Performance evaluation of a ZigBee-based medical sensor network

Abstract

Low power consumption and small footprint make 802.15.4/ZigBee based devices well suited for personal healthcare applications, representing a promising alternative to patient monitoring under important scenarios such as emergency, postop, continuous care, and chronic diseases. However, their use in a healthcare facility to monitor several mobile patients poses several difficulties, mainly because this protocol was primarily designed to operate in low data rate scenarios. This paper presents simulation results used to evaluate important quality of service (QoS) markers and, ultimately, estimate the maximum number of sensors that could integrate a wireless vital signs monitoring system. Results show that the system is able to carry the signals from 30 ECG sensors with delivery ratio higher than 99% in the considered scenario, provided that an adequate number of retransmissions are allowed.

Multi-Objective Optimization of Electrocardiogram Monitoring Network for Elderly Patient in Home

“…Health care consists of different types of IEEE 802.15.4 (Zigbee) health sensors [10] [11] that fixed and distributed in patient home rooms. These sensors work to sense and to determine patient health status (vital signals) like Electrocardiogram (ECG), blood pressure rate and heart rate.…”

Performance IEEE 802.14.5 and zigbee protocol on realtime monitoring augmented reality based wireless sensor network system

“…Lopez et.al. [6] describe ZigBee protocol performance in medical body sensor with simulation that have some weakness namely when it delay will increase data loss. Zhang [7] has used the Time Division Cluster Schedule (TDCS) on WSN as a periodic scheduling for avoiding the collision flow while meeting the end-to-end delay deadlines.…”
