This paper presents a new solution using the Weibull function for approximating the Bluetooth signal strength distribution in the data training phase. May 2009; Simon Hay. This paper presents an experimental study of the feasibility of using multiple wireless technologies simultaneously for location estimation. I need Bluetooth since I use a Magic Mouse. This paper examines the value of the method in a marketing application. This paper compares techniques, discusses the benefits and drawbacks to facilitate the accurate method at the appropriate time. Such protocols usually aim at minimizing communication overhead, evenly distributing roles among the participating nodes, as well as controlling the network topology. The ubiquitous computing community has widely researched the use of 802.11 for the purpose of location inference. For example, enforcing close physical proximity to a patient when using a barcode medication administration system (BCMA) can mitigate the consequences of unsafe barcode scanning workarounds. We firstly define the problem of Beacon Deployment for Positioning (BDP) and provide several theoretic bounds on the number of required beacons to gain sufficient understanding on its performance behaviour. : Place lab: Device positioning using radio beacons in the wild. Indoors, however, even coarse location remains unavailable. The SELFLOC algorithm infers the user location by selectively fusing location information from multiple wireless technologies and/or multiple classical location algorithms in a theoretically optimal manner. Les interfaces sans fil de ces objets connectÃ©s Ã©mettent pÃ©riodiquement des informations, certaines sont spÃ©cifiques aux utilisateurs et permettent par effet de bord dâidentifier et de suivre leur dÃ©placements. We envisage the global scale Place Lab, consisting of an open software base and a community building activity as a way to bootstrap the broad adoption of location-aware computing. Not affiliated The use of sparsely deployed WiFi access points is discussed in detail. indoor localization system, to greatly increase the number of controllable To verify the discovered contexts, we compare them to the communities detected by the Louvain method, showing a strong correlation between the results of the two methods. A new measurement model is added to the particle filter engine to process incoming Bluetooth data. In this paper, we present a novel brain computer interface based home This affects signal intensity and therefore limits th e practicality of traditional fingerprinting approaches bas ed on receiver signal strength (RSSI) measurements. B-PniP is a zero-configure opportunistic direct M2M communication protocol between neighbor devices to achieve the autonomous communication concept with zero-configuration. Moreover, a software prototype that implements TM in a geographical information system (GIS) is introduced.

Dismiss Join GitHub today. This publication has not been â¦ LBS can provide libraries with new tools to market their products and enhance their services and the time to optimize the hyperlocal web. For this purpose, we have used the technique of RSSI fingerprinting and tested three different algorithms. 3, pp. The solution is based on the inquiry response rate of Bluetooth technology. We propose a fixed-lag particle filter algorithm to process data incrementally. La deuxiÃ¨me partie prÃ©sentent les contributions de la thÃ¨se qui visent Ã proposer de nouvelles mÃ©thodes de suivi, analyser les performances de celles-ci face aux mÃ©thodes existantes et dans le cas particulier de lâapplication de crowd-localisation, Ã proposer des mÃ©thodes de suivi respectueuse de la vie privÃ©e. In earlier work, we described a prototype of this system and stated our intention to deploy it on a large scale. The effectiveness of the indoor positioning service is critically analyzed. This paper presents a graph model based approach to indoor tracking that offers a uniform data management infrastructure for different symbolic â¦ Lastly, we conclusively show how crowdsourcing for context can be used towards a user-centric framework for privacy management during beacon encounters. Finally, we also conduct some much focused simulations to assess the scalability of our protocol in very large networks and multiple mobile assets. We propose two location algorithms, selective fusion location estimation (SELFLOC) and region of confidence (RoC), which can be used in conjunction with classical location algorithms such as triangulation, or with third-party commercial location estimation systems. The rise of Bluetooth-equipped devices in personal consumer electronics and in in-car systems has revealed the potential to develop Bluetooth sensor systems for applications in intelligent transportation systems. As a result of this deterministic address assignment, the IID. participants (e.g. For an observational dataset, gathered by mobile phones, we Amongst those, Bluetooth has been widely known for its low-power consumption, small maintenance cost, as well as its wide-spread amongst the commodity devices. It is thus different from traditional OD matrix estimation approaches that relied on successive steps of modelling and of statistical inferences. We present experiments on extracting movement and interaction activities from sociometric badge signals and show how to use them for detection of sub-communities. Â© 2008-2020 ResearchGate GmbH. In fact, cellular phones with GPS receivers and 802.11 wireless LAN are already becoming available. One way to keep these costs under control is to automate some or all of the management aspects in the system, reducing or even removing the