Energy Efficient Wireless Data Transmission for Personal Health Devices

Abstract

-The family of ISO/IEEE11073 standards is the basis of the e-health system and provides interoperability for personal health devices. In the early stage of e-health business, it was expected that people would use a health device individually. In this case, a measurement datum was episodically acquired and generally transmitted for one person at a time. Recently, a health device is expected to be used by multiple people, and large amounts of measurement data are gathered in a short time interval. In addition, mobile health devices have become more popular, so that energy efficient measurement data transmission is required, to prolong the use of a device. In IEEE11073 PHD standards, data transmission is classified into three different types: immediate individual transfer, small block transfer, and large block transfer. The large block transfer using PM-store concept provides efficient transmission. However, an existing PM-store has problem when a device is used by multiple people. To address the defined problem, a modified PM-segment that is in compliance with 11073 standards is proposed in this paper. In particular, the proposed PM-segment is designed to minimize the additional complexity of an agent instead of a manager and it is interoperable with the existing manager. The proposed PM-segment shows better performance than the existing PM-segment, in terms of memory requirements and expected queue time. Also, performance comparison among the three transfers is performed in regard to the delay time and communication power consumption points of view.

A Novel Transmission Scheme for Compressed Health Data Using ISO/IEEE11073-20601

“…In fact, a reliable communication environment characterized by seamless connectivity, minimum transmission capacity, and maximum latency for ECG should be guaranteed. However, while the 20601 OEP can use PM-store(s) to transmit a large amout of ECG data in an energy-efficient way, it cannot properly support real-time monitoring system in an unreliable wireless environment [13]. In other words, considering limited wireless capacity and unstable channel conditions, appropriate signal processing and transmission techniques such as compression are required.…”

Critical Data Delivery Using TOPSIS in Wireless Body Area Networks

“…The critical data from the patient's body has to be transmitted in a reliable manner without affecting the actual observed body parameters to the medical evaluator [3] [4]. So, in this case, finding the critical data is more important for selecting the patient with abnormalities to detect and diagnose the patient to save their life through e-health [5].…”
