Abstract
This paper presents a system based on WSN technology capable of monitoring heart rate and the rate of motion of seniors within their homes. The system is capable of remotely alerting specialists, caretakers or family members via a smartphone of rapid physiological changes due to falls, tachycardia or bradycardia. This work was carried out using our workgroup's WiSe platform, which we previously developed for use in WSNs. The proposed WSN architecture is flexible, allowing for greater scalability to better allow event-based monitoring. The architecture also provides security mechanisms to assure that the monitored and/or stored data can only be accessed by authorized individuals or devices. The aforementioned characteristics provide the network versatility and solidity required for use in health applications.
Highlights
Each time the subjects’ heart rates exceeded the 100 beats per minute (BPM) limit, the events were transmitted to the network and received by the SINK
The byte defines the frame type which corresponds to the IEEE 802.15.4 standard (0 × 81-R × 16 indicator), followed by 2 bytes for the source address, 1 byte for the Received Signal Strength Indication (RSSI), and 1 byte for the method sent (0 × 00 for unicast, 0 × 02 for broadcast), which, in this case, is broadcast mode
This paper has presented a Home Care Monitoring System (WiSPH), which represents a potentially valuable tool to assist caretakers, family members or health care practitioners to monitor the heart rate and potentially dangerous falls of elderly patients who can still live independent, but assisted lifestyles
Summary
Projections show that between 2000 and 2050 the number of people above the age of 60 will increase from 11% to 22%. Aging presents a series of challenges for the entire world population, primarily because seniors slowly lose their ability to be self-sufficient due to chronic diseases, physical and/or mental disabilities, or the general frailty that characterizes the aging process [2]. Any of these conditions represent factors that limit the elderly or endanger their lives, even within the confines of their homes