need for human interaction. Traditionally, the OD matrix estimation has solely been based on traffic counts collected by networks of magnetic loops. Type. Use of the platform is illustrated through a practical example, which allows a user's current working desktop to follow them as they move around the environment. Bluetooth Tracking without Discoverability. Location awareness is an important capability for mobile computing. Outdoor location-based services are now prevalent due to advances in mobile technology and GPS. 2, pp. Not only does this model offer a compact visualisation of the distribution of intervals, it also supports an innovative temporal query mechanism that relies on geometries in the two-dimensional space. We validate this attack by developing the first Software-defined Radio (SDR) based sniffer that allows full BT spectrum analysis (79 MHz) and implements the proposed de-anonymization technique. I've been having a chronic problem with my Logitech mouse, after digging in with Big Sur I've found what looks like the cause, but it makes no sense: My 2018 MBP keeps connecting to a phantom Bluetooth device. LNCS, vol. Thus, the model describes the world much as users themselves would. discuss the possibility of employing the described method and techniques for With Bluetooth Low Energy beacons, one of the latest technologies for providing proximity and indoor tracking, the current identifiers that characterize a beacon are not sufficient for ordinary users to make informed privacy decisions about the location information that could be shared. This thesis takes place in a context with over 600 Bluetooth detectors installed in the City of Brisbane. Finally, we present the deployment experience at an office building. It should be possible to make better use of the multiple devices around us by coming up with ways of integrating and combining them, while leveraging the specific strengths of some devices and minimizing the individual weaknesses of others. Using the popular Reality Mining dataset, we further demonstrate the extraction of co-location activities and use them to automatically infer the structure of social subgroups. A frequently employed form of human-machine interaction is via prompts-for example, prompting the user to perform the next step in a sequence of actions. Used together with the Lower Address Part (LAP), which is present in all frames transmitted, this enables tracking of the piconet master (e.g., the car BT interface, or a smartphone when connected to a headset), thereby debunking the privacy guarantees of BT. Both the research community and developers in industry have identified the need for a clearly defined vocabulary and programming framework for location technologies. is described. ... One of the earliest uses of Bluetooth positioning and tracking technology is the Aalborg Zoo, the largest zoological garden in Denmark. Therefore, we give first an overview of the general characteristics of Bluetooth technology today, going deeper in the analysis of Bluetooth stackâs layers and the security features offered by the specifications. The design of the Horus system aims at satisfying two goals: high accuracy and low computational requirements. This can be done either by exhaustively searching all possible PINs (but without interacting with the victim devices), or by mounting a so-called middle-person attack. In: ICT 2003: Proceedings of the 10th International Conference on Telecommunications, vol. Bluetooth has been identified as a potential location technology that mobile consumer devices already support, easing deployment and maintenance. This study indicates that the reliability and accuracy of the fingerprint database is improved with the Weibull function approach. 2003.

We point to three types of potential vulnerabilities in the Bluetooth standard, version 1.0B. In: Proceedings of the 23rd International Conference on Distributed Computing Systems Workshops, April 2003, pp. In this paper we investigate an alternative: connection-based tracking. This study focuses on achieving unambiguous user positioning using practical Bluetooth Low Energy (BLE) beacons with multiple discrete power levels. 480–483 (2003), Cheung, K., Intille, S., Larson, K.: An inexpensive Bluetooth-based indoor positioning hack. Understanding how people interact and socialize is important in many contexts from disease control to urban planning. Finally, we However, the main bottleneck of such crowd-sourcing localization systems is a bootstrapping stage, where lack of contributions by users results in no accuracy guarantee and frequent unnecessary prompting for users' input, even for explored areas. The convergence of the neural network and the solution feasibility to the defined problem are both theoretically proven. It uses Bluetooth Low Energy (also known as BLE or Bluetooth 4.0) to wirelessly connect to your mobile device and transmit data to that device through the connection. Treating the current state of the environment as common ground between computers and users provides new ways of interacting with information systems. B-LIDx protocol is the protocol for locationing the mobile device in indoor. This work comprehensively investigates the power consumption of hard drives to determine typical runtime power profiles. wireless networks has fostered a growing interest in location-aware Conference Paper. I have an Apple watch and want to leave Bluetooth active so it stays connected, but also turn off discoverability for other devices. one or more of the meta-features, effectively revealing preferences of Indoors, however, even coarse location remains unavailable. We exploit proximity between