Conserving Bandwidth In A Wireless Sensor Network For Telemedicine Application

Abstract

Telemedicine aided by wireless sensor networks (WSN) has recently become a healthcare trend. Many previous studies have adopted the ZigBee-based WSN to implement a platform and/or a telemedicine system. However, the low data rate and bandwidth have limited the maximum number of nodes in a WSN during continuous and simultaneous transmission. The issue of low data throughput has not been addressed in previous research. In this study, we propose an arrhythmia-aware system, and a new DSPbased WSN platform is developed for the high compression performance of physiological data in a ZigBee-based WSN. Proven by simulations and several real tests, the combination of the proposed platform and the sensor nodes can lead to more bandwidth conservation and extend the WSN scale for the next generation of telemedicine system.

Wireless Sensor Networks for Vital Signs Monitoring: Application in a Nursing Home

“…Many advantages of healthcare monitoring systems based on wireless sensor networks (WSNs) have been reported [6,7]. To improve the throughput of WSN, a DSP-based WSN platform was proposed [8]. To enhance the performance of communication, an integrated wireless health service system with 3G/3.5G and mobile devices was revealed in some researches [9][10][11][12][13].…”
