Validation of Wired and Wireless Interconnected Body Sensor Networks

Abstract

Current medical facilities usually lead to a very high cost especially for developing countries, rural areas and mass casualty incidents. Therefore, advanced electronic health systems are gaining momentum. In this paper, we first compared our novel off the shelf experimental wired Body Sensor Networks (BSN), that is, Digital First Aid (DigiAID) with the existing commercial product called as Hexoskin. We showed the viability of DigiAID through extensive real measurements during daily activities by both male and females. It was found that the major hurdle was wires to be worn by the subjects. Accordingly, we proposed and characterized the wireless DigiAID platform for wireless BSN (WBSN). Understanding the effect of body movements on wireless data transmission in WBSN is also of major importance. Therefore, this paper comprehensively evaluates and analyzes the impact of body movements, (a) to ensure transmission of data at different radio power levels and (b) its impact on the topology of the WBSN. Based on this we have proposed a dynamic power control algorithm that adapts the transmitting power according to the packet reception in an energy efficient manner. The results show that we have achieved substantial power savings at various nodes attached to the human body.

A novel countermeasure technique to protect WSN against denial-of-sleep attacks using firefly and Hopfield neural network (HNN) algorithms

“…The PDR obtained for n experiments is shown by Eq. (14)[30][31][32][33][34]. Prolong the lifetime of the network is the main goal of WSNs.…”

Clinical evaluation of stretchable and wearable inkjet-printed strain gauge sensor for respiratory rate monitoring at different measurements locations

“…The results obtained from the developed sensor are compared with the results from the reference nasal e-Health sensor (e-Health AirFlow sensor, Cooking Hacks) which was validated by several studies in the literature [31]- [34]. The e-Health sensor detects the variation in temperature of the nasal airflow.…”

Wearable Sensors for Monitoring and Preventing Noncommunicable Diseases: A Systematic Review

“…This is not strange considering that Hexoskin collects data using a one-channel ECG sensor. Talpur et al (2019) [65] noted that the HR values collected using the wired DigiAID were acceptable, but not satisfactory. Studying the sleep activity data, the RR data were fluctuating for both systems, but within the reference RR range for all participants with the wired DigiAID.…”

“…The authors found the sensors reliable and stable for EEG signal acquisition. Talpur et al (2019) [65] presented a wearable, but wired off-the-shelf sensor network, DigiAID, that included a pulse oximeter for measuring HR, an airflow sensor for measuring RR and a position sensor. The viability of using the wired DigiAID for measuring HR and RR was determined by comparing the sensor data collected with data collected using the Hexoskin garment.…”

“…While the wired DigiAID was found to perform well in comparison with Hexoskin, participants found that being connected to a wired sensor system prohibited smooth performing of the activities. Therefore, the authors [65] also presented a wireless version of DigiAID that takes input from nine sensors (IRIS motes). An equal number of participants, although it was unclear whether they were the same ten participants as in the first experiment or not, conducted the activities while data were collected.…”
