In the mobile industrial human machine interaction (HMI) based on wireless sensor networks, the engineer has to manually select the target machine from a long list which may lead to wrong connection and waste of time. We observe that the engineer should face to the machine during the interaction to ensure that the machine works accurately, and this characteristic makes the proximity estimation algorithm...
We propose a system in which it allows the user to contact or make an alert during any emergency situation to the appropriate service provider directly using this application. Though there are several apps in the market, what makes our application special is that it is completely in our Tamil language. Here the user has to download and install the application along with all the required details. In...
According to the human physiological sensor communication needs of transmitting information rapidly and gathering data to the information node conveniently, the mobile's feature of communication fast and use easily is used as the gathering node for forwarding data and applying data. The study on the implementation methods of wireless sensor data interface and the open-frame of the software are carried...
In this article, we consider a service model based on network proximity and using Bluetooth. In this connection, we consider services based on the Core Bluetooth as well as services based on Bluetooth Low Energy. In particular, we present our vision on the applicability of Bluetooth Low Energy for positioning applications. This paper also provides specific models for Bluetooth network proximity based...
With the rapid increase in data and multimedia services, demand for positioning has increased especially in complex indoor environment which often needs to determine the location information of the mobile terminal. There is a lack of accuracy and robustness in current indoor positioning system. This paper designs and implements an indoor positioning system based on iBeacon. We adopt Gaussian filter...
We report a low cost mobile EEG system for characterizing cortical auditory responses. The system is built using commercial off-the-shelf components and each unit costs less than $200. It measures seven EEG channels plus one audio channel (envelope only), and communicates the data to external devices via Bluetooth. A novel implementation was pursued in order to support local signal compression using...
The Physical Web is a generic term describes interconnection of physical objects and web. The Physical Web lets to present physical objects in a web. There are different ways to do that and we will discuss them in our paper. Usually, the web presentation for a physical object could implement with the help of mobile devices. The basic idea behind the Physical Web is to navigate and control physical...
In this paper, we proposed data communication method based on inaudible sound which the most people cannot listen to at near field. The proposed method can transmit some bits data as using mixed high frequencies which are mapped at each data bit. Besides, the proposed method increases the accuracy of data transmission as using cyclic redundancy check for prevention of transmission error. To evaluate...
In this paper, we discuss the physical web projects based on network proximity for Smart Cities. In general, the Physical Web is an approach for connecting any physical object to the web. With this approach, we can navigate and control physical objects in the world surrounding mobile devices. Alternatively, we can execute services on mobile devices, depending on the surrounding physical objects. Technically,...
Prosthetic hand control based on the acquisition and processing of surface electromyography signals (sEMG) is a well-established method that makes use of the electric potentials evoked by the physiological contraction processes of one or more muscles. Furthermore intelligent mobile medical devices are on the brink of introducing safe and highly sophisticated systems to help a broad patient community...
There is a demand for a way for blind persons to receive information at any time and in any place. This is impossible to realize with existing user interfaces using voice output, so this paper introduces the world's first a wristwatch-style refreshable braille display. This braille display has 8 braille cells and 16 input switches. It is controlled from a host computer via the Bluetooth communication...
Mobile Device Clouds are becoming a reality with the quantitative and qualitative upgrades on mobile devices such as smart-phones and tablets. This proliferation renders mobile devices capable of initiating sophisticated cyberattacks especially when they coordinate together and form a distributed mobile botnets which we call “MobiBots”. MobiBots infect a large number of mobile devices and schedule...
As smartphones have recently become one of the most popular devices worldwide, various convenient applications are being released. Now smartphones not only provide the ordinary internal processes such as dialing or receiving phone calls, sending text messages, and doing mobile banking wherever we are, but they also are beginning to control various other devices that are part of our lives. Through...
In recent years, mobility models have been reconsidered based on findings by analyzing some big datasets collected by GPS sensors, cell phone call records, and Geotagging. To understand the fundamental statistical properties of the frequency of serendipitous human encounters, we conducted experiments to collect long-term data on human contact using short-range wireless communication devices which...
Delay-tolerant networking effectively extends the network connectivity in the time domain, and endows communications devices with enhanced data transfer capabilities. Network coding on the other hand enables us to approach the information capacity of networks by allowing intermediate nodes to process data en route. Both of these were major principal breakthroughs in mobile and wireless communications...
The contradiction between dynamic user traffic and fixed data plans has drawn increasing attention in the field of mobile applications. In this paper we build a data plan sharing system named INDAPSON to consider a scenario where some smartphone users have surplus data traffic and are willing to help others download data. Virtual credits can be gained as reward, which can be used to ask for future...
The main aim of the research presented in this paper was to investigate ‘how can collaborative middleware based CWE(Collaborative Working Environments), combined with Bluetooth technology, enhance the communications of mobile users for digital media technology education.’ This research activity outlines a collaborative middleware that has been developed on Smartphone technology and enables the creation...
The paper studies the colored image (JPEG) transmission over mobile Bluetooth network using Enhanced Data Rate (EDR) packets. The paper uses the 2DH3 EDR Asynchronous Connectionless (ACL) packets. It presents the proposed chaotic interleaving technique to improve a transmission of colored images over Bluetooth systems. Also, it studies different interleaving schemes for this purpose. A comparison...
The profusion of wireless enabled mobile devices in daily life routine and advancement in pervasive computing has opened new horizons to analyse and model the contextual information. This contextual information (for example, proximity data and location information) can be very helpful in analysing the human behaviours. Wireless proximity data can provide important information about the behaviour and...
The unexpected magnitude and scale of natural and human-induced disasters have impelled the search and rescue teams around the world to seek for newer and more innovative equipments to enhance their efficiency. Earthquakes, Cyclones, tsunamis and other natural disasters leave the terrain not only difficult for navigation, but also dangerous for human search and rescue teams. Human rescue teams are...
