The growth of the Internet of Things (IoT) creates the possibility of decentralized systems of sensing and actuation, potentially on a global scale. IoT devices connected to cloud networks can offer sensing and actuation as a service enabling networks of sensors to grow to a global scale. But extremely large sensor networks can violate privacy, especially in the case where IoT devices are mobile and...
In this research we present a remote localization technique as an essential preprocessing step to enable Physical Analytics in the retail and hospitality sector. We studied two crowdsourced Wi-Fi data sources as potential inputs for fingerprinting-based positioning systems. These sources are non intrusively crowdsourced and can be easily acquired at almost any retail store. We evaluated our hypothesis...
To provide daily-life assistance appropriately by a service robot, the management of houseware's information in a room or a house is an indispensable function. Especially, the information about what and where objects are in the environment are fundamental and critical knowledge. We can track housewares with high reliability by attaching markers such as RFID tags to them, however, markerless housewares...
Fuel used by heavy duty trucks is a major cost for logistics companies, and therefore improvements in this area are highly desired. Many of the factors that influence fuel consumption, such as the road type, vehicle configuration or external environment, are difficult to influence. One of the most under-explored ways to lower the costs is training and incentivizing drivers. However, today it is difficult...
Performance of Cognitive Radio (CR) is affected by the estimation of availability of vacant channels based on traffic distribution observation of licensed users. Telecom traffic prediction at a particular instant depends on thorough knowledge of day of the week, hour of the day and instant of the hour. Distributed cooperative spectrum sensing is infrastructure based in which the sensor nodes themselves...
Traffic congestion is a major concern in metropolitan areas and a quick congestion assessment of large-scale network is required for modern traffic management referred to as Intelligent Transport Systems (ITS). However, ITSs are facing the challenge of real-time storage, retrieval and processing of a vast amount of collected data over a large-scale network. Compressed sensing (CS) is an efficient...
In this paper we provide an intelligent and convenient shopping cart, Intelligent Shopping Assistant System (ISAS). With ISAS, customers can concentrate on what he/she has to buy, and do not be bothered where he/she has to buy or it is want to buy. In contrast to conventional shopping cart, two modes of autonomous functions are added to ISAS in order to reduce the labor of customers for pushing goods...
This article presents a data audit system, which confirms that proper use of data is performed on the iKaaS platform (intelligent Knowledge as a Service) platform. The proposed data audit system can alleviate ambiguous anxiety of data owner about unauthorized use by providing measures to understand that illegal use of data cannot occur. This achievement is expected to support the construction of the...
This study presents the development of a system which can automatically recognize home appliances based on a dataset of electric consumption profiles. The authors report the creation of AGILASx, a dataset of 50 common home appliances and devices in the Philippines. The dataset is populated with 100 appliance signatures in .XML format acquired using plug-based sensors. Each appliance signature consists...
We present a publicly available benchmark database for the problem of hand posture recognition from noisy depth data and fused RGB-D data obtained from low-cost time-of-flight (ToF) sensors. The database is the most extensive database of this kind containing over a million data samples (point clouds) recorded from 35 different individuals for ten different static hand postures. This captures a great...
Wearable Devices (WD) are systems designed to do a specific task, these system are embedded in daily life personal objects. Usual transducers in wearable devices involve accelerometers gyroscopes, cameras etc. In WD is required to design efficiently in terms of power. Therefore, a new trend incorporates acoustic transducer that does not need a power supply to sense. They are very cheap and easy to...
In this paper, we present and implement a low-cost yet effective architecture that enables dynamic spectrum access (DSA) for any type of network. Our intention is to break the cost-scalability barrier and show that a complete system level solution for a database-assisted DSA system can be implemented with standard servers and inexpensive software configurable RF chips, thereby achieving economics...
A low-cost but high-accuracy mechanism for detecting falls is critical for many health and safety applications, including caring for the elderly. Existing approaches are unduly expensive and sensitive to user physique and biometrics. Additionally, most approaches were developed using limited, simulated fall data and often perform poorly in field tests. To resolve these issues, in this paper we propose...
In this work we investigate an auction mechanism for sharing available wireless bandwidth among competing cognitive radios. The bandwidth under consideration may be either in an unlicensed spectrum or in an unused licensed band. Spectrum sharing is achieved via a mechanism in which a cognitive radio acting as the auctioneer advertises spectrum availability to bidding cognitive radios and defines a...
This paper proposes a novel method for combining multiple fingerprint templates to improve the successful matching rate in fingerprint verification systems. Firstly, SVD is used to optimal aligning of two minutia sets. Then, based on the newly obtained overlapping area, we introduce a post-processing step to collect previously missing minutiae pairs due to nonlinear distortion. The overall advantages...
Traditional cognitive radio network is considerably constrained in the spectrum sensing and the access by its limited power, memory and computational capacity. Fortunately, the advent of cloud computing bring the potential to mitigate these constraints due to its vast storage and computational capacity. This paper focuses on the cloud-based cognitive radio spectrum access strategy and provides an...
On the Internet of the future, billions of physical objects will collect and exchange data that will be stored in the Cloud Computing. A bad storage structure of big data has a negative influence on the latency time during the client's requests. To solve this problem, we have proposed an Infrastructure as a Service (IaaS) for the input and the output of different files on servers' clusters. We have...
It has been shown that local magnetic field (MF) anomalies can be used in accurate global self-localisation with fingerprinting. However, MF anomalies can only affect limited areas, and the low discernibility of received local MF signals may result in many positions having the same MF-Location information in areas far away from disturbances. This is mainly due to the sensitivity limitations of sensors...
Target localization and tracking have the inseparable connection. On the one hand, localization is the basis of tracking. On the other hand, tracking can provide localization with prior information to correct the error of localization to some extent. At the same time, making the monitoring area be the grid area can let the localization and tracking system easy to be applied to different monitoring...
Cooperative Intelligent Transportation Systems (CITS) are being developed to make road traffic safer and more efficient. Vehicle to vehicle (V2V) communication plays an important role for the cooperative awareness of vehicles in all the CITS standards in EU, US, and Japan. Essentially the CITS application relies on the exchanged data by V2V messages (called Cooperative Awareness Message (CAM) in EU)...
