An Integrated Gateway for Various PHDs in U-Healthcare Environments

Abstract

We propose an integrated gateway for various personal health devices (PHDs). This gateway receives measurements from various PHDs and conveys them to a remote monitoring server (MS). It provides two kinds of transmission modes: immediate transmission and integrated transmission. The former mode operates if a measurement exceeds a predetermined threshold or in the case of an emergency. In the latter mode, the gateway retains the measurements instead of forwarding them. When the reporting time comes, the gateway extracts all the stored measurements, integrates them into one message, and transmits the integrated message to the MS. Through this mechanism, the transmission overhead can be reduced. On the basis of the proposed gateway, we construct a u-healthcare system comprising an activity monitor, a medication dispenser, and a pulse oximeter. The evaluation results show that the size of separate messages from various PHDs is reduced through the integration process, and the process does not require much time; the integration time is negligible.

A multipurpose smart activity monitoring system for personalized health services

“…Activity monitors are one of the most popular types of PHDs (Personal Health Devices) [4,[15][16][17]. The activity monitor is normally attached to the wrist or waist to measure physical activity.…”

“…Some studies used sensors to track elderly persons [1,8,10,[17][18][19][20]26]. Pressure sensors [17,18] or capacitance sensors [19,20] are attached to a floor to locate a person on the floor.…”

“…Pressure sensors [17,18] or capacitance sensors [19,20] are attached to a floor to locate a person on the floor. Accurate localization and monitoring of a person can be obtained through these approaches.…”

Biomedical Data Management and Processing -A New Framework

“…Neste contexto, a área da Saúde apresenta inúmeras tarefas e aplicações que podem ser realizadas por meio de sistemas inteligentes, desde a utilização da tecnologia para auxiliar no gerenciamento e processamento de dados clínicos em simples planilhas informatizadas, até a criação de um modelo robusto de gerenciamento desses dados [1][2][3][4][5][6][7].…”

A Study on the Performance of a Multi-layered Management System

“…In recent years, PHDs (Personal Healthcare Devices) [1][2][3][4][5] have become popular mobile devices, and as a result remote PHD management/monitoring systems have been attracting attention in the u-healthcare field [6][7][8][9][10][11]. Some studies have proposed a hierarchical system for managing/monitoring a very large number of PHDs or objects [11][12].…”
