Abstract
The most significant shortcoming of implanted devices is the battery life. With advanced technology, implanted devices can have the capability to communicate with other health-related devices, but this also means the energy consumption requirement is greater than ever. Less power consumption would extend the duration of the batteries of implanted medical devices. In this paper, an energy efficient and reliable communication service device scheme that does not require any modification to the existing wireless network structure or the implanted devices under consideration is proposed. The scheme is intended to save a target device's energy necessary for resending communication signals by introducing a neighbor group header node and cooperative (wearable) nodes. The simulation results show that the scheme would result in energy savings of 70 percent with one or two cooperative nodes as compared with the current best approach.
Highlights
The implant medical devices such as pacemaker, implantable cardiac defibrillator (ICD), neurostimulator system for deep brain stimulator, and insulin pump [1,2,3,4] are normally used to assist patient to maintain normal vital operation
Besides supporting vital operation, the rest of the function provided by the implanted device is to handle the transmission of physiological signals
We proposed an algorithm to select the header node
Summary
The implant medical devices such as pacemaker, implantable cardiac defibrillator (ICD), neurostimulator system for deep brain stimulator, and insulin pump [1,2,3,4] are normally used to assist patient to maintain normal vital operation. The proposed scheme is intended to introduce wearable devices that adopt a cooperative communication technique to help an IMD establish reliable communication and reduce retransmission. In order to ensure the quality and reliability of the signal transmission, our proposed scheme adopts cooperative approach. The proposed scheme is suitable for use in the medical and healthcare environment to provide more energy savings and a reliable environment for implanted medical device communication. This proposed scheme adopts the IEEE 802.15.6 and 802.11, which are already equipped with special secure communication capabilities; the proposed paper only focuses on communication reliability and energy consumption and does not include security issues
