Analysis and Description of HOLTIN Service Provision for AECG monitoring in Complex Indoor Environments

Abstract

In this work, a novel ambulatory ECG monitoring device developed in-house called HOLTIN is analyzed when operating in complex indoor scenarios. The HOLTIN system is described, from the technological platform level to its functional model. In addition, by using in-house 3D ray launching simulation code, the wireless channel behavior, which enables ubiquitous operation, is performed. The effect of human body presence is taken into account by a novel simplified model embedded within the 3D Ray Launching code. Simulation as well as measurement results are presented, showing good agreement. These results may aid in the adequate deployment of this novel device to automate conventional medical processes, increasing the coverage radius and optimizing energy consumption.

Dense wireless sensor network design for the implementation of Smart Health environments

“…The developed tool has been tested under a wide range of situations and scenario and extensive analysis in terms of operational parameters to guarantee simulation convergence has been performed [10][11][12][13][14]. The proposed scenario is a set of buildings and streets have been implemented, in which transceivers are located in different positions, resembling realistic users, which can be depicted in In order to emulate the operation of different wireless systems, the transceivers operate in the frequency bands of 868 MHz, 2GHz and 2.4GHz, which corresponds to Wireless Sensor Networks (based mainly on 802.15 standards), 3G-4G mobile networks and a large portion of Wireless LAN networks.…”

“…Within this context, Smart Cities and Smart Regions are being envisaged in which interactive environments, where multiple systems interact in order to provide more optimal operation, are under active study. Such systems include energy systems and the inclusion of renewable energy sources, water distribution and management, waste disposal, transportation systems, electronic administration or e-Gov, among others [1][2][3][4][5][6]. A very particular case of interest arises when healthcare services are also taken into account, due to the relevance, direct impact in citizens life and the potentially high cost inherent in service provision, which is constantly increasing due to increase in population as well as in life expectancy.…”

Analysis of efficient dense wireless sensor network deployment in Smart City environments

“…As previously stated, in order to analyze wireless channel behaviour, a deterministic approach based on an in-house 3D ray launching code is employed. This simulation code, which considers electromagnetic interaction with the material elements of the scenario, as well as reflection, refraction and diffraction, has been tested in a wide range of complex environments [3][4][5][6][7][8]. The main simulation parameters that have been used for the scenario are shown in Table I.…”

Analysis of Radio Wave Propagation for ISM 2.4GHz Wireless Sensor Networks in Inhomogeneous Vegetation Environments

“…Different applications of this algorithm can be found in the literature, like the analysis of wireless propagation in closed environments [15][16][17][18], interference analysis [19] or electromagnetic dosimetry evaluation in wireless systems [20].…”
