number of available beacon devices, maximum latency, and life expectancy. We develop a smartphone application that takes an image and user requirements as inputs, shows previews of different quality output images, writes the encoded image into a set of beacons, and reads the broadcasted image back. Our evaluation shows that a set of 2–3 beacons is capable of broadcasting high-quality images (70% structurally similar to original images) for a year-long continuous broadcasting, and both the lifetime and the image quality improve when more beacons are used.","PeriodicalId":179120,"journal":{"name":"2017 IEEE/ACM Second International Conference on Internet-of-Things Design and Implementation (IoTDI)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128369475","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}

The stability of a platoon system is crucialso that each vehicle maintains a safety distance from itsproceeding vehicle and can take necessary actions to avoidcollisions. However, current centralized platoon maintenancemethod cannot meet this requirement. We suggest to use adecentralized platoon maintenance method, in which eachvehicle communicates with its neighbor vehicles and self-determines its own velocity. However, a vehicle needs toknow its distance from its preceding vehicle to determineits velocity, which is unavailable in vehicle communicationdisconnection caused by vehicle dynamics (i.e., node joinsand departures). Thus, a formidable challenge is: how torecover the platoon quickly in vehicle dynamics even when thedistance information is unavailable? To handle this challenge,we first profile a succeeding vehicle’s velocity to minimizethe time to recover the connectivity hole with its precedingvehicle and find that the profiles are almost the same at thebeginning regardless of its current velocity and distance to itspreceding vehicle. Accordingly, we devise a strategy, in whicha succeeding vehicle uses its stored common velocity profilewhen it is disconnected from its preceding vehicle and thenadjusts its velocity once the connection is built. Experimentalresults from simulation show the efficiency and effectivenessof our decentralized platoon maintenance method.","PeriodicalId":179120,"journal":{"name":"2017 IEEE/ACM Second International Conference on Internet-of-Things Design and Implementation (IoTDI)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117253632","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}

VLC is therefore a good match for indoor setups that need to support a large number of nodes with moderate bandwidth requirements. But designing a VLC system for worst-case operating conditions is more restrictive than necessary. This paper presents a software-based VLC system that adapts link sensitivity and capacity to match environment constraints. Compared to a fixed sensing scheme, an adaptive scheme increases channel capacity by almost an order of magnitude under favorable conditions or significantly extends the communication range. This adaptive link sensitivity allows communication even without a direct line of sight between two devices, opening new opportunities to use VLC systems in novel scenarios involving different types of embedded devices -- ranging from network nodes that only include a single Light Emitting Diode (LED), such as consumer electronics, toys, and wearables, to LED light bulbs that run Linux and provide an indoor VLC communication fabric.","PeriodicalId":179120,"journal":{"name":"2017 IEEE/ACM Second International Conference on Internet-of-Things Design and Implementation (IoTDI)","volume":"29 17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125791321","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}

Their proliferation has led to the emergence of crowdsensing/crowdsourcing services, where humans collect data about their environment (using phones), and servers aggregate the data for various application purposes of interest. With the emergence of social media, a common alternative form of human data entry has become media posts (e.g., on Twitter). This leads to the prospect of building crowdsensing services on top of social media content, exploiting humans as ``sensors\". In this paper, we develop one such service, called {em StoryLine}. The service detects and tracks physical urban events of interest to the user, such as car accidents, infrastructure damage (in the aftermath of a natural disaster), or instances of civil unrest. It offers an interface to client-side software that allows browsing such events in real time, as well as an interface for software applications to a structured representation of the events and their related statistics. The service embodies novel algorithms for real-time detection, demultiplexing, and tracking of physical events using social media data. In our evaluation with Twitter feeds, we show that our service outperforms two state-of-the-art baselines in event detection and demultiplexing. We also conduct two case-studies to show the effectiveness of the real-time event detection capability and event tracking performance of our system.","PeriodicalId":179120,"journal":{"name":"2017 IEEE/ACM Second International Conference on Internet-of-Things Design and Implementation (IoTDI)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121305089","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}

IoT platforms have emerged to integrate smart city services and city resources, and thus improve city performance in the domains of transportation, emergency, environment, public safety, etc. Despite the increasing intelligence of smart services and the sophistication of platforms, the safety issues in smart cities are not addressed adequately, especially the safety issues arising from the integration of smart services. Therefore, CityGuard, a safety-aware watchdog architecture is developed. To the best of our knowledge, it is the first architecture that detects and resolves conflicts among actions of different services considering both safety and performance requirements. Prior to developing CityGuard, safety and performance requirements and a spectrum of conflicts are specified. Sophisticated models are used to analyze secondary effects, and detect device and environmental conflicts. A simulation based on New York City is used for the evaluation. The results show that CityGuard (i) identifies unsafe actions and thus helps to prevent the city from safety hazards, (ii) detects and resolves two major types of conflicts, i.e., device and environmental conflicts, and (iii) improves the overall city performance.","PeriodicalId":179120,"journal":{"name":"2017 IEEE/ACM Second International Conference on Internet-of-Things Design and Implementation (IoTDI)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117248408","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}

SIoT is a new paradigm where IoT merges with social networks, allowing people and connected devices as well as the devices themselves to interact within a social network framework. Through an online survey with 60 potential users, we identified eight desired features for the SIoT, which were then clustered into four rule categories that can be programmed by end users and/or imposed by systems. The rules created by end users are used to reason about both devices and people in their social relationships to support automated decisions during runtime. Socialite uses ontology/semantic models for basic/low-level knowledge representation (e.g., device and user) to encapsulate the heterogeneity in devices from various manufacturers, and uses production rules (trigger-action programming) for high-level reasoning. With the ontology model, our reasoning supports both device type automation (e.g., current temperature from a thermostat) and capability-based automation (e.g., current temperature from any devices with the same capability). Furthermore, the Socialite rules leverage social relationships and device capabilities to facilitate collaboration by efficiently sharing configuration and information among users/friends and even with devices from people unknown to a user. In a 24-participant user study (12 with no programming experience), we found that Socialite was easy to learn and use, for both programmers and non-programmers. Participants were able to create automation based rules, social relationship involved rules, as well rules they created during the study.","PeriodicalId":179120,"journal":{"name":"2017 IEEE/ACM Second International Conference on Internet-of-Things Design and Implementation (IoTDI)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122013819","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}