Bluetooth devices attached to people and objects for estimating 1) room-level proximity of people and objects, and 2) mutual proximity between moving people and objects. We show that the proximity information exchanged between several devices can be updated at a rate of more than 1 Hz by effectively choosing the timing parameters of Bluetooth inquiry mechanism. After this analysis of the specifications, we study how known vulnerabilities have been exploited with a comprehensive list of known attacks, which poses serious threats for the users. As these networks grow in size and complexity, their management becomes increasingly costly, for instance in terms of equipment, software, and people. In: UbiComp 2008: Proceedings of the 10th International Conference on Ubiquitous Computing (September 2008), Bahl, P., Padmanabhan, V.: RADAR: an in-building RF-based user location and tracking system. In android, Bluetooth is a communication network protocol, which allow a devices to connect wirelessly to exchange the data with other Bluetooth devices. The obtained structure in the form of clusters of concerts and participants is then interpreted using meta-information about music genres, band origins, stages, and dates of the performances. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. 2, pp. We have empirically validated the proposed algorithms using wireless LAN and Bluetooth technology. We investigate the differences between a number of possible policies to evaluate the case for apportionment based on energy and usage data collected over the course of a year. We implement this exact real-time tracking system and use it as a foundation for a novel application that applies location-based restrictions on access control. Outdoor location-based services are now prevalent due to advances in mobile technology and GPS. The protocol's evaluations are performed by measuring the time for finding the location of a mobile device in actual environment and aligning the time spent in services using the B-PniP. Further, the role of link-strength Datasets that capture this specific aspect of human life have increased in size and availability over the last few years. The proposed localiza- tion system fully integrates these device discovery procedures into the infrastructure-based network of Bluetooth access points that provides the wireless connectivity inside a building. We employed an Infinite Relational Model (IRM) in order to analyze the collected data and to recover the structure of the network related to participants' music preferences. We end by presenting an early evaluation of YanuX and by discussing the status of our work along with directions for further research. In this paper we present RADAR, a radio-frequency (RF) based system for locating and tracking users inside buildings. Lastly, we study the identified privacy attack in the wild, capturing BT traffic at a road junction over 5 days and with the sniffer moving at vehicular speeds, demonstrating that our system can re-identify hundreds of users and infer their commuting patterns. LBS are divided into three nonexclusive categories, such as requests for things or information about existing location, receiving alerts, and tracking individuals or groups. Meanwhile, Blue- tooth is increasingly widely deployed due to its low power consumption and cost. By analysis of the real world experimental output, we present results that depict a more realistic view of the clustering problem, regarding adapting to environmental conditions and the quality of topology control. We have been exploring the possibility of building applications that present user interfaces pervasively distributed across different co-located devices. For example, this snippet sets the duration to 300: We currently live surrounded by many different computing devices. would be to have standardized category and privacy labels, produced by beacon providers or an independent third-party. However, little research has been done to understand the properties of Bluetooth wireless signal amongst the current Bluetooth-based tracking systems. We demonstrate a radio beacon-based approach to location, called Place Lab, that can overcome the lack of ubiquity and high-cost found in existing location sensing approaches. Indoor applications require a precise estimation that GPS can not achieve. We address the issues that hinder its performance due to the real environment conditions and provide a deployable protocol. A Belgian shopping mall served as a real-life test setting for the methodology. Home Browse by Title Proceedings LoCA '09 Bluetooth Tracking without Discoverability. In: Beigl, M., Intille, S.S., Rekimoto, J., Tokuda, H. Over the past year, approximately 50 staff members have used the system daily with a set of trial applications, Proceedings on Privacy Enhancing Technologies. Our prototype Beacon+ design enables secure location sensing applications such as real-time tracking of hospital assets (e.g., infusion pumps). The increasing storage capacity and necessary redundancy of data centers and other large-scale IT facilities has drawn attention to the issue of reducing the power consumption of hard drives. Battery consumption. Master of Science dissertation, Bruno, R., Delmastro, F.: Design and analysis of a Bluetooth-based indoor localization system. The field tests show the effectiveness of the information filter-assisted positioning method, which improves the horizontal positioning accuracy of indoor navigation by about 17% compared to the static fingerprinting positioning method, achieving a 4.2 m positioning accuracy on the average, and about 16% improvement compared to the point Kalman