Poor air quality in urban areas is becoming an important problem that needs to be addressed. This paper presents the system architecture of project Urb@nEcoLife for compilation of environmental data using low-cost data sensors. Although there are several proposals dealing with sensor networks, most of them focus on solving partial problems. Urb@nEcoLife is a comprehensive proposal that develops a...
This paper presents a scheme which aims to track patients in hospitals and to generate the suggestion information to the patients. In this scheme, hardware like location tracking devices such as GPS, WiFi positioning system, Bluetooth Low Energy (BLE), and RFID is not required. Instead, the proposed system entirely relies on the existing data in the Hospital Information System (HIS). The data analytics...
Vacuum technology is a very widespread area. Nowadays, a broad variety of applications can be found to be using vacuum and vacuum related monitoring. Vacuum profile for different applications can be different, but whatever that may be, monitoring it is an essential part of any such application. Thus, this paper describes the development of one such vacuum profile monitoring system that can be re-purposed...
The past decades have seen the IT revolution impact the medical field, with numerous solutions for permanent monitoring, automated measurements and decision making support systems. Most of the current work focuses on life-critical or long-term monitoring solutions. However, we still need to invest more effort into the automation of classical tests. Doctors in ENT, neurologists and work medicine specialists...
With the increasing popularity of the Internet of Things applications, investors are more willing to invest on small digital electronic products and seek business opportunities. At the same time, along with the improvement of the data processing method, people want to get more accurate data. This paper presents an application that using Arduino and Bluetooth electronic scale to connect to smart phones...
The mute/deaf individuals have a communication problem dealing with other people. It is hard for such individuals to express what they want to say since sign language is not understandable by everyone. This paper is to develop a Data Acquisition and Control (DAC) system that translates the sign language into text that can be read by anyone. This system is called Sign Language Translator and Gesture...
This paper presents an implementation of a tree network topology which serves as the network backbone for a wireless sensor network (WSN) that is composed out of advanced Bluetooth low energy (BLE) wireless technology. Bluetooth LE supports the star network topology; however the tree network topology is not supported. To implement a tree topology, three different nodes are designed: the central or...
Wearable sensors are widely used for data collection in many applications. Ssensor nodes have also been applied for real-time applications, e.g. for ECG analysis or activity and fall detection. Processing of the sensor data is either done on an external device or on the node itself. While on-node processing reduces data rate and increases battery life, development and testing can be time-consuming...
Late arrival to jobs and meetings is a critical problem in a number of domains, such as building construction. Smart phones are a promising platform for detecting late arrivals and notifying affected parties due to the variety of sensors they possess, persistent Internet connection, and access to a user's calendar data. This paper presents a power-efficient cyber-physical approach to indoor/outdoor...
Intelligent Transportation Systems (ITS) are growing worldwide and new technologies are naturally being part of them. Wireless communication systems are widely used in ITS applications requiring short and long range information interchange useful to prevent accidents, plan a route, collect tolls, navigate over the internet, etc. Basically, there are two important applications of short range wireless...
It is still difficult to assess the real danger posed by Bluetooth-propagated malware. BlueBat is an effort to build and deploy a practical honeypot for capturing in-the-wild samples and empirically study malware prevalence. This paper describes the design and implementation of a first prototype, focusing on Bluetooth worms propagating over the OBEX Push service. We develop and perform initial field...
The wireless sensor network discussed in this article is one with Web interface based on radio frequency connection, information-driven star topology and energy-saved mode are used, the energy of each sensor node is reduced and secure management of each sensor node is improved.
In this paper, we present the technical details and the challenges we faced during the development and evaluation phases of our wearable indoor guiding system which consists of a virtual personal assistant guiding the user to his/her desired destination. The main issues that will be discussed can be classified in three categories: context detection, real-time 3D rendering and user interaction.
