Mobile healthcare services have received growing attention due to the rapid technical advancement of sensor devices, sensor networks, and mobile data transmission. Healthcare monitoring services, in general, lack the needed sophistication for the acquisition of the huge amount of healthcare data generated from mobile users. The overhead of filtering out a large amount of unnecessary data that are...
Power Quality is a generic term focusing on several issues, going from reliability to the quality of service provided by the energy supplier. It addresses limiting aspects such as harmonic distortion, flicker, sags, swells and transients… It is important for the students to understand the differences between the large amounts of events that fit into poor power quality category. Moreover it is important...
A novel class of mobile Internet of Things applications falls under the category of mobile crowdsensing, whereby large amounts of sensed data are collected and shared by mobile sensing and computing devices for the purposes of observing phenomena of common interest (e.g., traffic monitoring, environmental monitoring). Challenges arise with respect to collecting and managing sensor data in an energy-...
We demonstrate an urban crowd sensing application for monitoring air quality by use of specially-designed wearable sensors and mobile phones. The application is built upon the OpenIoT platform1 with the goal to support context-aware and energy-efficient acquisition and filtering of sensor data in mobile environments while ensuring adequate sensing coverage. We demonstrate how sensors and mobile devices...
An approach is discussed to connect stand-alone devices to wireless services by adding Near Field Communication (NFC) capability to such devices. Research has shown that simple NFC interfaces can be built for the specific purpose of connecting to existing equipment that require regular monitoring or digital control. This fact can be exploited to enable wireless monitoring and control of both mobile...
This paper presents P-Sense (Pollution-Sense), a PS system for air pollution monitoring and control. The ultimate goal of this system is to allow government officials, international organizations, communities, and individuals access to the pollution data to address their particular problems and needs. P-Sense should provide large amounts of pollution data in time and space with different granularities...
For the management of urban land resources and real estate development, periodic updating of information is crucial, particularly in some cities where exist serious problems of land resources shortage. However, collecting information related real estate development through full ground surveys would be very costly and time-consuming. On the basis of related technologies of Mobile Geographic Information...

Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
This paper presents the synthesis of a SCADA (supervisory control and data acquisition) system, named Pollution Guard, designed to collect and process atmospheric pollution data measured in several strategic points of a region. Pollution Guard makes use of the GPRS (general packet radio service) data communication infrastructure from a mobile communication provider that covers a very large area, practically...