filter. probability of sharing an online friendship. For an observational dataset, gathered using mobile phones, we analyze the problem of identifying transient and non-important links, as well as how to highlight important social interactions. And, this missing piece makes incentivizing energy reduction a challenge. We evaluate the real-world performance of our algorithms through experiments carried out with a running system in a realistic environment. The main advantage is that this reduces the need for network planning, which reduces the costs of operating the system. --Massachusetts Institute of Technology, Dept. Outdoor location-based services are now prevalent due to advances in mobile technology and GPS. Exploiting the advantages of wireless communication protocols is not only for telecommunication purposes, but also for payments, interaction with intelligent vehicles, etc. Speed detection is assisted to correct the outliers of position estimation. We aim to extract proximal context from Bluetooth stream data, using an incremental, Bayesian nonparametric framework that estimates the number of contexts automatically. The field tests show that the new algorithm proposed applying information filter with speed detection improves the horizontal positioning accuracy of indoor navigation with about 17% compared to the static fingerprinting positioning method, achieving a 4.2 m positioning accuracy on the average, and about 16% improvement compared to the point Kalman filter. If a device can determine its own location then it can infer its surroundings and adapt accordingly. This paper briefly presents the functionality, and the architecture of an indoor positioning service based on this technology. We found that our algorithms can reduce a network to approximately half the original size while still retaining an accuracy level comparable to the original "full" network. The authors draw on their experiences with campus and building-scale location systems to identify the technological and social barriers to a truly ubiquitous deployment. This sampling scheme is especially suitable for pervasive computing as the computational requirements remain constant in spite of growing data. We highlight the significance of wide fin- gerprints, constructed through scanning multiple channels, for achieving high localization accuracy. It combines empirical measurements with signal propagation modeling to determine user location and thereby enable location-aware services and applications. CILoS is an indoor localization system based on CDMA mo- bile phone signal fingerprinting. The Bluetooth wireless technology is an emerging technology originally designed as a short-range connectivity solution for personal, portable, and handheld electronic devices. By analysis of the real-world experimental output, we present results that depict a more realistic view of the target tracking problem, regarding power consumption and the quality of tracking information. (2010b) present a Bluetooth locating solution in a reduced Bluetooth infrastructure area by using RSSI probability distributions. Once the userâs position has been uniquely determined the same filter is demonstrated to track the userâs absolute position to sub-metre accuracy. By detecting when the foot is stationary and applying zero velocity corrections a pedestrianâs relative movements can be tracked far more accurately than is possible using uncorrected inertial navigation. 775–784.

Buildings consume a significant portion of the total delivered energy. How Does A Bluetooth â¦ The availability of Bluetooth devices for most phones and the existence of a number of GPS equipped phones in a crowd of phone users enable us to design a Bluetooth aided mobile phone localization strategy. Evaluating target-tracking protocols for wireless sensor networks that can localise multiple mobile assets can be a very challenging task. As the fixed-lag particle filter process a small chunk of data when it comes and does not need to be restarted, its execution time is significantly shorter than that of the Gibbs sampling. festival participants form. Empirical tests show that these requirements hold. Time intervals are conventionally represented as linear segments in a one-dimensional space. A prototypical payment scenario at cash-desks in a store proves the concept, where customers are required to securely show their electronic store card, i.e., bring their mobile device into a near, non-interfering zone to their cashier. By receiving the beacon coverage status from a user's device, the cloud server can unambiguously pinpoint the user's location and react correspondingly.

There are software tools available which allow brute-force discovery of non-discoverable devices, an early example of which is RedFang, but this is usually too complex for a minimal hardware configuration and not necessary for data collection purposes associated with ITS. Sentient computing systems, which can change their behaviour based on a model of the environment they construct using sensor data, may hold the key to managing tomorrow's device-rich mobile networks. parameter to distinguish between observations, we demonstrate that weak links, We conclude by arguing why Bluetooth tracking offers significant advantages for tracking mass event visitors with respect to other and more prominent technologies, and outline some of its remaining deficiencies. low-cost stationary beacons and mobile host devices 1032–1043 (2004), Schilit, B.N., LaMarca, A., Borriello, G., Griswold, W., McDonald, D., Lazowska, E., Balachandran, A., Hong, J., Iverson, V.: Challenge: Ubiquitous location-aware computing and the place lab initiative.
