reusability in Body Sensor Networks (BSNs) has been presented
[50]. The developed model has been applied in the
context of gait analysis through wearable sensors. Wireless
Body Area Networks (WBAN) is seen as a great potential
in improving healthcare quality, and consequently used a in a
wide range of applications from ubiquitous health monitoring
and range of computer assisted rehabilitation to emergency
medical response systems [51]. The security and privacy
protection of the WBAN is a major unsolved concern, with
challenges coming from stringent resource constraints of
WBAN devices, and the high demand for both security/
privacy and practicality/usability. Though many researches
on BSNs are reported, there is still a significant gap in the
current research activities on BSNs to meet the requirements
of medical monitoring applications. A secure and resourceaware
BSN architecture enabling real-time healthcare monitoring,
especially for secure wireless electrocardiogram (ECG)
data streaming and monitoring has been presented [52].
A cross-layer framework has been developed based on unequal
resource allocation to support biomedical data monitoring
applications. In the developed framework important information
(e.g., major ECG data) has been identified, and extra
resources are allocated to protect its transmission. The reported
work in [53] focuses on the Wireless Sensor Network (WSN)
enhancements considering User Quality of Experience (QoE),
mainly oriented to reduce energy consumption and required
data transmission and consequently improving the autonomy
and range of the sensors. It is seen that the sensor network is
capable of handling the activities of person wearing sensors
for monitoring different activities.
